No, as I replied to a previous poster, when you put "--exclusive" in the
sbatch command, that is over-ridden by the partition's Oversubscribe
setting.

I ended up just creating a "reservedq" and a "reservedsharedq".

It would be really great to have an equivalent to "--mem 0" (or
"--exclusive") that actually worked to request all the resources in a node.

thanks,
