Ah, Ok. So you have
PriorityFlags=MAX_TRES
too.

Yup, tks.

Now I have to understand why my definition of

NodeName=str957-mtx-00 Sockets=2 CoresPerSocket=14
ThreadsPerCore=2 Feature=ib,nonblade,intel MemSpecLimit=1024

gives

# scontrol show node str957-mtx-00
scontrol: error: NodeNames=str957-mtx-00 MemSpecLimit=1024 is invalid,
reset to 0

I tried lowering it down to 2, same result...

Node is turned off for maintenance, but RealMemory is OK...
