I have - again - successfully built and installed
mx and openmpi and I can run 64 and 128 cpus jobs on a 256 CPU cluster
version of openmpi is 1.2b1
compiler used: studio11
The code is a benchmark b_eff which runs usually fine - I have used extensively
it for benchmarking
When I try 192 CPUs I get
m2001:16147] mca_oob_tcp_accept: accept() failed with errno 24.
