Overview of recent changes

• next release ETA: sometime during the week of Mar 9-13
  • probably v4.2.0 because of changes in framework
• Framework: https://github.com/easybuilders/easybuild-framework/milestone/75
  • https://github.com/easybuilders/easybuild-framework/pull/2599 by Alan O'Cais stands out as a big change which is a good reason to call it 4.2.0.
• Easyblocks: https://github.com/easybuilders/easybuild-easyblocks/milestone/64
  • https://github.com/easybuilders/easybuild-easyblocks/pull/1933 is another good reason
• Easyconfigs: https://github.com/easybuilders/easybuild-easyconfigs/milestone/67
  • Lots of small updates as usual.

2020a common toolchains

• see project dashboard: https://github.com/orgs/easybuilders/projects/2, and see also the 2020a branch and milestone: https://github.com/easybuilders/easybuild-easyconfigs/milestone/68
• foss/2020a
  • GCC 9.2.0 + binutils 2.32 (maybe bump to GCC 9.3 if it's available soon?) March 12 perhaps
  • OpenMPI 4.0.3 (soon, see https://github.com/open-mpi/ompi/milestone/52) now rc4 is out since Feb 27 (NOTE: 4.0.3 was released a few hours after the conf call)
  • OpenBLAS 0.3.8
  • ScaLAPACK 2.1.0
  • FFTW 3.3.8
• intel/2020a
  • based on GCC 9.2.0 + binutils 2.32 (maybe GCC 9.3?)
  • iccifort 2020.0.166 (a.k.a. 2020 initial, v19.1)
  • impi 2019.6.199
  • imkl 2020.0.166
• merge sprint to kickstart 2020a generation of easyconfigs using temporary version of foss/2020a and intel/2020a (using release candidate for OpenMPI 4.0.3?)
  • to be planned (doodle), maybe 2nd week of March? Caspar says he will take of that.
• Bart: CUDA 10.2 easyconfig may be incompatible

Q&A

• Alex: Are we going to wait for OpenMPI 4.0.3? Bart: I would say yes for the final toolchain, not for the initial generation of easyconfigs. NOTE: released very soon after
