  • intel:
    • compilers: 2020 update 3 (Aug 21st 2020)
    • MPI: 2019 update 8 (Jul 15th 2020)
    • MKL: 2020 update 3 (Sept 1st 2020)
    • is GCC 10.x supported officially as base compiler?
      • strictly according to release notes: no => "gcc 4.8.5 to gcc 9.0.1" and "binutils 2.27 to binutils 2.31.1", but that seems very conservative
      • Kenneth has contacted Intel guy, no reply yet...
  • recent progress:

  • Python

  • close to 400 easyconfig PRs in flight currently...
  • time for another merge sprint
    • focused on oldest PRs: close or get them merged
    • we should not forget to ensure a fresh CI run is done first!
  • Kenneth will set a date for this (Wed in non-conf-call week)
