Multi-module Adaptation With WASL

This repo contains source code and other artifacts related to the paper WASL: Harmonizing Uncoordinated Adaptive Modules in Multi-Tenant Cloud Systems. WASL is a rate-adaptation based technique for runtime cross-layer coordination in multi-tenant clouds to mitigate performance interference arising due to multiple colocated adaptive applications.

DOI Reference: Zenodo

TailBench applications have been used for evaluation. Tailbench details are here.
TailBench : Updates to standard TailBench suite used for experiments

The SetUp instructions are available here.
