Jeff,
thanks a lot for taking the time to look at my file and sorry for not
having noticed that part of the README, it went straight past me.
Anyway with your suggestion it works perfectly.
Thanks again, Daniel.

It looks like you compiled Open MPI against the QLogic PSM libraries
-- I see the PSM MTL plugin available. Here's some text from the OMPI
v1.3 README that clarifies the situation:
- There are two MPI network models available: "ob1" and "cm". "ob1"

Sub 3us latency rules out IPoIB for sure. The test below ran on native IB or
some other very low latency path.

Jeff,
I put most of the info at:
http://www.bartol.udel.edu/~ddm/ompi_debug.tgz
The tar file contains the config.log, the ifconfig for the two nodes and
the output of ompi_info --all.
As I said I was running with:
mpirun --mca btl tcp,self --prefix /share/apps/openmpi-1.3/gcc_ifort/
Can you send the full output described here (including all network
setup stuff):

It is quite likely that you have IPoIB on your system. In that case,
the TCP BTL will pickup that interface and use it.
If you have a specific interface you want to use, try -mca
btl_tcp_if_include eth0 (or whatever that interface is). This tell the
TCP BTL to only use the specified interfa
Hi All,
I'm doing some tests on a small cluster with gigabit and infiniband
interconnects with openmpi and I'm running into the same problem as
described in the following thread:
http://www.open-mpi.org/community/lists/users/2007/04/3082.php
Basically even if I run my test with:
mpirun --mca btl
12 matches
