From baa4636ff73ace522cd0fa240f595a594ee88d65 Mon Sep 17 00:00:00 2001 From: Rohit Goswami Date: Sun, 10 May 2026 00:21:43 +0200 Subject: [PATCH 01/59] fix(meson): banner reports LAMMPS as enabled when always compiled LAMMPS is unconditionally compiled into the client (see client/meson.build subdir('potentials/LAMMPS') with comment 'always compiled, loaded at runtime via dlopen'). Yet the features banner check at line 168 looks for -DLAMMPS_POT in the compile-args string -- a flag the meson build never sets, so LAMMPS was always reported as 'disabled'. Extends the features_list tuple to (flag, name, mode): 'compile' -- existing behaviour, check -Dflag in _args_str 'runtime' -- always compiled in; LammpsLoader::instance() does the dlopen lookup at run time LAMMPS now reads 'enabled (dlopen at runtime)' which matches reality. Other entries unchanged. Note: the runtime-loaded report does NOT verify liblammps.so is actually present on LD_LIBRARY_PATH; that diagnostic still comes from LammpsLoader::require_loaded() throwing when a LAMMPS potential is requested without the library. --- client/meson.build | 51 +++++++++++++++++++++++++++++----------------- 1 file changed, 32 insertions(+), 19 deletions(-) diff --git a/client/meson.build b/client/meson.build index 401ec58e4..64f33169d 100644 --- a/client/meson.build +++ b/client/meson.build @@ -137,25 +137,35 @@ architecture = host_machine.cpu_family() message(host_system) message(architecture) -# Generate features string for version.h.in +# Generate features string for version.h.in. +# +# Each entry is (compile_flag, display_name, mode) where mode is one of: +# 'compile' -- check '-Dflag' presence in _args (Build-time CPP define) +# 'runtime' -- always compiled into the client; loaded later via dlopen. +# Reporting 'enabled' here means the compiled-in shim exists, +# not that the dynamic library was found at run time. features_list = [ - ['WITH_GPRD', 'GPRD'], - ['WITH_GP_SURROGATE', 'GP Surrogate'], - ['WITH_CATLEARN', 'CatLearn'], - ['WITH_VASP', 'VASP'], - ['WITH_WATER', 'Water'], - ['WITH_AMS', 'AMS'], - ['WITH_XTB', 'XTB'], - ['LAMMPS_POT', 'LAMMPS'], - ['WITH_ASE_POT', 'ASE Potentials'], - ['EONMPI', 'MPI'], - ['WITH_FORTRAN', 'Fortran'], - ['CUH2_POT', 'CuH2'], - ['WITH_ASE_ORCA', 'ASE-ORCA'], - ['WITH_ASE_NWCHEM', 'ASE-NWChem'], - ['WITH_METATOMIC', 'Metatomic'], - ['WITH_SERVE_MODE', 'Serve Mode'], - ['EMBED_PYTHON', 'Embedded Python'], + ['WITH_GPRD', 'GPRD', 'compile'], + ['WITH_GP_SURROGATE', 'GP Surrogate', 'compile'], + ['WITH_CATLEARN', 'CatLearn', 'compile'], + ['WITH_VASP', 'VASP', 'compile'], + ['WITH_WATER', 'Water', 'compile'], + ['WITH_AMS', 'AMS', 'compile'], + ['WITH_XTB', 'XTB', 'compile'], + # LAMMPS is unconditionally compiled (see subdir('potentials/LAMMPS') + # below).

Both have *Resource classes that follow the LammpsLoader pattern (dynlib::openFirst then dlsym, with require_loaded() throwing only when the user actually requests the feature). Unlike LAMMPS, they're conditionally compiled (with_artn / with_ira meson options control inclusion of the resource shim AND set -DWITH_ARTN / -DWITH_IRA). Adds 'compile_runtime' mode to features_list: -DWITH_ARTN/IRA in args -> 'enabled (dlopen at runtime)' not in args -> 'disabled' Metatomic verified as compile-LINKED (not dlopen): the client/potentials/Metatomic/meson.build links metatomic_pot via library() with link_with, no dynlib::openFirst pattern. The existing 'compile' mode for WITH_METATOMIC is correct. Docs (user_guide/lammps_pot.md): clarifies in.lammps file placement. - akmc.py / parallel_replica / basin_hopping (multi-job drivers): put in.lammps in potfiles/ next to config.ini. The Python driver copies them per-job scratch dir before each eonclient launch. - Direct single-job eonclient invocations (job = minimization | nudged_elastic_band | single_point | process_search): in.lammps + parameter files MUST be in the SAME dir as config.ini. LAMMPSPot calls lammps_file("in.lammps") with a relative path; missing-file is silent and the next force evaluation segfaults inside LAMMPSPot::force. Symptoms documented: 'eonclient segfaults inside LAMMPSPot::force immediately after Beginning minimization / Beginning NEB' = check in.lammps location. Discovered while debugging Cu V/SIA recombination NEB; gdb backtrace showed eonclient SEGV at LAMMPSPot::force +0x155 from relaxMatter -> Matter::computePotential.

The content is opaque to eOn -- the packer walks a directory and the client untars it. LAMMPSPot now has two operating modes: bundle mode -- [Potential] lammps_bundle = path/to/run.eonlpb. LAMMPSBundle::extract() unpacks into a per-instance scratch dir under temp_directory_path() (PID + 64-bit random suffix to avoid collisions). The makeNewLAMMPS() path issues "shell cd " to liblammps so every relative path inside in.lammps resolves there. Scratch is removed in the destructor. legacy mode -- bundle path empty. Behaviour matches pre-2.15: in.lammps and every file it references must live in eonclient's CWD. Bundle format is plain little-endian: [0..7] magic "EONLPB1\0" [8..15] uint64 manifest length [16..] JSON {"files": [{"name": ..., "size": ...}, ...]} [...] concatenated file bodies Pack and inspect with the new eon.lammps_bundle module: python -m eon.lammps_bundle pack potfiles/ run.eonlpb python -m eon.lammps_bundle list run.eonlpb (2) Fail loudly on missing in.lammps (issue eon-7qqp) LAMMPSPot's constructor now refuses to build the potential if legacy mode is active and in.lammps is absent from CWD; the runtime_error names the CWD and points at the bundle option. Previously lammps_file() silently logged its own error and the next force() segfaulted on a null pair_style. LammpsLoader gained two optional symbols: lammps_has_error lammps_get_last_error_message Present in LAMMPS >= 3Mar2020, null on older builds. After lammps_file() we surface the LAMMPS-side message verbatim instead of pressing on with a half-initialised handle.

Modern conda-forge MPICH 4.x and OpenMPI 5.x do not ship mpicxx.h, so -Dwith_mpi=true has been a build-time error on those platforms.

MPI::INT / MPI::DOUBLE -> MPI_INT / MPI_DOUBLE. The local icwd buffer goes from long[1024] to int[1024] so the over-the-wire layout matches the existing MPI server: the pre-port code declared long[1024] but tagged the message MPI::INT, which on little-endian sent the low 4 bytes of each long. Any deployed MPI server still parses 1024 MPI_INTs correctly with the new buffer. client/ClientEON.cpp MPI::Init / Is_initialized -> MPI_Init / MPI_Initialized.

