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

  • nicely handling co-processors in HIerarchicalMNS
