Subject: [OMPI users] FW: Performance issue of mpirun/mpi_init

I just will confirm that the issue has been fixed. Specifically, with the latest OpenMPI v1.8.1a1r31402 we need now 2.5 hrs to complete verification and that timing is even slightly better compared to v1.6.5 (3hrs).

Thank you very much for your assistance!

With best regards,

>I shaved about 30% off the time - the patch is waiting for 1.8.1, but you can try it now (see the ticket for the changeset):
