Meeting (2025-12-18)

Attending: Lara, Caspar, Sam, Satish

  • Replace bench_name_ci with is_ci_test https://github.com/EESSI/test-suite/pull/301/changes

    • Can be tested, pretty uncontroversial

  • Demote missing read_only_files and required_memory_per_node to warning by default, to make development easier (you just want the test to run initially) https://github.com/EESSI/test-suite/pull/302

    • Can then be promoted to error by setting --setvar on CLI, see e.g. the test.yml

  • The PRTE variable in https://github.com/EESSI/test-suite/pull/305 was tested by Caspar but didn't work. Sam will try to confirm

    • Caspar did try with the command-line option, that worked
    • Debugging output wasn't informative as to why it would be different / not working with the env var
    • Should probably send an issue upstream and ask if we're doing the right thing (documentation on this env var is non-existent)

  • https://github.com/EESSI/test-suite/pull/308 showed poor performance on full node

    • Probably due to oversubscription of cores causeing cache trashing
    • Satish noticed that thread binding helps performance
    • Caspar will call the thread binding hook

  • https://github.com/EESSI/test-suite/pull/303 LAMMPS + OBMD + ALL is still problematic / failing

    • Failures are erratic
    • Caspar noticed it did succeed if he runs interactively in an salloc
    • Caspar will look for environmet differences to see what's causing this

Two issues:
