HI,
I read some howtos at OpenMPI official site but i still have some problems here.
I build a Kerrighed Clusters with 4 nodes so they look like a big SMP
machine. every node has 1 processor with dingle core.
1) Dose MPI programs could be running on such kinds of machine? If
yes, could anyone sh

Hi Josh,
I can't access the link you gave. Its a secure link and I think needs
authentication.
Thanks

Hi, all,

has different number of neighboring processes. Suppose each process has n

Hi David
You are quite correct. IIRC, we didn't bother checking the local_err
because we found it to be unreliable - all Torque checks is that the
program exec's. It doesn't report back an error if it segfaults
instantly, for example, or aborts because it fails to find a required
library.
Just a couple of data points:
1. so we don't confuse folks, there is no legal thing about a space in
OpenMPI. Heck, most of us developers drop the space in our

The Mellanox has a newer fw for those HCAshttp://

I am not sure if it will help, but newer fw usually have some bug fixes.

Maybe this should go to the devel list but I'll start here.
In tracking the way the PBS tm API propagates error information
back to clients, I noticed that Open MPI is making an incorrect
assumption. (I'm looking 1.3.2.) The relevant code in
orte/mca/plm/tm/plm_tm_module.c is:
