Notes

EasyBuild 2.1

• documentation is already updated for v2.1, release is going to happen anytime now (certainly today)
• short overview of major features added in v2.1, see http://easybuild.readthedocs.org/en/latest/Release_notes.html

EasyBuild on Cray

• report on current status @ https://github.com/hpcugent/easybuild/wiki/EasyBuild-on-Cray
• next hackathon in Espoo (May 4-5 2015) is largely Cray-themed

Support for module properties

• properties: namespace/values (dict)
• define known properties in EasyBuild config, tell Lmod about them by generating another $LMODRC file
• keywords (non-Lmod specific), whatis
• some properties will be in easyconfig (e.g. arch, moduleclass), others will

Packaging support

• should work now, needs docs and feedback
• get in for EB v2.2 under --experimental
• support for installing FPM with EB is a prerequisite
• way in which dependencies are handled may require more flexibility to let people do what they want
• package per EB installation vs multiple EB installations in a single RPM (e.g. Szip+HDF5+netCDF @ TACC)
  • let Bundle easyblock do multiple installs by calling out to different easyblocks, then create package + module?
• TACC as a prime tester? keep under --experimental until after hackathon in Austin?
  • already requests received to support EB @ TACC

DB support for tracking module usage in Lmod

• via a dedicated hook
• • accompanying analysis tools
