Subject: Re: [OMPI users] OPENMPI_ORTE_LOG_ERROR
From: Ada Mancuso (mancuso.ada_at_[hidden])

Hi,
I've installed the latest snapshot taken from svn developer's trunk but I
had the same problems. This is my configuration:

   - Ubuntu 2.6.38-8 kernel
   - Openssh_5.8p1 openssl 0.9.8o
   - Libtool version 2.4
   - Open mpi 1.7 rc5 and latest snapshots.

Do you think my problem could be related with the operating system used or
with any parameter or configuration? I've also checked the ssh log file but
I didn't find any problem.
Thanks in advance
Ada

If so where can I find it?

fixed. We are getting ready to release an updated rc, so you might want to
try it (or use the latest nightly 1.7 snapshot).

works well on each machine and I also tried to run my program with
different couple of machines in order to be sure that no machine could be
the problem.
