Hi all,
it is more hardware or system configuration question but
I hope people in this list have an experience.
I have just added new ConnectX IB card to cluster with InfiniHost cards.
And no mpi programs work. Even ofed's tests do not work.
For example ib_send_*, ib_write_* just segfault on th
Thank a lot Ralph,
I just recompiled OpenMPi and it is seems to work as I expect.
So, I now start to make additional tests.
Thanx again.

Hi folks,
I am misunderstanding with OpenMPI. I cannot run jobs compiled by OpenMPI on
several nodes.
It is running only on the one node. But also in this case jobs are not finished
sometimes. Its make
output and hang.
But other MPI implementations (mpich, mpich2, mvapich1, mvapich2) work

you are right it should.
But I want to exclude any traffic from OpenMPI communications, like NFS,
traffic from other jobs and so on.
And use only special ethernet interface for this purpos
Hi folks,
I want to use for openmpi communication the additional ethernet interfaces on
node and head node.
its is eth1 on nodes and eth4 on head node.
So how can I configure openmpi?
If I add in config file
btl_base_include=tcp,sm,self.
btl_tcp_if_include=eth1
will it work or not?
And how i