This solves the same problem the LAMMPS / ARTn / IRA / XTB dlopen loaders solve for their respective libraries -- one binary, many runtime backends. The meson detection order in -Dwith_mpi=true builds: 1. dependency('MPItrampoline', method: 'cmake') Picks up the upstream CMake config that installs alongside libmpitrampoline.so. Preferred path. 2. dependency('mpi-c') MPItrampoline also installs a pkg-config shim that shadows the system mpi-c.pc; this catches conda-style installs where pkg-config wins over CMake. 3. dependency('mpi', required: true) Last-resort direct link to the system MPI. Builds against that single flavour the way pre-2.15 always did. subprojects/mpitrampoline.wrap pins upstream v5.5.1 so users who want meson to fetch and CMake-build the trampoline locally can just `meson subprojects download mpitrampoline` instead of installing it separately.

The root cause is that NaN-tainted force vectors (from atom overlap inside an EAM/ML repulsive core after a too-large push from the saddle) propagate silently through every comparison in the line-search loop -- 'NaN < threshold' is false, so the loop condition never terminates and the minimizer keeps retrying with shrinking step sizes that all evaluate to NaN. Add a single allFinite() guard at the entry to LBFGS::step() and ConjugateGradients::step() that returns -1 the moment a non-finite element appears in the gradient. The respective run() loops already treat status<0 as a hard failure (LBFGS) or now do (CG); both also re-check after the loop in case isConverged() silently swallowed a NaN comparison. Effect: a NaN-locked minimization terminates with a clear "non-finite force" warning instead of a SLURM-killed hang. The job returns a -1 status the akmc.py wrapper can route to a clean termination_reason instead of leaving an entire chain-state combo indefinitely waiting on output. --- client/ConjugateGradients.cpp | 20 ++++++++++++++++++- client/LBFGS.cpp | 18 +++++++++++++++++ .../338-min-nan-bailout.fixed.md | 1 + 3 files changed, 38 insertions(+), 1 deletion(-) create mode 100644 docs/newsfragments/338-min-nan-bailout.fixed.md diff --git a/client/ConjugateGradients.cpp b/client/ConjugateGradients.cpp index 0febac63a..049fc7365 100644 --- a/client/ConjugateGradients.cpp +++ b/client/ConjugateGradients.cpp @@ -43,6 +43,18 @@ Eigen::VectorXd ConjugateGradients::getStep() { } int ConjugateGradients::step(double a_maxMove) { + // Bail out instead of looping forever when the potential returns + // NaN forces (atom overlap inside an EAM/ML repulsive core, etc.). + // NaN propagates through dot products and < comparisons silently; + // without this guard line_search keeps shrinking the step and never + // exits because isConverged() never sees a finite-norm check. + if (!m_objf->getGradient().allFinite()) { + QUILL_LOG_WARNING(m_log, + "[CG] non-finite force entering step (NaN or Inf); " + "aborting minimization"); + return -1; + } + bool converged; if (m_optConfig.opts.cg.line_search) { converged = line_search(a_maxMove); @@ -191,8 +203,14 @@ int ConjugateGradients::single_step(double a_maxMove) { int ConjugateGradients::run(size_t a_maxIterations, double a_maxMove) { size_t iterations = 0; while (!m_objf->isConverged() && iterations <= a_maxIterations) { - step(a_maxMove); + int status = step(a_maxMove); + if (status < 0) { + return -1; + } iterations++; } + if (!m_objf->getGradient().allFinite()) { + return -1; + } return m_objf->isConverged() ? 1 : 0; } diff --git a/client/LBFGS.cpp b/client/LBFGS.cpp index 7a2db8ee1..7c1d86e8d 100644 --- a/client/LBFGS.cpp +++ b/client/LBFGS.cpp @@ -146,6 +146,19 @@ int LBFGS::step(double a_maxMove) { Eigen::VectorXd r = m_objf->getPositions(); Eigen::VectorXd f = -m_objf->getGradient(); + // Bail out instead of looping when the underlying potential returns + // NaN forces (e.g., the post-saddle push placed two atoms inside + // the EAM repulsive core; LAMMPS / xtb / ASE all return NaN there). + // Without this guard isConverged() / line-search comparisons all + // evaluate to false on NaN, and run() spins forever. + if (!f.allFinite()) { + QUILL_LOG_WARNING(m_log, + "[LBFGS] non-finite force at iteration {} (NaN or " + "Inf); aborting minimization", + m_iteration); + return -1; + } + if (m_iteration > 0) { status = update(r, m_rPrev, f, m_fPrev); } @@ -171,5 +184,10 @@ int LBFGS::run(size_t a_maxSteps, double a_maxMove) { if (status < 0) return -1; } + // isConverged() returns false on a NaN convergence test even when + // step() succeeded, so guard the final return too. + if (!m_objf->getGradient().allFinite()) { + return -1; + } return m_objf->isConverged() ? 1 : 0; } diff --git a/docs/newsfragments/338-min-nan-bailout.fixed.md b/docs/newsfragments/338-min-nan-bailout.fixed.md new file mode 100644 index 000000000..ae5f50bb7 --- /dev/null +++ b/docs/newsfragments/338-min-nan-bailout.fixed.md @@ -0,0 +1 @@ +LBFGS and Conjugate-Gradient minimizers no longer hang when the underlying potential returns NaN forces (issue eon-7416).

Replace the historical chain of `eonclib_sources +=` accretions with a single sourceset: eonclib_ss = import('sourceset').source_set() eonclib_ss.add(files()) # ARTn / IRA included eonclib_ss.add(when: 'WITH_GPRD', if_true: files(...)) eonclib_ss.add(when: 'WITH_GP_SURROGATE', if_true: files(...)) eonclib_ss.add(when: 'WITH_SERVE_MODE', if_true: files(...)) eonclib_cfg = configuration_data() eonclib_cfg.set('WITH_GPRD', get_option('with_gprd')) eonclib_cfg.set('WITH_GP_SURROGATE', get_option('with_gp_surrogate')) eonclib_cfg.set('WITH_SERVE_MODE', get_option('with_serve')) eonclib_resolved = eonclib_ss.apply(eonclib_cfg) library('eonclib', sources: eonclib_resolved.sources(), ...) Source membership now lives in one place; feature blocks keep their side-effecting parts (subproject() calls, find_library, -DWITH_X defines, _deps additions) but no longer reach into the source list. Build output is byte-identical to the pre-cleanup chain -- sourceset.apply() produces the same deduplicated list. The sourceset module also positions us to add per-feature dependency tracking later (`when: 'WITH_X', if_true: dep_x`), which is the right place to land further consolidation when AMS / metatomic get the same treatment. --- client/meson.build | 207 +++++++++++------- .../338-meson-sourceset.changed.md | 1 + 2 files changed, 123 insertions(+), 85 deletions(-) create mode 100644 docs/newsfragments/338-meson-sourceset.changed.md diff --git a/client/meson.build b/client/meson.build index 3c9516fba..7211905b3 100644 --- a/client/meson.build +++ b/client/meson.build @@ -383,71 +383,114 @@ if not is_windows potentials += [socket_nwchem] endif -eonclib_sources = [ - 'Parameters.cpp', - 'ParametersINI.cpp', - 'ParametersJSON.cpp', - 'ConFileIO.cpp', - 'GeometryAnalysis.cpp', - 'Optimizer.cpp', - 'IDPPObjectiveFunction.cpp', - 'PrefactorJob.cpp', - 'LBFGS.cpp', - 'ReplicaExchangeJob.cpp', - 'BondBoost.cpp', - 'Job.cpp', - 'GlobalOptimization.cpp', - 'LowestEigenmode.cpp', - 'MinModeSaddleSearch.cpp', - 'StructureComparisonJob.cpp', - 'SteepestDescent.cpp', - 'ImprovedDimer.cpp', - 'PointJob.cpp', - 'Prefactor.cpp', - 'ConjugateGradients.cpp', - 'Matter.cpp', - 'FiniteDifferenceJob.cpp', - 'Lanczos.cpp', - 'HessianJob.cpp', - 'ReplicaDynamicsJob.cpp', - 'TADJob.cpp', - 'ProcessSearchJob.cpp', - 'Bundling.cpp', - 'NEBInitialPaths.cpp', - 'NEBForceProjection.cpp', - 'NEBObjectiveFunction.cpp', - 'NEBProjection.cpp', - 'NEBOcinebController.cpp', - 'NEBSplineExtrema.cpp', - 'NEBSpringForce.cpp', - 'NEBTangent.cpp', - 'NudgedElasticBand.cpp', - 'MonteCarloJob.cpp', - 'DynamicsJob.cpp', - 'MonteCarlo.cpp', - 'Hessian.cpp', - 'NudgedElasticBandJob.cpp', - 'DynamicsSaddleSearch.cpp', - 'HelperFunctions.cpp', - 'RandomNumbers.cpp', - 'StringHelpers.cc', - 'MatrixHelpers.hpp', # Template - 'Dimer.cpp', - 'Dynamics.cpp', - 'GlobalOptimizationJob.cpp', - 'BiasedGradientSquaredDescent.cpp', - 'SafeHyperJob.cpp', - 'MinimizationJob.cpp', - 'Quickmin.cpp', - 'ParallelReplicaJob.cpp', - 'Potential.cpp', - 'SurrogatePotential.cpp', # Part of the interface - 'BasinHoppingJob.cpp', - 'FIRE.cpp', - 'EpiCenters.cpp', - 'SaddleSearchJob.cpp', - 'BasinHoppingSaddleSearch.cpp', -] +# eonclib source set (issue #177).

Pre-fix only potentials/LAMMPS/meson.build had a local dl_dep, and the new XtbLoader / ARTn / IRA paths inherited `_deps` without it -- libxtbeon.so failed to link with `undefined reference to dlopen / dlsym / dlclose` on every Linux CI runner. Drop the redundant local dl_dep from potentials/LAMMPS/meson.build. 2. Catch2 --allow-running-no-tests Catch2 v3 returns exit 4 from a process that ran no tests / no assertions even when every TEST_CASE issued SKIP() cleanly. Pass --allow-running-no-tests to every Catch2 unit test in the test() loop so test_xtb / test_artn / test_ira / test_cineb_xtb skip silently with exit 0 on systems where libxtb / libartn / libira isn't on LD_LIBRARY_PATH (e.g. macOS CI without libxtb). 3. Optional torch component lookup (closes #304) Make the libtorch find_library loop required: false and skip missing libraries. The CMake build's find_package(Torch) handles missing components gracefully and so do we now; this unblocks Windows where torch_global_deps ships only a .dll (no .lib import library) and conda-forge libtorch *cpu* installs that strip torch_cuda. Combined with the with_xtb -> always-compile + dlopen change earlier in this PR (issue #304 item 1), the dependency('xtb') fallback removal (item 2), and the VLA -> std::vector swap inside the XTBPot rewrite (item 3), all four meson cross-platform packaging items in #304 are upstream: #304 (1) with_xtb forcing Fortran -- with_xtb is gone #304 (2) xtb fallback triggering source builds -- no dependency('xtb') anymore #304 (3) VLA in XTBPot.cpp -- replaced by std::vector R_bohr(3 * N) in the XtbLoader rewrite #304 (4) Torch find_library unconditional -- this commit --- client/meson.build | 38 ++++++++++++++++--- client/potentials/LAMMPS/meson.build | 7 ++-- docs/newsfragments/338-catch2-skip.fixed.md | 1 + docs/newsfragments/338-link-libdl.fixed.md | 1 + .../338-torch-find-required-false.fixed.md | 1 + 5 files changed, 40 insertions(+), 8 deletions(-) create mode 100644 docs/newsfragments/338-catch2-skip.fixed.md create mode 100644 docs/newsfragments/338-link-libdl.fixed.md create mode 100644 docs/newsfragments/338-torch-find-required-false.fixed.md diff --git a/client/meson.build b/client/meson.build index 7211905b3..b7475dd80 100644 --- a/client/meson.build +++ b/client/meson.build @@ -9,6 +9,20 @@ add_languages('c', required: true) cc = meson.get_compiler('c') cppc = meson.get_compiler('cpp') +# DynLib.h (used by LammpsLoader / XtbLoader / ARTnResource / +# IRAResource and any future runtime-loaded shim) calls dlopen + +# dlsym + dlclose on POSIX.

Pre-2.15 we shipped 0 to suppress build noise ahead of the CECAM school (#117); the suppression has outlived its use. warning_level=2 (-Wall -Wextra) and =3 (which also passes -fimplicit-none and breaks the vendored Fortran TUs that rely on implicit typing) are tracked as follow-ups in #117. 2. -fvisibility=hidden + -fvisibility-inlines-hidden applied via add_project_arguments in client/meson.build. Cuts the dynamic symbol table on libeonclib.so by ~10x, speeds up rtld lookups in conda envs, stops internal namespace symbols from leaking. cppc.get_supported_arguments() filters out flags MSVC doesn't accept, so the same line is a no-op on Windows (PE/COFF treats every function as private until __declspec(dllexport)). Public entry points the embedding host needs can opt back in via __attribute__((visibility("default"))) per-symbol; the eonclient binary itself is unaffected. 3. dependency('pybind11') resolved once via a need_pybind11 flag covering the four blocks that previously each ran the lookup (with_catlearn / with_ase / with_ase_orca / with_ase_nwchem). Configure-time logs cleaner; same _deps end state. 4.

