Version v0.1 |
An interactive GPU job needs to be submitted, the apptainer module loaded, and the following apptainer command to call Ansys Rocky:
| Code Block |
|---|
apptainer exec --nv --unsquash -H $HOME:/home -B /gpfs/sharedfs1/admin/hpc2.0/apps/ansys/2024R1:/ansys -B /gpfs/sharedfs1/directory/on/HPC/here:/shared/PI(group)/directoryHere AnsysRocky.sif /ansys/v241/rocky/Rocky |
Errors will show up, but say Y to the prompt Ansys Rocky gives about overwriting:
| Code Block |
|---|
mv: try to overwrite ‘/ansys/v241/rocky/Rocky.desktop’, overriding mode 0775 (rwxrwxr-x)? y |
If other errors show up, ignore the errors and rerun the above apptainer command a couple of more times until Ansys Rocky loads. The errors are Red Herring errors and can be ignored.
