This smacks of a firewall issue, I thought you'd said you weren't using one but
now I read back your emails I can't see anywhere where you say that. Are you
running a flrewall or any iptables rules on any of the nodes? It looks to me
like you may have some setup from on the worker nodes.

If that does not work, then we know the problem is in the runtime. If
it does works, then
there is something with the way the MPI library is setting up its

Interesting.

Yes. I am able to log in remotely to all nodes from the master, and to each node from each node

Hello,
the InfiniBand architecture has a LMC feature to assign mutiple virtual
LIDs to one port and so provides multiple paths between two ports. Is
there a methode in openmpi to enable message-striping over these paths
to increase bandwidth or avoid congestions?

Hello,
In January, I reported a problem with Open MPI 1.4.1 and PathScale 3.2
about a simple Hello World that hung on initialization
( http://www.open-mpi.org/community/lists/users/2010/01/11863.php ).
Open MPI 1.4.2 does not show this problem.
However, now we are having trouble with the 1.4.2, P

Hi,
Sorry, but i get lost in what i wanna do, i have build a small home cluster
with Pelican_HPC, that user openMPI, and i was trying to find a way to get a
multithreaded program work in a multiprocess way without taking the time to
learn MPI. And my vision was a sort of wrapper that take C posix

I don't know if i correctly understand what you need, but have you
already tried MPI_Comm_spawn?
