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 restrict our presentation to examples. For that, please visit our manual on

• OpenMP for GPU A100.

Job monitoring

A running job can be monitored interactively, directly on each of the compute nodes. Once you know the names of the job nodes you can login and monitor the host CPU as well as the GPUs.
