Re: [ptp-user] ptp/slurm: How to redefine location of .eclipsesettings -- $HOME is not mounted on compute nodes.
|
I’m a bit puzzled as to why it matters if the home directories are mounted on the compute nodes or not. Normally the batch script would be placed in $HOME/.eclipsettings/…managed_file_for_script, then the sbatch command executed with this path as an argument. This would happen on the login node, so should be independent of the compute nodes. Can you try creating a simple script, put it in $HOME/.eclipsesettings/foo, then run “sbatch $HOME/.eclipsesettings/foo” from the command line on the login node?