Revert the global `-fvisibility=hidden` from earlier in this PR. It hid Matter::compare in libeonclib.so so linking eonclient against the lib failed with `undefined reference to eonc::Matter::compare(eonc::Matter const&, bool)`. To use -fvisibility=hidden cleanly we'd have to annotate every cross-DSO entry point in libeonclib (Matter::*, Potential::*, Job::*, ...) with __attribute__((visibility("default"))) -- a separate multi-day refactor. Keep -fvisibility-inlines-hidden; it only affects inline / template-instantiation symbols and doesn't change cross-DSO linkage. cppc.get_supported_arguments() filters out the flag on MSVC where it isn't accepted. 2. Migrate the 10 [[deprecated]] constructor call sites that warning_level=1 surfaced. Every Optimizer subclass and every Dynamics instantiation was still calling the legacy "Pass {Optimizer,Dynamics}Config directly" ctors. Replace with the {Optimizer,Dynamics}Config::fromParams(params) form already used by FIRE. client/LBFGS.h client/Quickmin.h client/SteepestDescent.h client/ConjugateGradients.h client/DynamicsSaddleSearch.cpp client/ParallelReplicaJob.cpp (2 sites) client/ReplicaDynamicsJob.cpp client/SafeHyperJob.cpp client/TADJob.cpp End state: a clean -Wall build with zero deprecated-declarations warnings.

Two changes: 1. NEBInitialPaths.cpp::sidppPath gcc 13's -Wstringop-overread fired on the QUILL_LOG_INFO call. The `use_zbl ? "-ZBL" : ""` ternary fed a const char* into quill's safe_strnlen specialisation that calls memchr with n=SIZE_MAX; the optimizer can't prove the early-exit at the null terminator and the source-size analysis trips on the 5- byte literal. Bind the literal to a sized std::string before logging so quill's encoding takes the string overload that already knows the length. 2. Optimizer / LBFGS / Quickmin / SteepestDescent / CG / FIRE Pass std::shared_ptr by value into every ctor and std::move into the base m_objf storage. Avoids the per-construction refcount bump that performance-unnecessary-value-param flagged. Derived ctors that previously read a_objf->degreesOfFreedom() now read through the base m_objf member that just got the moved-in value -- semantically identical, no extra copy.

POSIX leaves sa_flags + the sa_mask scratch area undefined when the struct is built by hand; we already overwrote sa_sigaction / sa_flags / sa_mask but the others (sa_restorer on Linux, sa_handler union member when sa_sigaction isn't picked) drifted from whatever junk the stack carried.

Switch to `std::stoi` inside a try / catch that swallows parse errors as "skip this filename" -- the surrounding `isdigit(numstr[0])` check guarantees the first char parses, and stoi only throws on overflow / wholly-bogus input which we'd want to skip anyway.

Categorised by remediation: Real error path -- must surface to the caller: Parameters.cpp:Parameters::load(FILE*) fseek/ftell/fread results checked; abort with EONC_LOG_ERROR and `return 1` on any failure. HelperFunctions.cpp:loadMode(FILE*, int) fscanf return checked against expected 3-double match; EONC_LOG_CRITICAL + std::exit(1) on a short read so the mode-direction file isn't silently parsed as zeros. HelperFunctions.cpp:saveMode(FILE*, ...) fprintf return checked; EONC_LOG_CRITICAL + std::exit(1) on a short write rather than dropping data on the floor. Signature updated to `const std::shared_ptr&` + `const AtomMatrix&` to match (and the matching declaration in HelperFunctions.h). BasinHoppingJob.cpp:188-192 `char fname[128]; snprintf(...)` -> `std::string fname = std::format(...)`. Removes the truncation hazard entirely. No-recovery path -- explicit (void) cast to silence: ConFileIO.cpp:writeMatterCon writes are best-effort -- if the fprintf chain fails partway through there's no way to recover once the header has been emitted, so cast each fprintf and the closing fclose to (void). HelperFunctions.cpp:loadMode RAII closer fclose ignored at scope-exit; the buffer was read-only so flushing-write failure is impossible.

Bundling.cpp:catch -- attach a std::cerr line to the formerly empty std::stoi catch (bugprone-empty-catch). Follow-up not in this commit: the Optimizer / SaddleSearchMethod status-int return values are still magic-number style (-1 / 0 / 1). A typed enum (`enum class StepResult { Failed, Step, Converged }`) would be the right move and crosses every call site -- separate focused branch. --- client/AtomicGPDimer.cpp | 5 +-- client/AtomicGPDimer.h | 3 +- client/BiasedGradientSquaredDescent.cpp | 13 ++++---- client/Bundling.cpp | 14 ++++++-- client/ConFileIO.cpp | 5 +-- client/ConFileIO.h | 2 +- client/Dimer.cpp | 6 ++-- client/Dimer.h | 7 ++-- client/GPSurrogateJob.cpp | 6 ++-- client/GeometryAnalysis.cpp | 33 ++++++++++--------- client/GeometryAnalysis.h | 24 +++++++------- client/HelperFunctions.cpp | 14 ++++---- client/HelperFunctions.h | 13 ++++---- client/IDPPObjectiveFunction.cpp | 14 +++++--- client/ImprovedDimer.cpp | 6 ++-- client/ImprovedDimer.h | 7 ++-- client/Lanczos.cpp | 10 +++--- client/Lanczos.h | 5 +-- client/Matter.cpp | 13 ++++++-- client/MinModeSaddleSearch.cpp | 9 ++--- client/MinModeSaddleSearch.h | 2 +- client/NEBObjectiveFunction.cpp | 18 ++++++---- client/NEBOcinebController.cpp | 5 +-- client/NEBSplineExtrema.cpp | 2 +- client/NEBSplineExtrema.h | 2 +- client/NudgedElasticBand.cpp | 5 +-- client/Optimizer.cpp | 6 ++-- client/Optimizer.h | 5 +-- client/RandomNumbers.cpp | 10 ++++-- client/ReplicaExchangeJob.cpp | 17 ++++++---- client/SurrogatePotential.cpp | 4 +-- client/SurrogatePotential.h | 3 +- .../potentials/Metatomic/pch/metatomic_pch.h | 2 +- 33 files changed, 171 insertions(+), 119 deletions(-) diff --git a/client/AtomicGPDimer.cpp b/client/AtomicGPDimer.cpp index dee14a592..cd4f79304 100644 --- a/client/AtomicGPDimer.cpp +++ b/client/AtomicGPDimer.cpp @@ -17,6 +17,7 @@ #include "fpe_handler.h" #include #include +#include #include "subprojects/gpr_optim/gpr/AtomicDimer.h" #include "subprojects/gpr_optim/gpr/auxiliary/ProblemSetUp.h" @@ -28,7 +29,7 @@ const char AtomicGPDimer::OPT_LBFGS[] = "lbfgs"; AtomicGPDimer::AtomicGPDimer(std::shared_ptr matter, const Parameters ¶ms, std::shared_ptr pot) - : LowestEigenmode(pot, params) { + : LowestEigenmode(std::move(pot), params) { matterCenter = std::make_shared(pot, params); *matterCenter = *matter; p = eonc::helpers::eon_parameters_to_gpr(params); @@ -38,7 +39,7 @@ AtomicGPDimer::AtomicGPDimer(std::shared_ptr matter, } void AtomicGPDimer::compute(std::shared_ptr matter, - AtomMatrix initialDirectionAtomMatrix) { + const AtomMatrix &initialDirectionAtomMatrix) { atoms_config = eonc::helpers::eon_matter_to_atmconf(matter.get()); // R_init.resize(1, matterCenter->getPositionsFree().size()); // R_init.assignFromEigenMatrix(matterCenter->getPositionsFreeV()); diff --git a/client/AtomicGPDimer.h b/client/AtomicGPDimer.h index b52ba1912..e7b97079b 100644 --- a/client/AtomicGPDimer.h +++ b/client/AtomicGPDimer.h @@ -34,7 +34,8 @@ class AtomicGPDimer : public LowestEigenmode { std::shared_ptr pot); ~AtomicGPDimer() = default; - void compute(std::shared_ptr matter, AtomMatrix initialDirection); + void compute(std::shared_ptr matter, + const AtomMatrix &initialDirection); double getEigenvalue(); AtomMatrix getEigenvector(); diff --git a/client/BiasedGradientSquaredDescent.cpp b/client/BiasedGradientSquaredDescent.cpp index 75c6c15ca..de2811b34 100644 --- a/client/BiasedGradientSquaredDescent.cpp +++ b/client/BiasedGradientSquaredDescent.cpp @@ -153,13 +153,12 @@ int BiasedGradientSquaredDescent::run() { eigenvector = eonc::eigenmodeGetEigenvector(*minModeMethod); eigenvalue = eonc::eigenmodeGetEigenvalue(*minModeMethod); QUILL_LOG_DEBUG(log, "lowest eigenvalue {:.8f}", eigenvalue); - if (objf2->isConvergedV()) { - return 0; - } else if (objf2->isConvergedIP()) { - return 1; - } else { - return 1; - }; + // Two convergence flavours: V (true convergence on a saddle) and + // IP (inflection-point fallback). isConvergedIP() and the trailing + // else both signal "not-V converged"; the chained if previously + // landed both on `return 1` -- bugprone-branch-clone fired.

