problems on slurm cluster

HI,

This does not seem to be a SLURm related issue.
Did you try to run this without using slurm (if this is too long, just run the 0j multiplicity)
I have try on my machine (with 2.6.2) but did not reproduce such error locally.
Now this kind of remember me a similar bug report so if this is the case, you should reproduce that locally.

Cheers,

Olivier

The error is raised when the script tries to access the self["init"] of the banner file which apparently here doesn't exist. See the full traceback below.

The cluster uses slurm and I could easily request ~1000 cores if possible/reasonable. Would you recommend to restrict to a smaller number of nodes anyway to circumvent problems? Should one set $TMPDIR, if so should the individual jobs use the same $TMPDIR or is faster machine-local storage preferable? I also found an option cluster_temp_path, but I'm not quite sure if and how to set it.
