Common toolchains

2021b (WIP!)

  • base: GCCcore/11.2.0
    • what about compatibility with Intel compilers?
  • merged easyconfigs PRs with GCCcore/11.2.0:
  • easyconfig for OpenMPI 4.1.1 with GCCcore/11.2.0 (#13668)
    • same OpenMPI as in foss/2021a
    • should we wait until OpenMPI 4.1.2 is released?
    • is OpenMPI 4.1.1 actually compatible with PMIx 4.x?
    • foss/2021b is important for GPU software (GCC 11.2 is officially supported in latest CUDA)
  • PR for intel/2021.07 (candidate for intel/2021b): #13639
    • unofficially, latest Intel versions should be compatible with GCC 11.2 ...

AlphaFold

  • WIP PR for AlphaFold easyconfig (foss/2020b): #13744

    • but AlphaFold doesn't seem well suited to be run CPU-only...
      • 15x speedup when running on P100 GPU (for the small_bfd dataset)
      • bfd vs small_bfd is 100x in data volume (~1.7TB vs 17GB)
    • easyconfig for required aria2 dependency merged via PR #13709
    • easyconfig for required jax dependency merged via PR #13622

  • custom easyblock for jaxlib (component in jax installation): https://github.com/easybuilders/easybuild-easyblocks/pull/2545

    • required because: uses Bazel as build tool, additional options/work needed when building with CUDA support enabled
    • corresponding (updated) jax easyconfigs (foss/2020b + fosscuda/2020b): https://github.com/easybuilders/easybuild-easyconfigs/pull/13760
      • still some trouble with the test suite
      • several tests fail, even when setting various magic environment variables to steer the tests
        • patch out the broken tests
      • trouble in multi-GPU context
      • severely overloading cores when running tests in parallel (even close to a fork bomb...)

Q&A

  • Mikael: no more releases of Qt 5.15.x
    • we should start looking into Qt6 soon-ish
    • latest bugfix releases of 5.15.x are not public...
  • Mikael: should we start having GTK2 and GTK3?
    • they seem to be compatible to have both active at the same time
  • Fotis: who was looking into GitLab integration for testing EasyBuild?
    • to enable use of --new-pr to a GitLab repository
    • it's possible to combine GitLab CI/CD to test GitHub repositories
