Ah, this clears things up a bit. I still feel that using shared
fileseeks is a dangerous practice however, so I will steer clear of them
for now. I did this small experiment on a Macbook Pro with Snow Leopard
10.6.7, so the file system is HFS+. I just did the file size example
since it was simple,
You should probably also use open MPI's native torque support instead of a
hostile.

Libnuma will be used automatically if you use a paffonity setting.
But note that it only applies to internal memory in OMPI - I don't remember the
version offhand, but late in the 1.5 series we set the general affinity policy
for all memory (possibly the unreleased 1.5.4?).

Hi Jeff,
Thanks for following up. I have a question to clear things.
1. If I do not specify any affinity in mpirun, what memory allocation policy
is used by default?
a. When it is not compiled with libnuma
b. when compiled with libnuma
BTW What do you mean by "internal memory" in OMPI?
