Subject: [OMPI users] Linpack Benchmark and File Descriptor Limits
From: Alex Wolfe (awolfe_at_[hidden])

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?
