| -mpp -dis -machines bcn1001:96:bcn1003:96 | distributed memory parallel on multiple 96-core-nodes |
To explore other settings it is recommend to start the general Ansys launcher GUI (command "launcher") and setup you specific setting. If you run the (test) job from this GUI it will print out the resulting terminal command. Then you can copy the resulting command/flags to your specific Slurm job script file.
