Hello,
I'm having issues running ANSYS CFX calculations across multiple nodes.
Single-node simulations run fine, but multi-node configurations crash because ssh connections are being denied:
" +--------------------------------------------------------------------+
| An error has occurred in cfx5solve: |
| |
| Remote connection to ncm0791.hpc.itc.rwthaachen.de |
| (ncm0791.hpc.itc.rwth-aachen.de) could not be started, or exited |
| with return code 255. It gave the following output: |
| |
| Permission denied (publickey,gssapi-keyex,gssapi-with-mic,pass- |

| Check that you have typed the hostname correctly, and that you |

| |
| ssh ncm0791.hpc.itc.rwth-aachen.de uname |

Am I missing something in my submission script, or is this a cluster config issue?
Regards,
Thomas Gier
