Software and environment modules

• Login and compute nodes of the A100 GPU partition are running under Rocky Linux (currently version 8.6).
• Software for the A100 GPU partition provided by NHR@ZIB can be found using the module command, see Quickstart.
• Please note the presence of the sw.a100 environment module. It controls the software selection for the GPU A100 partition.

Program build and execution

• Each node of the GPU A100 system is a combination of a host CPU and their four attached device GPUs. There is a wide range of software to support this hardware.
• We recommend to use the GPU A100 login nodes for program build. If a program build needs for the presence of CUDA drivers, compilation is possible on a compute node within a slurm job session, too.
• We restrict our presentation to examples. For that, please visit our manual on
  • OpenMP for GPU A100,
  • CUDA.
