Thanks Reuti. That sorted out the problem.
Now mpiblast is able to run, but only on single node. i.e. mpiformatdb
-> 4 fragments, mpiblast - 4 processes. Since each node is having 4
cores, the job will run on a single node and works fine. With 8
processes, the job fails with following error messag

Greetings,
I have observed strange behavior with an application running with
OpenMPI 1.2.8, OFED 1.2. The application runs in two "modes", fast
and slow. The exectution time is either within one second of 108 sec.
or within one second of 67 sec. My cluster has 1 Gig ethernet and
DDR Infiniband so

If the basic test run the installation is ok. So what happens when you
try to run your application ? What is command line ? What is the error
message ? do you run the application on the same set of machines with
the same command line as IMB ?

yes to both questions: the OMPI version is

For your runs with Open MPI over InfiniBand, try using openib,sm,self
for the BTL setting, so that shared memory communications are used
within a node. It would give us another datapoint to help diagnose
the problem. As for other things we would need to help diagnose the
problem, please follow th