Add client/StatusTypes.h with two strongly-typed enums: enum class StepResult : int { Failed = -1, NotConverged = 0, Converged = 1 }; enum class SaddleStatus : int { Good = 0, Init = 1, ... }; // 22+1 states This commit migrates `Optimizer::step()` / `Optimizer::run()` (and every subclass: LBFGS, ConjugateGradients, FIRE, Quickmin, SteepestDescent) from `int` returns to `StepResult`. Driver call sites that captured the return value (MinModeSaddleSearch::run's optStatus) switch to comparing against `StepResult::Failed` rather than the bare `< 0` check; sites that discard the return (NEBInitialPaths, NudgedElasticBand, BiasedGradientSquaredDescent, HelperFunctions::relaxMatter) compile unchanged. Underlying integer values are preserved (`Failed = -1`, `NotConverged = 0`, `Converged = 1`) so any out-of-tree code that read the int continues to do so via to_int(StepResult). Followup commit applies SaddleStatus to MinModeSaddleSearch / ARTnSaddleSearch / BasinHoppingSaddleSearch / BiasedGradientSquaredDescent / DynamicsSaddleSearch and the SaddleSearchMethod base. --- client/ConjugateGradients.cpp | 24 ++--- client/ConjugateGradients.h | 4 +- client/FIRE.cpp | 14 +-- client/FIRE.h | 4 +- client/LBFGS.cpp | 30 ++++--- client/LBFGS.h | 6 +- client/MinModeSaddleSearch.cpp | 5 +- client/Optimizer.h | 7 +- client/Quickmin.cpp | 12 ++- client/Quickmin.h | 4 +- client/StatusTypes.h | 154 +++++++++++++++++++++++++++++++++ client/SteepestDescent.cpp | 12 ++- client/SteepestDescent.h | 4 +- 13 files changed, 225 insertions(+), 55 deletions(-) create mode 100644 client/StatusTypes.h diff --git a/client/ConjugateGradients.cpp b/client/ConjugateGradients.cpp index 049fc7365..97cbec737 100644 --- a/client/ConjugateGradients.cpp +++ b/client/ConjugateGradients.cpp @@ -14,6 +14,8 @@ #include +using eonc::StepResult; + Eigen::VectorXd ConjugateGradients::getStep() { double a = std::fabs(m_force.dot(m_forceOld)); double b = m_forceOld.squaredNorm(); @@ -42,7 +44,7 @@ Eigen::VectorXd ConjugateGradients::getStep() { return m_direction; } -int ConjugateGradients::step(double a_maxMove) { +StepResult ConjugateGradients::step(double a_maxMove) { // Bail out instead of looping forever when the potential returns // NaN forces (atom overlap inside an EAM/ML repulsive core, etc.). // NaN propagates through dot products and < comparisons silently; @@ -52,18 +54,16 @@ int ConjugateGradients::step(double a_maxMove) { QUILL_LOG_WARNING(m_log, "[CG] non-finite force entering step (NaN or Inf); " "aborting minimization"); - return -1; + return StepResult::Failed; } - bool converged; + bool converged = false; if (m_optConfig.opts.cg.line_search) { converged = line_search(a_maxMove); } else { converged = single_step(a_maxMove); } - if (converged) - return 1; - return 0; + return converged ?

Replace the magic-int saddle-search status with a strongly-typed `enum class SaddleStatus : int` defined in StatusTypes.h alongside StepResult. API surface: client/SaddleSearchMethod.h virtual SaddleStatus run() = 0; virtual SaddleStatus getStatus() const { return SaddleStatus::Good; } virtual std::string_view describeStatus(SaddleStatus) const { return statusMessage(s); } // default forwards to canonical // statusMessage in StatusTypes.h Subclasses (MinMode / ARTn / BasinHopping / DynamicsSaddle / BGSD): SaddleStatus run() override; SaddleStatus getStatus() const override { return status; } SaddleStatus status{SaddleStatus::Good}; Job drivers (SaddleSearchJob / ProcessSearchJob): SaddleStatus do{Saddle,Process}Search(); void saveData(SaddleStatus status); void printEndState(SaddleStatus status); Migration notes: * MinModeSaddleSearch::Status (the unscoped enum with 22 STATUS_* enumerators) goes away entirely; canonical definition is eonc::SaddleStatus in StatusTypes.h. The old 22 names migrate 1:1 (STATUS_GOOD -> SaddleStatus::Good, STATUS_BAD_NO_CONVEX -> SaddleStatus::BadNoConvex, ...) preserving the underlying int values byte-for-byte so results.dat parsers, the akmc.py driver, and the JobIntegrationTest fixtures continue to read the same integers via to_int(SaddleStatus). * ARTnSaddleSearch's static constexpr int STATUS_BAD_ARTN_ERROR = 22 (and Status_Good / BadMaxIterations) are gone; ARTn now returns SaddleStatus::BadArtnError directly. The ad-hoc describeStatus override is dropped -- the base default describeStatus(SaddleStatus) -> statusMessage(SaddleStatus) handles the full vocabulary. * NEBOcinebController::runDimer keeps its own int return values (-2 / -1 / 0 / 1) since they're MMF-internal control flags with semantics distinct from saddle-search status; that subset is a candidate for its own typed enum in a follow-up. * Termination-reason serialization uses to_int(status) so the int written to results.dat is unchanged. 110+ STATUS_* call sites migrated mechanically via sed. clang-format pass applied;

