Description Kilian Cavalotti 2015-06-04 12:42:45 MDT 
Hi there,

I've re-read the man page for gres.conf and I'm confused. It says:

-- 8< ----------------------------------------------------------------------
File   Fully  qualified  pathname of the device files associated with a resource.  The file name parsing logic does not include any support for regular expressions. Each file must be explicitly named, one per line.  
-- 8< ----------------------------------------------------------------------

Yes, further down, the example seems contradictory:
-- 8< ----------------------------------------------------------------------
       ##################################################################
       # SLURM's Generic Resource (GRES) configuration file
       # Use a single gres.conf file for all compute nodes
       ##################################################################
       NodeName=tux[0-15]  Name=gpu File=/dev/nvidia[0-3]
       NodeName=tux[16-31] Name=gpu File=/dev/nvidia[0-7]
-- 8< ----------------------------------------------------------------------

So which one is it? One File= per line, or can they be regrouped as in the example?

Thanks,
Kilian

Regular expression support was added in version 14.11 as I recall. I'll update that documentation.
