During June 2024 maintenanceStarting from September 5th, 2023, Setonix will be updated to include compute nodes with the new Cray Programming Environment (CPE) 23.09 which includes newer MPI libraries and a newer Cray compiler version (16.0.1). In preparation for this, the Pawsey team has prepared the new software stack, which will be available after the maintenance via the default pawseyenv/2024.05 module03. This update to CPE will result in better performance of the supercomputer but will also imply a series of modifications and updates in the whole working environment to users. The purpose of this page is to consolidate in one place all the important points that researchers will need to pay attention, together with the recommended actions or changes to take.