Five buckets: 1. bugprone-implicit-widening-of-multiplication-result (ARTnSaddleSearch.cpp) Anchor `nat * 3` chains in size_t / ptrdiff_t up front: const std::size_t natz = static_cast(nat); std::vector if_pos(natz * 3, 1); Pointer-offset arithmetic on tau_sad_ptr / evec_ptr is now `evec_ptr + static_cast(3) * nat`. 2. performance-unnecessary-value-param (BasinHoppingSaddleSearch / BiasedGradientSquaredDescent / DynamicsSaddleSearch / ARTnSaddleSearch ctors; DynamicsSaddleSearch::refineTransition::prod) shared_ptr-by-value -> const-ref where the param is just read, pass-by-value-and-std::move where it gets stored. ARTn ctor reorders the member init list to match declaration order (avoids the -Wreorder follow-on warning). 3. bugprone-incorrect-roundings (DynamicsSaddleSearch.cpp:93,97) `(int)(x + 0.5)` is broken for negative arguments and exact floats. Replace with std::lround. 4. New typed enum MMFStatus (NEBOcinebController.h/.cpp) The runDimer return values (-2 / -1 / 0 / 1) had distinct semantic meanings (PositiveCurvature / Skipped / Helped / MaxIterations) that didn't map onto SaddleStatus -- positive curvature on the climbing image is an *expected* short-circuit for the OCINEB controller, not a generic saddle-search failure. Promote to its own scoped enum: enum class MMFStatus : int { Helped = 0, MaxIterations = 1, Skipped = -1, PositiveCurvature = -2 }; to_int(MMFStatus) for the log format strings; underlying values preserved. 5.

The Python orchestrator was still comparing raw ints (`termination_reason == 0`, `== 15`, `= 9`, `= 6`) against magic literals and carrying two duplicated label tables -- one title-cased in akmcstate.py, one slug-cased in explorer.py. Both tables had drifted out of sync with the C++ enumeration. Introduce eon/status_codes.py as the single source of truth: an IntEnum mirror of StatusTypes.h plus label / slug lookup helpers. Wire format is unchanged -- IntEnum members compare equal to the int they wrap, so existing results.dat files round-trip without churn -- but every server-side comparison now reads as the named member. Two latent bugs surface and get fixed by the consolidation: - akmcstate.py:599 had a 20-entry result_state_code list, so any termination_reason in {20, 21, 22} (DimerLostMode, DimerRestoredBest, BadArtnError -- all live status codes since the ARTn / dimer warm-start work landed) would IndexError out of register_bad_saddle and crash the akmc loop. The new helper falls back to "Unknown termination code (N)" for any value SaddleStatus cannot construct. - explorer.py:584 had "nonlocal abort" with a space (typo) where every other slug uses snake_case. Nothing downstream consumed the typo'd form, so the fix is just collapsing to "nonlocal_abort". Net cleanup: - eon/akmcstate.py: 20-line label table -> 1 helper call, `== 15` -> `== SaddleStatus.BadMdTrajectoryTooShort`. - eon/basinhopping.py:251 `== 0` -> `== SaddleStatus.Good`. - eon/explorer.py: slug table replaced by callable dispatch into saddle_status_slug / minimization_status_slug; magic-int writes `= 9` / `= 6` -> `= int(SaddleStatus.BadMinima)` / `BadNotConnected`; three `== 0` checks named.

The base-class signature changed to `SaddleStatus run() = 0`, but the unit test was never updated and the test target wasn't part of the cosmolab build, so this didn't surface locally. Adds `#include "StatusTypes.h"` + namespace-scoped `using eonc::SaddleStatus`, retypes `status` as `SaddleStatus`. The existing `>= Good` / `<= DimerRestoredBest` / `!= Good` comparisons compile cleanly because C++20 scoped-enum relational operators are well-defined within a single enum type. 2. .github/workflows/ci_docs.yml -- the `pixi run ensure_cbindgen` step was kept after commit ee27bba9 dropped that pixi task with the readcon v0.9.0 bump (cargo-c handles header generation now). Pixi exits 127 ("Available tasks: gen-ref / makedocs / ...") with no ensure_cbindgen listed.

Adds inline ostream insertion overloads in StatusTypes.h: SaddleStatus -> " ()" StepResult -> "" Then finishes the test-side migration: * OptimizerTest: 4 sites, `int status = opt.run(...)` becomes `StepResult status = opt.run(...)`; `CHECK(status == 1)` becomes `CHECK(status == StepResult::Converged)`. * ARTnTest: `int dimerStatus / artnStatus / status` -> `SaddleStatus`, the loose `>= 0` becomes `>= SaddleStatus::Good`. Adds `using eonc::SaddleStatus`. * JobIntegrationTest: 8 sites that read `int status = std::stoi(results["termination_reason"])` and then compared against `SaddleStatus::*`. `std::stoi` is the wire-format reader (results.dat carries an int), so we cast through to keep the wire side honest: `SaddleStatus status = static_cast(std::stoi(...))`. Then 5 `REQUIRE(status == 0)` and `(status == 0) // GOOD` sites become `REQUIRE(status == SaddleStatus::Good)`. The pre-existing `REQUIRE(std::stoi(results[...]) == 0)` form (no intermediate variable, comparing two ints) is left as-is -- it documents the wire-format check. Cosmolab full-tree build now green: 0 errors, 0 warnings. Runtime tests pass except `test_ira` and `test_jobs` cases that require libira / libartn on LD_LIBRARY_PATH (the dev-lite env on cosmolab does not stage them, the CI runners do). --- client/StatusTypes.h | 14 +++++++++ client/unit_tests/ARTnTest.cpp | 13 +++++---- client/unit_tests/JobIntegrationTest.cpp | 37 +++++++++++++++--------- client/unit_tests/OptimizerTest.cpp | 19 +++++++----- 4 files changed, 57 insertions(+), 26 deletions(-) diff --git a/client/StatusTypes.h b/client/StatusTypes.h index 2a7003688..95aed28b4 100644 --- a/client/StatusTypes.h +++ b/client/StatusTypes.h @@ -28,6 +28,7 @@ /// strings, JSON, saved fixture files); use magic_enum::enum_name() /// for the symbolic name in logs. +#include #include namespace eonc { @@ -151,4 +152,17 @@ enum class SaddleStatus : int { return statusMessage(static_cast(status)); } +/// Stream insertion overloads.

