Hello, With openmpi-1.3, new mca feature is introduced
namely --mca routed binomial. This ensures out of band communication to happen
in binomial fashion and reduces the net socket opening and hence solves file
open issues.-NeerajOn Thu, 18 Sep 2008 16:46:23 -0700 Open MPI Users wrote
I'm just running it using mpirun from the command line. Thanks for the reply.

Alex Wolfe Hello, I am trying to run the HPL benchmarking software on
a new 1024 core cluster that we have set up. Unfortunately I'm hitting the
"mca_oob_tcp_accept: accept() failed: Too many open files (24)" error known in
verson 1.2 of openmpi. No matter what I set the file-descriptor limit for my
account to, I am still limited to only 808 or so processes. Does anyone have
any suggestions? Are you running the Linpack via a batch system or
just using mpirun from the command line? If via a batch system, looks for
FAQs on how to set the resource limits for that batch system.
