Notes

revamped EasyBuild documentation
outlook to EasyBuild v1.16.0 and v2.0
issues with HierarchicalMNS
  • Alan/Eric:

    • issue when a tool (GMP) built with another compiler (not in the toolchain) is brought in, since suddenly MPIs are being swapped by Lmod and lots of stuff is rendered inactive
    • move ‘module use’ to toolchains instead?
    • collapse compiler into GMP module to avoid extra extensions to $MODULEPATH causing problems?
  • only icc module needs to be loaded to expand $MODULEPATH and make MPI module available

    • access to (also Fortran) application modules can be obtained without ever loading the ifort module...
    • solution?
      • make ‘module use’ in icc/ifort modules conditional on companion module being loaded already?
      • can Lmod spider handle this?
    • cfr. https://github.com/hpcugent/easybuild-framework/issues/1076
  • nicely handling co-processors in HIerarchicalMNS