Affected test cases: - IRATest: 5 TEST_CASE_METHOD blocks (every match/symmetry case). - JobIntegrationTest: "SaddleSearchJob standalone ARTn works without direction file" -- the other ARTn integration cases at lines 1028 and 1091 already had the guard, this one was missed during 092e... when ARTn went runtime-loaded. linux-64 dev-mta CI passes today because the runner happens to have libira / libartn on LD_LIBRARY_PATH; the SKIP path keeps the macos build green without weakening the linux assertions. --- client/unit_tests/IRATest.cpp | 11 +++++++++++ client/unit_tests/JobIntegrationTest.cpp | 2 ++ 2 files changed, 13 insertions(+) diff --git a/client/unit_tests/IRATest.cpp b/client/unit_tests/IRATest.cpp index 9ec9e006f..88a62003b 100644 --- a/client/unit_tests/IRATest.cpp +++ b/client/unit_tests/IRATest.cpp @@ -19,6 +19,7 @@ #include "Matter.h" #include "TestUtils.hpp" #include "catch2/catch_amalgamated.hpp" +#include "libs/IRA/IRAResource.h" namespace tests { @@ -48,6 +49,8 @@ class IRAFixture { TEST_CASE_METHOD(IRAFixture, "IRA match of identical structures returns zero distance", "[ira][match]") { + if (!eonc::get_ira_resource().is_loaded()) + SKIP("libira not available at runtime"); auto result = eonc::IRACompare::match(*m1, *m2, 1.0); REQUIRE(result.error == 0); @@ -60,6 +63,8 @@ TEST_CASE_METHOD(IRAFixture, TEST_CASE_METHOD(IRAFixture, "IRA match of translated structure recovers translation", "[ira][match]") { + if (!eonc::get_ira_resource().is_loaded()) + SKIP("libira not available at runtime"); // Translate m2 by a known vector Eigen::Vector3d shift(1.5, -0.7, 0.3); auto pos = m2->getPositions(); @@ -78,6 +83,8 @@ TEST_CASE_METHOD(IRAFixture, TEST_CASE_METHOD(IRAFixture, "IRA match of permuted structure finds permutation", "[ira][match]") { + if (!eonc::get_ira_resource().is_loaded()) + SKIP("libira not available at runtime"); // Swap atoms 0 and 1 in m2 auto pos = m2->getPositions(); auto row0 = pos.row(0).eval(); @@ -97,6 +104,8 @@ TEST_CASE_METHOD(IRAFixture, TEST_CASE_METHOD(IRAFixture, "IRA match of different structures returns nonzero distance", "[ira][match]") { + if (!eonc::get_ira_resource().is_loaded()) + SKIP("libira not available at runtime"); // Displace atom 0 significantly auto pos = m2->getPositions(); pos(0, 0) += 3.0; @@ -111,6 +120,8 @@ TEST_CASE_METHOD(IRAFixture, TEST_CASE_METHOD(IRAFixture, "IRA findSymmetry returns valid point group", "[ira][symmetry]") { + if (!eonc::get_ira_resource().is_loaded()) + SKIP("libira not available at runtime"); auto result = eonc::IRACompare::findSymmetry(*m1, 0.1); REQUIRE(result.error == 0); diff --git a/client/unit_tests/JobIntegrationTest.cpp b/client/unit_tests/JobIntegrationTest.cpp index 00cbd3cf2..a6e6f7030 100644 --- a/client/unit_tests/JobIntegrationTest.cpp +++ b/client/unit_tests/JobIntegrationTest.cpp @@ -1151,6 +1151,8 @@ max_spawns = 5 TEST_CASE_METHOD(JobIntegrationFixture, "SaddleSearchJob standalone ARTn works without direction file", "[job][saddle_search][artn][optional-mode][integration]") { + if (!eonc::get_artn_resource().is_loaded()) + SKIP("libartn not available at runtime"); copyTestData("../saddle_search"); std::filesystem::remove(workdir / "direction.dat"); std::filesystem::remove(workdir / "displacement.con"); From 5ca562f5c752b66ce339471f06cda71385dbb4bd Mon Sep 17 00:00:00 2001 From: Rohit Goswami Date: Sun, 10 May 2026 16:21:59 +0200 Subject: [PATCH 50/59] chore(deps): bump readcon to v0.10.0 (energies section, atom_id index, NumPy ndarray views, zstd) --- pixi.toml | 2 +- pyproject.toml | 2 +- 2 files changed, 2 insertions(+), 2 deletions(-) diff --git a/pixi.toml b/pixi.toml index d7bd28f5d..f1251ce26 100644 --- a/pixi.toml +++ b/pixi.toml @@ -35,7 +35,7 @@ rust = ">=1.88" [pypi-dependencies] towncrier = ">=25.8.0, <26" -readcon = ">=0.9.0, <0.10" +readcon = ">=0.10.0, <0.11" [pypi-options] # TODO(rg): only if the CPU version is needed diff --git a/pyproject.toml b/pyproject.toml index fa1f27aa8..4583ededb 100644 --- a/pyproject.toml +++ b/pyproject.toml @@ -7,7 +7,7 @@ authors = [ ] dependencies = [ "numpy>=1.26.4", - "readcon>=0.9.0", + "readcon>=0.10.0", ] requires-python = ">=3.11" # readme = "readme.md" From fc1005dbe1da508c647a86294365e2087b4d018e Mon Sep 17 00:00:00 2001 From: Rohit Goswami Date: Sun, 10 May 2026 16:39:10 +0200 Subject: [PATCH 51/59] fix(loader): leak dlopen'd handles at process exit; do not dlclose in dtors XtbLoader::~XtbLoader() / LammpsLoader::~LammpsLoader() / ARTnResource::~ARTnResource() / IRAResource::~IRAResource() each held a process-lifetime dlopen'd handle and called dynlib::close() at static destruction. That ordering crashes on the ubuntu-22.04 ci-xtb runner (test_xtb / test_cineb_xtb SIGSEGV right after Catch2 prints "All tests passed", before exit). It does not crash on cosmolab dev-xtb (release or debugoptimized) because the libstdc++ / glibc destructor ordering happens to land elsewhere. Reproducing on every CI runner is not the bar; leaking the handle is the right move regardless. Why: each of these libraries (libxtb, liblammps, libartn, libira) drags in either a gfortran runtime (atexit hooks running FINAL/STOP, stdio flush) or an MPI / OpenMP / KIM teardown chain whose ordering relative to a Meyer-singleton dtor is unspecified. dlclose-during-process-fini runs those chains against a partially torn-down process state; the canonical symptom is a segfault inside libgfortran's stop_string or inside libc's stdio flush. Plugin loaders in long-lived processes (LAMMPS, GROMACS, i-PI) all leak their dlopen'd handles for the same reason -- the OS unmaps the mapping at exit, so the "leak" is bounded by process lifetime. The error-path dlclose inside the *constructor* is kept: that fires before any consumer has dlsym'd or held a function pointer, so it is safe to unwind. --- client/potentials/XTBPot/XtbLoader.cpp | 11 +- pixi.lock | 138 ++++++++++++------------- 2 files changed, 79 insertions(+), 70 deletions(-) diff --git a/client/potentials/XTBPot/XtbLoader.cpp b/client/potentials/XTBPot/XtbLoader.cpp index cec790a58..e076583d0 100644 --- a/client/potentials/XTBPot/XtbLoader.cpp +++ b/client/potentials/XTBPot/XtbLoader.cpp @@ -88,7 +88,16 @@ XtbLoader::XtbLoader() { m_loaded = true; } -XtbLoader::~XtbLoader() { dynlib::close(m_handle); } +XtbLoader::~XtbLoader() { + // Intentionally do NOT dlclose at static destruction. libxtb pulls in + // the gfortran runtime, which installs its own atexit / __attribute__ + // ((destructor)) hooks that depend on stdio + global state that is + // already being torn down by the time this Meyer-singleton dtor runs. + // dlclose-then-Fortran-fini-during-process-shutdown crashes on the + // Linux GHA runner (test_xtb / test_cineb_xtb SIGSEGV after all + // assertions pass).

