detect_layout_mismatch_copies tool, a new automated graph analysis tool for identifying copy operations causing physical layout mismatch, HBM materialization, and TPU lane boundary alignment overhead.
…automated graph analysis tool for identifying copy operations causing physical layout mismatch, HBM materialization, and TPU lane boundary alignment overhead. - The tool recursively traverses the HLO instruction graph context to catch sandwiched copies between upstream and downstream compute-intensive operations, while evaluating TPU lane size alignment constraints based on raw primitive data types. - This tool is exposed via the `xprof_cli` and the MCP server to support autonomous performance profiling discovery and layout optimization workflows. - It also updates the XProf smart suggestions reference (`smart_suggestions.md`) with the matching detection specifications and JAX-level refactoring recommendations.
