Helios is a hybrid cluster. CPU nodes use x86_64 CPUs, while the GPU partition is based on GH200 superchips, which include an Nvidia Grace - ARM CPU and Nvidia Hopper GPU. HPE Slingshot is used as an interconnect. The login01 node uses an x86_64 CPU; please keep that in mind when compiling software, etc. Knowing the destination CPU architecture is important for selecting the proper modules and software. Node specification can be found below:
...
Applications and libraries are available through the modules system. Please note that the module structure was flattened, and module paths have changed compared to Prometheus Modules for ARM and x86 CPUs are not interchangeable, and selecting the right module for the destined architecture is key for getting software to work! Please load the proper modules on the node, inside of the job script! The list of available modules can be obtained by issuing the command:
