  • upcoming releases: EasyBuild v3.0.3, EasyBuild v3.1.0
  • long-term goals in 2017
  • Q&A

Notes

2017a toolchains
EasyBuild v3.0.3
  • minor release that includes 2017a common toolchains
EasyBuild v3.1.0
  • feature release, with (slightly) enhanced framework
Long-term goals in 2017
  • more frequent minor releases (cfr. v3.0.x)
  • (stable) support for fat .yeb easyconfigs
    • initially only fat w.r.t toolchains
    • Rob: also related to more flexible dependency resolution?
    • Alan: could help with mapping one toolchain to another, porting software stacks across multiple systems
  • better support for site-specific customisations
    • e.g., tweaking of OpenMPI configuration
  • make it easier to pick up tools/libraries from the OS
    • mostly for compilers & MPI
    • MPI because of tuning
    • compilers because they may be provided by the vendor
    • does Spack support picking up MPI libraries from the system like it does for compilers?
  • integration with Singularity
    • can be extended to other tools like Docker, Nix, etc.
    • two-fold integration:
      • build in isolation by running EasyBuild inside a container
      • use EasyBuild to create Singularity images
        • downside is that you need the toolchain in each image? maybe not...
  • Alan: support for instrumentation (e.g., Score-P)
    • implementation is similar to how ccache support is implemented?
  • stable support for RPATH
    • actually short-term, almost stable?
    • Pablo is almost using it in production
    • need to opt-out for some easyconfigs, mostly for stuff including own CMake, libraries in tarball
  • Fotis: integration with CI?
    • see work done at CSCS with Jenkins & EB
    • PROVA: https://prova.io
    • document list of use cases of how EasyBuild is leveraged
    • how to prioritise builds to speed up or deliver the critical/interesting stuff first
    • web interface to show results, e.g. CDash
Other
  • agenda for EUM should be updated to include site presentations,
  • Adam: joint effort to update common tools & libraries together with common toolchains?
    • already done for Python 2/3, Perl, R
    • wider effort for e.g. bioinformatics shortly after first EasyBuild release that includes updated common toolchains?
