📝 Walkthrough

Walkthrough

These changes implement explicit wheel path support in the performance testing pipeline. A new CLI option is added to specify the wheel file location, passed as an environment variable to the installation script that validates and uses the specified wheel before falling back to directory-based discovery. Additionally, a cleanup fix removes duplicate MPI arguments during script generation.

Changes

Cohort / File(s) Summary
MPI Arguments Cleanup
jenkins/L0_Test.groovy
Prunes existing --mpi=pmi2 and --mpi=pmix arguments from srunArgs before disaggregated and non-disaggregated script generation to prevent duplicates.
Wheel Path Support
jenkins/scripts/perf/local/slurm_install.sh, jenkins/scripts/perf/local/submit.py
Adds --wheel-path CLI option in submit.py and exports it as WHEEL_PATH environment variable. Installation script now validates explicit wheel path; if set and exists, uses that wheel directly; otherwise warns and falls back to build directory search.
