- 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. For build examples, please visit our manual on
- GPU-aware MPI: For efficient use of MPI-distributed GPU codes, an GPU/CUDA-aware MPI installation of Open MPI is available in the
openmpi/gcc.11/4.1.4
environment module. Open MPI respects the resource requests made to Slurm. Thus, no special arguments are required tompiexec/run
. Nevertheless, please consider and check the correct binding for your application to CPU cores and GPUs. Use--report-bindings
of mpiexec/run to check it.
