Description CSC sysadmins 2014-10-22 21:09:09 MDT 
Hi,

I'd like to be able to define more than one partition on the S*_PARTITION env variable but I've not found proper syntax for that, e.g. like following example:

SINFO_PARTITION="gpu,mic"

Another problem is that users are not able to override this env variable, sinfo -a will not show any other partitions than which is defined by SINFO_PARTITION=
Comment 1 Brian Christiansen 2014-11-04 04:37:17 MST 
This is fixed in the following commit:
https://github.com/SchedMD/slurm/commit/46c8fb7a86d2ebfc95faa06e00ca23d9eb16be78

The following is example output:

compy$ SINFO_PARTITION=debug1 sinfo

Comment 2 Brian Christiansen 2014-11-04 06:05:05 MST 
Updated commit to make -a and -p overwrite environment variables but not override each other on the command line.
