I see in your original note that you tried the 1.5.5 beta rc and got the same
results, so I assume this must be something in your system config that is

1.4.5 tarball.
I did some tests and it does not seem that i can make it work, i tried
these:
btl_sm_num_fifos 4
btl_sm_free_list_num 1000
btl_sm_free_list_max 100
mpool_sm_min_size 15
mpool_sm_max_size 75
I did try with both MaxSessions and MaxStartups set to 200, unfortunately
it did not help - I still got the same errors as before.

This may or may not be related, but I've had similar issues on RHEL
6.x and clones when using the SSH job launcher and running more than
10 processes per node. It sounds like you're only distributing 6
processes per node, so it doesn't sound like your problem, but you
might want to check your hostf
That fixed the issue but have brought a big question mark on why this
happened.
I'm pretty sure it's not a system memory issue, the node with least RAM has
8gb which i would think is more than enough.
Do you think that adjusting the btl_sm_eager_limit, mpool_sm_min_size, and
mpool_sm_max_size can
Afraid I have no idea how those packages were built, what release they
correspond to, etc. I would suggest sticking with the tarballs.
Your output indicates a problem with shared memory when you completely fill the
machine. Could be a couple of things, like running out of memory - but for now,
Hi,
Sorry that it took so long to answer, I didn't get any return mails and had
to check the digest for reply.
Anyway, when i compiled from scratch then i did use the tarballs from
open-mpi.org. GROMACS is not the problem (or at least i don't think so), i
just used it as a check to see if i could
I suspect you'll have to ask someone familiar with GROMACS about that specific
package. As for testing OMPI, can you run the codes in the examples directory -
e.g., "hello" and "ring"? I assume you are downloading and installing OMPI from
our tarballs?

Hello,
I have a very peculiar problem: I have a micro cluster with three nodes (18
cores total); the nodes are clones of each other and connected to a
frontend via Ethernet and Debian squeeze as the OS for all nodes. When I
run parallel jobs I can used up “-np 10” if I go further the job crashes,
