[Mauiusers] node prioritization based on node features

Hi,

I have some compute nodes that have 12GB of RAM, which will be
referred to as STDMEM nodes (actually a torque nodes file feature
string) and some compute nodes that have 48GB of RAM, which will be
referred to as BIGMEM nodes (also a nodes file feature string). If I
want to prioritize that users' jobs be run on STDMEM nodes before
BIGMEM nodes (as long as they don't request >= mem=12000mb) should I
just use the MINRESOURCE NODEALLOCATIONPOLICY or should I use PRIORITY
NODEALLOCATIONPOLICY and set PRIORITY=200 in the NODECFG lines for the
STDMEM nodes and PRIORITY=100 in the NODECFG lines for the BIGMEM
nodes?

Thanks,
Sabuj Pattanayek
