painful but OK. :)

currently, we use mpiexec as a job start-up mechanism. also because of
good integration with PBS Pro batch queueing system.

would it be a good time to switch to MVAPICH2? what is your and list
suggestion?

You are correct - I meant daily build from
http://www.openfabrics.org/downloads/OFED/ofed-1.3.2-daily/
anyway, OFED 1.3.1 also contains mvapich-1.0.1-2533.

thanks for all replies!
