_______________________________________________2008/9/18 Alex Wolfe <email@example.com>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.
