I am working with a ScaleMP linux system which consists of 10 dual
socket blades which creates 10 nodes 0-19. due to the cpu speed on 4 of
the blades they show up a nodes with memory but no cpus ,
My mom layout
cpus=0-11 mem=0,1 memsize=441738948
cpus=12-23 mem=2,3 memsize=441738948
cpus=23-35 mem=4,5 memsize=441738948
cpus=36-47 mem=6,7 memsize=441738948
cpus=48-59 mem=8,9 memsize=441738948
cpus=60-71 mem=10,11 memsize=441738948
for the first 6 baldes , they show up as <hostname>-0...5 in pbsnodes
and in moab's mdiag -n I would like to be able to submit to a job
locked to a "blade" which can use memory from other/(the additional mems
12-19) in the preferred allocation strategy, getting memory from the
local node first , then from others. How do I tell moab/torque that the
available memory is the "SUM" of the memory on all the nodes + the extra
non-cpu nodes not the available memory each individual node? And how do
I configure in nodes 12-19 I tried adding them to the mem=-0.1,12,13...
lines but I don't want them to be preferred per-say .
