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 the one that comes with
OFED (1.1.2-1) and the basic tests run fine. For instance, IMB-MPI1
(which is more than basic, as far as I can see) reports for the last
test:
#---------------------------------------------------
# Benchmarking Barrier
# #processes = 6
#---------------------------------------------------
#repetitions t_min[usec] t_max[usec] t_avg[usec]
1000 22.93 22.95 22.94
for the openib,self btl (6 processes, all processes on different nodes)
and
#---------------------------------------------------
# Benchmarking Barrier
# #processes = 6
#---------------------------------------------------
#repetitions t_min[usec] t_max[usec] t_avg[usec]
1000 191.30 191.42 191.34
for the tcp,self btl (same test)
No anomalies for other tests (ping-pong, all-to-all etc.)
Thanks,
