cpeCray

User documentation

The cpeCray modules are the interface between EasyBuild and the HPE Cray Programming environment amd compiler module and other libraries. These modules replace the HPE Cray PrgEnv-cray module and load the precise versions required by the LUMI software stack with the same version number as the cpeCray module.

When doing development on top of libraries already installed with EasyBuild in the LUMI stack, users should use the cpeCray module rather than the PrgEnv-cray module and the latter will be removed from the environment anyway as soon as the cpeCray module is loaded, e.g., as a dependency of a library build with EasyBuild in the cpeCray toolchain.

Note that the cpeCray toolchain is for CPU and GPU programming. For GPU programming, the rocm module also needs to be loaded.

Pre-installed modules (and EasyConfigs)

To access module help and find out for which stacks and partitions the module is installed, use module spider cpeCray/<version>.
