2017b toolchains

• GCC 6.4.0 is good to go https://github.com/easybuilders/easybuild-easyconfigs/pull/4794
• foss/2017b https://github.com/easybuilders/easybuild-easyconfigs/pull/4768
  • on hold OpenBLAS 0.2.20
• intel/2017b
  • good to go, but should be released in sync with foss
• not EB v3.3.1

EasyBuild v3.3.1

• will include fix for --new-pr: change default target (https://github.com/easybuilders/easybuild-framework/pull/2258)
• also some other minor fixes/updates:
  • framework: https://github.com/easybuilders/easybuild-framework/milestone/49?closed=1
  • easyblocks: https://github.com/easybuilders/easybuild-easyblocks/milestone/41?closed=1
  • easyconfigs: https://github.com/easybuilders/easybuild-easyconfigs/milestone/44?closed=1

Migration to github.com/easybuilders

• Damian: eb --install-latest-eb-release still works: good!
• only real issue is --new-pr got broken
  • will be fixed by https://github.com/easybuilders/easybuild-framework/pull/2258
  • workaround for now: use eb --pr-target-account=easybuilders --new-pr
• redirect for website needed to be put in place
  • see https://github.com/hpcugent/hpcugent.github.com/pull/3

Maintainers

• PR to update docs: https://github.com/easybuilders/easybuild/pull/350
• 8 maintainers now, spread across different repositories
• see http://easybuild.readthedocs.io/en/develop/Maintainers.html (once docs PR is merged)
• assigning write permissions via teams in github.com/easybuilders isn't working?!
• TODO: figure out labels to organise issues/PRs better...

Host for next conf calls?

• Wed July 19th 2017: will hosted by Damian
• Wed Aug 2nd 2017: will hosted by Davide

Other

• Damian: looking into making JSC repo public under github.com/easybuilders

  • first cleaning it up and internal checking
  • Damian has required rights to host it under github.com/easybuilders
  • will be maintained by Alan & Damian
  • pretty much in sync with JSC internal repo
  • some do require modifications to easyblocks
    • also making that available can be considered
  • could serve as inspiration for others, e.g. on HMNS
  • see also CSCS repo at https://github.com/eth-cscs/production

• Davide: work on fosscuda toolchain

  • see https://github.com/easybuilders/easybuild-framework/pull/2253
  • problem with GCCcore-CUDA in $MODULEPATH?
    • see det_modpath_extensions in HMNS, needs to be made aware of GCCcore+CUDA combo
    • both GCCcore-CUDA & GCC-CUDA subdirs should be added to $MODULEPATH for gcccuda & iccifortcuda toolchain/module
    • see test_hierarchical_mns to evaluate changes with breaking backward compatibility
  • using GCCcore-CUDA allows sharing installations between fosscuda and intelcuda
  • Shahzeb: problems building with GCCcore
    • probably missing binutils build dep?

• interest from Singularity community to add support in EasyBuild for generating Singularity images

  • can be done in a number of ways, options need to be figured out and evaluated
  • Kenneth/Pablo have a conf call planned with Rstor (company supporting Singularity) on this subject
