Hardware
The CPU CLX partition offers 982 compute nodes equipped with Intel CPUs. One single compute node holds the following properties.a system based on Intel CPUs. For more details see also Slurm partition CPU CLX.
| node number | per node |
|---|---|
| 982 | 2x Intel Xeon "Cascade Lake" Platinum 9242 |
...
| 96 compute cores | |
384 GB RAM | |
Omni-Path OPA100 host fabric adapter |

Program build
Once you compiled a binary file (see the Compilation Guide) you need to execute your code. Serial and OpenMP is started directely. For MPI parallelized code you choose between two approaches, namely using srun or mpirun.
Serial and OpenMP parallel code
Please read the page Workflow compiler how to execute
- serial code,
- one OpenMP parallel code, or
- several OpenMP codes simultaneously.
MPI parallel code
Please read the page Workflow Intel MPI how to execute
- MPI parallel code or
- MPI, OpenMP hybrid parallel code.
...
Partition usage
To use CPU CLX partition, please
- create a binary like in Workflow CPU CLX,
- create a slurm job script like in Workflow CPU CLX,
- and submit the job like in Slurm partition CPU CLX.
