Regarding numactl, we are using it and shows good results:
numactl --hardware
available: 3 nodes (0-2)
node 0 size: 57280 MB
node 0 free: 32579 MB
node 1 size: 57255 MB
node 1 free: 55920 MB
node 2 size: 16371 MB
node 2 free: 16140 MB
(on a 128GB system, SLES10SP1)
sounds like an altix. yes, it works fine on our 64 node altix as well.
what I'm wondering is how widespread it is to find commodity PCs that
have inconsistent numactl output.
incidentally, do you use node memory availability
to balance job/thread placement?
