• PGI support: https://github.com/hpcugent/easybuild/issues/211

  • Damian: using PGI (+MVAPICH2 2.2b GDR) has worked out quite well (HDF5, netCDF (serial + parallel), ...)
    • problem with building GMP with PGI, requires precise
      • use strict instead?

• Adam: PRs for older versions?

• Damian: build deps are not loaded when installing extensions?!

  • ld.gold was being picked up from system during installation of Perl modules

• Fotis: module use gets undone when new bash shell is started on some systems

  • module use /foo
  • echo $MODULEPATH
  • bash
  • echo $MODULEPATH

• Fotis: defining $MODULEPATH based on group membership?

  • Alan: yes, via profile script
  • Fotis: relying on id?
  • performance issues when 'module use/unuse' is used...

• use of group easyconfig parameter, what's the need for the os.setgid call in use_group function?

  • group ownership is also correct without the os.setgid call?

• --subdir-user-modules doesn't work as intended? no documentation available?
