[Moabusers] Combining floating and generic licenses for the same software ?

[csamuel at vpac.org]

Hi folks,

I'm trying to help some people out with their Moab
configuration and there are some packages for which
they have both FlexLM and node locked licenses (for
historical reasons).   They wish jobs that request
this software to use the node locked licenses, if
available, in preference to the FlexLM licenses.

My thought was that I would need to assign a GRES to
the node which has the same name as the names that
returned via FlexLM, but I see odd things are happening.

If I submit a test job doing:

echo 'sleep 60; hostname' | qsub -l software=PA_MSC_NASTRAN -l nodes=1

then Moab reserves *two* nodes for it, one being the
system with the node locked GRES and the other being
the next available node.  But the hostname runs on the
*wrong* node, i.e. not the one with the license I requested.

This is what I have in their moab.cfg:

NODECFG[node004] GRES=NASTRAN:2,NA_Nonlinear:2,PA_MSC_NASTRAN:1

Here's what checkjob says:

job 188 (RM job '188.foo')

Any clues on what's going on here ?

Am I missing something ?
