We recently tried to have jobs in a particular class (PBS queue) run on
nodes that can be drawn from two different maui PARTITIONS.
It looked, from the documentation, like the option "FLAG=SPAN", either in
a QOSCFG line that is later applied to a CLASSCFG; or directly applied to
a CLASSCFG. But it didn't seem to do anything. Jobs would run in one
queue or the other, but wouldn't span them. checkjob would produce:
job cannot run in partition PART1 (insufficient idle procs available: 4 < 16)
cannot select job 77352 for partition PART2 (Class)
Is there any more documentation on the use of "FLAG=SPAN" that someone can
point me to? I very much suspect that I'm misunderstanding it or have
some other, conflicting configuration somewhere in maui or PBS.
More information about the mauiusers
