Hi,
I am trying to get OpenMPI running on my home network. This has two
machines, t61 and quad, both running SuSE 11. I'm using the "hello_c"
program from the examples as a test. It will run fine on each machine,
using whatever number or processes I specify. However, when I try to
run on multi

On the node you are running ompi_info is there a Truescale card present? i.e.
is /dev/ipath created and the ib_qib driver loaded? If not can you rerun
ompi_info on a node that does have it loaded (compute nodes?) and see if it
shows up. This is expected in the above scenario as the PSM m
I also forgot to add that one of the bonus requirements for my project is to
be able to use it with whatever number of slave nodes, which i think makes
the whole deal a lot more complicated.

Hey guys,
I need to write an implementation of a 4D array with a variable 4th
dimension based on where in 3D you are. So it's basically like a normal
rectangular prism, except for each unit it might have a variable number of
values. The program is also supposed to communicate by sending ghost node
Should we replace OMPI's use of sched_yield() with usleep()?
David -- could you try replacing the call to sched_yield() in
opal/runtime/opal_progress.c (somewhere around line 220) to usleep(1) and see
if that gives the behavior that you want (without twonking a /proc value)? You
might also hav
