Agenda

  • updates to GitHub integration (--new-pr, --update-pr)
  • support for using ccache/f90cache
  • support for eb --install-latest-eb-release
  • running individual tests
  • task force for (experimental) RPATH support
  • Q&A

Notes

  • bug that prevents use of --install-latest-eb-release in hierarchical MNS

  • filtering of tests with regex

    • update docs

  • ccache support is a good starting point

  • EasyBuild v2.9.0: https://github.com/hpcugent/easybuild/issues/219

  • Kenneth & Robert: sprint for RPATH support

  • easyblock to support installing X11 stack behind a single module

    • Alan: issue with jhbuild: doesn't seem to work with custom Python module (mako)
      • also supports building partial X stack
      • TODO Alan: PR for jhbuild easyconfig + issue for problems with using jhbuild to install X stack
    • other idea is to install X libs as bundle as 'extensions' where ConfigureMake is used as an easyblock for the extensions

  • Alan: towards 'fat' .yeb easyconfigs

    • only in one dimensions: multiple toolchains in a single .yeb
    • TODO:

      • syntax of listing support for multiple toolchains

        • figure out what is supported
        • one quick way would be to expand a .yeb into multiple .eb's in a temporary directory via .dump()

      • support on the 'eb' command line

        • "eb CMake-3.5.1.yeb" => how to specify toolchain?
        • --toolchain=intel,2016a # also consider subtoolchains
        • interactive CLI + override option: "eb CMake-3.5.1.yeb GCC,4.9.4"
        • "eb CMake.yeb" => version, toolchain, versionsuffix
          • "eb CMake 3.5.1 GCC,4.9.4", "eb CMake GCC,4.9.4"

      • also relates to --minimal-toolchains: http://easybuild.readthedocs.io/en/latest/Manipulating_dependencies.html#using-minimal-toolchains-for-dependencies

  • Pablo: problems with dry-run & hidden modules

    • Damian: no problem at JSC...
    • Pablo will open an issue
    • Fotis: relative paths in $MODULEPATH may cause issues like this