The guard is the right behaviour but the implementation called `m_objf->getGradient()` afresh at three of the four sites: LBFGS::run end: if (!m_objf->getGradient().allFinite()) ... CG::step entry: if (!m_objf->getGradient().allFinite()) ... CG::run end: if (!m_objf->getGradient().allFinite()) ... Each fresh getGradient invalidates the cached forces the saddle-search outer loop just populated, charging +1 force evaluation per call. On SaddleSearch / morse_pt the end-to-end cost was a 28 - 39% regression (39 -> 50 force calls dimer, 44 -> 61 Lanczos), exactly the JobIntegrationTest "force calls match SVN" assertions tripped on the macos / ubuntu CI runs of #338. Bisected by reverting the four checks on cosmolab and watching the SVN bounds satisfy. Trim to one cached check per optimizer: * LBFGS::step keeps `if (!f.allFinite())` -- `f` is the local already loaded by `f = -m_objf->getGradient()` at the top of step() so the check is free. The exit-side fresh getGradient in LBFGS::run goes. * CG::step gates the check on `m_cg_i > 0` and uses the stored `m_force` from the previous step's line_search / single_step body. No fresh evaluation, so the saddle-search cache stays warm. The exit-side fresh getGradient in CG::run goes. The per-step guard is sufficient: if NaN appears between steps, the next step()'s body still loads it via getGradient and the guard fires there; if NaN appears mid-step, the local-`f` / local-`m_force` check inside the body bails on the same iteration. Validated on cosmolab dev-lite (`meson test test_jobs`): all SaddleSearch SVN bounds satisfied (1/1 PASS). --- client/ConjugateGradients.cpp | 19 ++++++++++--------- client/LBFGS.cpp | 17 ++++++++--------- 2 files changed, 18 insertions(+), 18 deletions(-) diff --git a/client/ConjugateGradients.cpp b/client/ConjugateGradients.cpp index 97cbec737..e2c21d509 100644 --- a/client/ConjugateGradients.cpp +++ b/client/ConjugateGradients.cpp @@ -45,12 +45,14 @@ Eigen::VectorXd ConjugateGradients::getStep() { } StepResult ConjugateGradients::step(double a_maxMove) { - // Bail out instead of looping forever when the potential returns - // NaN forces (atom overlap inside an EAM/ML repulsive core, etc.). - // NaN propagates through dot products and < comparisons silently; - // without this guard line_search keeps shrinking the step and never - // exits because isConverged() never sees a finite-norm check. - if (!m_objf->getGradient().allFinite()) { + // Non-finite check: use the previous step's stored m_force (set by + // single_step / line_search) rather than calling getGradient() + // afresh.

Catch2 amalgamated as a single static_library `thirdparty/catch2/catch_amalgamated.cpp` (~3000 lines including ) was listed in every test executable's `sources`, so each of the 30+ test targets re-compiled it from scratch. Under ASan + UBSan instrumentation that's the dominant cost of the sanitizer build (45+ min observed on the GHA ubuntu runner; the in-progress step that prompted the ask). Promote it to its own `static_library('catch2_amalgamated', ...)` and link the artifact into every test exe + the TestMain helper + the nwchem socket exe + bench_pot. Catch2 compiles once per build dir per buildtype. Side benefit: the lib is built with `-Wno-maybe-uninitialized`, suppressing the libstdc++ 13.3 false positive on `function` move-ctor inside `_NFA::_M_insert_alt` that fires only at -O3 + LTO (the release-buildtype CI matrix). This is the long-running GCC PR93499 / 96012 family. eOn's own test sources stay under -Wmaybe-uninitialized. 2. bench_pot off the default-build set `bench_pot` is the meson benchmark target invoked by `meson test --benchmark`. The default `meson compile` builds it too, which is wasted work in: - sanitizer matrix (instruments + links a benchmark binary nobody runs in `meson test --suite eon`) - test matrix (same; benchmarks have their own job) - dev-loop (anyone who ran `ninja -C bbdir`) `build_by_default = false` keeps `meson test --benchmark` and any explicit `ninja bench_pot` working but skips it from the default target set. That alone trims ~20% off the sanitizer build wall.

The dedup works at debug / debugoptimized buildtypes (cosmolab green), but at the CI's `--buildtype release` (which sets `-flto=auto`) LTO sees through the archive boundary and prunes any object whose symbols aren't directly referenced by the test source. That includes the Catch2-amalgamated `main()` -- no test source calls main, so LTO drops it -- and the AssertionHandler / EventListener vtable carriers for the listener that TestMain.cpp registers. Result: every test linker step blew up with (.text+0x24): undefined reference to `main' undefined reference to `Catch::AssertionHandler::handleExpr(...)' undefined reference to `Catch::EventListenerBase::testRunStarting(...)' ... Switch from `link_with: catch2_lib` to `link_whole: catch2_lib` everywhere catch2_lib is consumed (test executables foreach, test_socket_nwchem, bench_pot). `link_whole` translates to `-Wl,--whole-archive` which forces the linker to pull in every object before LTO runs, so main() and the listener machinery survive the LTO pass. The size cost is bounded by the catch2 amalgamated itself (~250 KiB per exe at -O3 -flto), which is the same cost the pre-d60a9b80 per-target compile already paid.

Local cosmolab dev-lite at `--buildtype release`: still 0 errors, 0 warnings -- the GCC build still gets the suppression and the catch2 amalgamated still compiles cleanly. --- client/meson.build | 9 ++++++++- 1 file changed, 8 insertions(+), 1 deletion(-) diff --git a/client/meson.build b/client/meson.build index 015e29f52..61a31e2bf 100644 --- a/client/meson.build +++ b/client/meson.build @@ -1013,11 +1013,18 @@ if get_option('with_tests') # bug-family (PR93499 / 96012).

Conda-forge's clang 19 toolchain on Windows makes meson's `static_library` emit a GNU `.a` archive, but the MSVC link.exe `/WHOLEARCHIVE` flag expects a COFF `.lib`. The two formats are not interchangeable. Branch the meson logic on `host_machine.system() == 'windows'`. Linux and macOS keep the catch2_lib + link_whole path (the sanitizer-time win that prompted d60a9b80). Windows reverts to the pre-d60a9b80 behaviour: catch_amalgamated.cpp is added to each test executable's sources directly. The cost is one extra compile per test target on the single Windows matrix entry; the Windows builds are not the slow ones. Verified on cosmolab dev-lite at `--buildtype release` (matches CI flags): all 390 targets link clean. --- client/meson.build | 67 +++++++++++++++++++++++++++------------------- 1 file changed, 40 insertions(+), 27 deletions(-) diff --git a/client/meson.build b/client/meson.build index 61a31e2bf..48db606c6 100644 --- a/client/meson.build +++ b/client/meson.build @@ -1005,27 +1005,38 @@ endif if get_option('with_tests') test_args = _args test_deps = _exe_deps - # Catch2 amalgamated pulls in ; libstdc++ 13.3 std::regex - # move-ctors trip a -Wmaybe-uninitialized false positive at -O3 + LTO - # (release buildtype) because the optimizer inlines the function<> - # move-ctor into _NFA::_M_insert_alt before it can prove _M_invoker / - # _M_manager are initialized by the default ctor.
