Agenda

Notes

RHEL 7.3 incompatible with intel/2016b installations
  • also happens on Ubuntu 16.04
  • issue with libintlc.so.5 in Intel PSXE 2016.3 and 2016.4
  • copying this library from PSXE 2017.1 into 2016.3 seems to fix the problem (but is this OK?)
  • recompiling on RHEL 7.3 with 2016.3 doesn't fix this, still segfaults
  • Kenneth contacted Ben Woodard on LLNL w.r.t. suggested workaround from Intel support
  • Damian: JSC can open Intel support ticket too on this issue?
  • Rob: also contact TACC?
  • [update 20170119] Intel published an article where copying libintlc.so.5 is a confirmed proper workaround, see https://software.intel.com/en-us/articles/intel-compiler-version-16-not-compatible-with-recent-libcso6
2017a toolchains

  • foss/2017a WIP PR: https://github.com/hpcugent/easybuild-easyconfigs/pull/3968

    • still on hold for OpenMPI 2.0.2...

  • intel/2017a WIP PR: https://github.com/hpcugent/easybuild-easyconfigs/pull/3969

    • install Intel PSXE 2017.x as a whole rather than as individual components (icc, ifort, impi, imkl)
    • impact on hierarchical module naming schemes?
      • still need icc/ifort separately anyway if Intel compilers are combined with other MPI/LAPACK libs
      • intel module in HMNS with PSXE installed a whole would expand both Compiler and MPI module subtrees
    • requires changes in framework w.r.t. intel toolchain definition, maybe also custom easyblock for intel-psxe
    • custom easyblock needed for Intel PSXE with proper sanity check
    • specify components so only icc/ifort/impi/imkl
    • also ITAC, IPP, etc. would be included in PSXE install?
EasyBuild v3.1.0
  • ETA last week Jan'17
    • anything ready by then will be included
  • no v3.0.3 release
    • FFTW easyblock is considered too 'big' to include in bugfix release
Other
  • Shahzeb: some trouble with getting Intel Python with IntelBase
    • Damian: some benchmarks on GCC vs Intel build of Python showed recently, were on par (excl. numpy/scipy)
  • EasyBuild User Meeting: recording/streaming?
    • Alan: recording should work, streaming may be possible (but slightly delayed since it passes via YouTube)
    • tour of facilities?
      • would everyone join or would group be smaller?
