EasyBuild @ JSC (Alan)
  • EasyBuild being considered as the build tool for JUROPA4 (which will include some form of accelerators), currently in exploratory stages
  • initial EasyBuild training (last week) at JSC went well, except for a couple of hickups
  • cfr.,
  • core team is going to look into EasyBuild in the coming weeks, in preparation for the EasyBuild hackathon at JSC (Feb 19th-21st 2013)
  • it would be useful to be able to keep track of who did which build
  • (Kenneth) should become very easy once we have the support for site customizations in place, e.g., making every module set a $CONTACT environment variable
  • Alan is also looking into making the switch to Lmod, together with EasyBuild
Sharing an install target with multiple users (Alan)
  • some issues when multiple people are using EasyBuild on the same system
  • cfr., fixed for EB v1.10
  • some issues when multiple people are installing software to the same install path
  • this should be resolved with a proper umask setting
  • alternatively, EasyBuild could be made aware that software is installed by a group of people (e.g. an easybuild POSIX group), and act accordingly w.r.t. permissions
Keeping track of popular module files (Fotis)
  • open question on how people are tracking module usage
  • @ JSC: no tracking done for now
  • @ UGent: by modifying the module function definition and logging module commands to syslog
  • (Kenneth) Lmod has a proper solution for this, with hooks to make things happen when module commands are run
