We have used the lspci -vvxxx and we have obtained:

This is the output for the Intel GigE NIC, you should look at the
to reset each NIC in its PCI slot, or use a different slot
if available.
Hope it helps.

So is this a problem with the physical switch (we need a better switch)
or with the configuration of the switch (we need to configure the switch
or configure the os to work with the switch)?
You may want to look if you are dropping packets somewhere. You can look
at
to terminate the job when a send timeout has occurred.
We will implement this mechanism and push it on the trunk shortly.
Thanks

I have built the release candidate for ga-4.1 with OpenMPI 1.2.3 and
portland compilers 7.0.2 for Myrinet mx.
Which version of ARMCI and MX ?
ARMCI configured for 3 cluster nodes. Network protocol is 'MPI-SPAWN'.
0:Segmentation Violation error, status=: 11

Just to check, you are not using the MTL for MX, right ? Only the BTL
interface allow to choose between several devices at run time.

Is it possible to get the same blocking behavior with openmpi? I'm
having a difficult time getting this to work properly. The application

Per its design, OpenMPI cannot block. sched_yield is all it can do to

I understand your position, and I used to agree

don't have several processors.
importantly, how to I reconfigure OPENMPI to match the LAM performance.
Try disabling the shared memory device in OpenMPI. Unfortunately, I have
no clue how to do it.

Politically speaking, 1) will never happen. MorphMPI could do 2), but
it's not a silver bullet.

What Jeff thought is a nightmare, I believe, is to have to decide a

them in a table. You have as much work as your internals are far from
the common interface and, hopefully, it will be a midpoint for everybody.
