How SU2 uses multi-node parallel computation

Hello all!

Can anyone knows how to write the command when SU2 adopts multi-node parallel computing ?

Thank you very much!

Hi,

I am not sure whether I understand the question correctly. I now assume you do not use hybrid-parallelization (i.e. MPI+openMP).

The distribution on different nodes on a cluster (I now assume you are on a cluster) is done by a scheduler (lsf, slurm, ...). So you only have to specify the number of processes like mpirun -n 100 SU2_CFD config.cfg and the rest happens to the will of the scheduler.

Let me know wheather that answers your question

Best, Tobi
