With some delay, we are finally switching over to the 2019a software stack on the legacy Broadwell and Ivybridge (incl. Sandybridge) architecture based nodes. The following partitions are affected by this change:

  • broadwell
  • gpuk20
  • gputitanrtx
  • sandybridge


If you rely on software, which is not yet included in these newer toolchains, or need to use specific versions of the older toolchains to ensure reproducible results you can still switch to the old software stack!

-----------------------------------------------------------------------------------------------------------

If (and only if!) you want to keep your old software environment, you have to use the following commands before loading any modules (in your job scripts or interactive):

On partition broadwell:

module unuse /Applic.HPC/Easybuild/broadwell/2019a/modules/all/Core
module use /Applic.HPC/broadwell/modules/all/Core

On partitions gpuk20:

module unuse /Applic.HPC/Easybuild/ivybridge/2019a/modules/all/Core
module use /Applic.HPC/k20/modules/all/Core

On partitions gputitanrtx, sandybridge:

module unuse /Applic.HPC/Easybuild/ivybridge-IB/2019a/modules/all/Core
module use /Applic.HPC/k20/modules/all/Core
