Why do my jobs on gpu_p5 partition fail with "Illegal Instruction" error?

This error indicates that you have used modules or code incompatible with the AMD CPUs equipping this partition gpu_p5.

Unlike all of other Jean Zay's nodes which are equipped with Intel CPUs, the nodes in this partition are equipped with AMD CPUs, which has two consequences:

  1. The modules accessible by default (module avail) are not compatible with this partition. It is necessary to first load the cpuarch/amd module (module load cpuarch/amd then module avail) to be able to list and load the compatible modules.
  2. You also need to recompile your codes for AMD CPUs using compatible modules.

You can consult the documentation Modules compatible with the gpu_p5 partition for more information.
