Overview of recent changes included in EasyBuild v4.2.0

Update on 2020a common toolchains

  • see project dashboard: , and see also the 2020a branch and milestone
  • foss/2020a
    • GCC 9.3.0 + binutils 2.34
    • OpenMPI 4.0.3
    • OpenBLAS 0.3.9
    • ScaLAPACK 2.1.0
    • FFTW 3.3.8
  • intel/2020a
  • not compatible CUDA yet, so fosscuda/2020a on hold
  • TODO:
    • figure out what to do with impi 2019 update 6/7
    • more testing with (updated) intel/2020a
    • collapse 2020a branch into develop
      • gradually: first GCCcore-9.3.0 easyconfigs, then foss/2020a
      • ensure PRs to develop branch can be re-tested (so not too many easyconfigs in a single PR)
    • potential way forward is to only collapse foss/2020a into develop, put intel/2020a on hold...
    • figure out how to get rid of 2020a branch, what to do with open PRs to 2020a?

Q&A

  • Pablo: GCC + OpenMPI GPU offloading
    • anyone else playing with this?
    • requires significant changes in GCC easyblock
    • Victor: ongoing ECP project on this to get this to work well
      • requires recent version of OpenACC
      • still some bugs
    • any docs on this?
      • only GCC docs, which are not easy to digest...
