Agenda

update on support for PGI as toolchain compiler
- https://github.com/hpcugent/easybuild/issues/211
outlook to EasyBuild v2.8.0 (https://github.com/hpcugent/easybuild/issues/209)

Notes

PGI toolchain, pretty much there in develop
- Markus: problems on Debian system with using PGI toolchain
  - using PGI 15.10; does it also occur with PGI 16?
  - seems related to binutils, works fine with system binutils (which is patched?)
  - related to multiarch
  - works fine with GCC-based toolchain though...
- for older PGI versions (15.x), pgc++ is not 'correct' (although it is provided), pgCC is the recommended one
  - should be fixed in pgi.py
- Rob will test PGI with MVAPICH2 + Intel MKL
  - Damian: toolchain like this is used @ JSC
    - MVAPICH2 version that is CUDA-aware is compiled with old PGI, may not work with newer PGI versions
2.8.0 roadmap
- Damian: significant speedups in dry-run & installing extensions (Perl, Python, R)
  - thanks to:
    - refactoring to avoid recreating ModulesTool instances over and over again: https://github.com/hpcugent/easybuild-framework/pull/1735
    - caching of module avail: https://github.com/hpcugent/easybuild-framework/pull/1742
- framework: https://github.com/hpcugent/easybuild-framework/milestones/v2.8.0
  - Kenneth will take a look at the bug reported by Damian w.r.t. build dependencies not being loaded when installing extensions
    - https://github.com/hpcugent/easybuild-framework/issues/1741
  - long-standard bug w.r.t. hierarchichal module naming schemes and Lua module files should be fixed (finally) too: https://github.com/hpcugent/easybuild-framework/pull/1474
  - support for CrayPGI toolchain: depends on availability of JG (CSCS)
- easyblocks: https://github.com/hpcugent/easybuild-easyblocks/milestones/v2.8.0
  - nothing major outstanding
  - change to CMakeMake easyblock to always enable -DCMAKE_BUILD_TYPE=Release is worth considering
    - https://github.com/hpcugent/easybuild-easyblocks/pull/911
  - SuiteSparse & SuperLU easyblocks: depends on availability of Xavier
    - https://github.com/hpcugent/easybuild-easyblocks/pull/863
    - https://github.com/hpcugent/easybuild-easyblocks/pull/860
  - updates to Score-P easyblock by Markus: review-ready, Kenneth will try and get this in (but not a blocker)
    - https://github.com/hpcugent/easybuild-easyblocks/pull/889
  - changes to SCOTCH easyblock w.r.t threading needs a bit more work to avoid breaking backwards compatibility
    - https://github.com/hpcugent/easybuild-easyblocks/pull/914
- easyconfigs: https://github.com/hpcugent/easybuild-easyconfigs/milestones/v2.8.0
  - nothing major outstanding, open PRs need to be revised for inclusion in v2.8.0
  - foss/intel toolchain updates got merged (candidates for 2016b toolchains):
    - intel/2016.02-GCC-5.3: https://github.com/hpcugent/easybuild-easyconfigs/pull/2523
    - intel/2016.03-GCC-5.3: https://github.com/hpcugent/easybuild-easyconfigs/pull/3009
    - foss/2016.04: https://github.com/hpcugent/easybuild-easyconfigs/pull/3013
Markus: long-standard issue with quoting and --job would be nice to resolve...
- cfr. https://github.com/hpcugent/easybuild-framework/issues/1438
- proposed fix in https://github.com/hpcugent/vsc-base/pull/151 got blocked
