No we do not have a firewall turned on. I can run smaller 96 slave cases on ln10 and ln13 included on the slavelist. Could there be another reason for this to fail ? Sincerely, Waris Sindhi High Performance Computing, TechApps Pratt & Whitney, UTC (860)-565-8486 -Original Message-

[OMPI users] OpenMPI out of band TCP retry exceeded

Hi, I am getting a "oob-tcp: Communication retries exceeded" error message when I run a 238 MPI slave code /opt/openmpi/i386/bin/mpirun -mca btl_openib_verbose 1 --mca btl ^tcp --mca pls_ssh_agent ssh -mca oob_tcp_peer_retries 1000 --prefix /usr/lib/openmpi/1.2.8-gcc/bin -np 239 --app

Re: [OMPI users] srun and openmpi

Argh, our messed up environment with three generations on infiniband bit us, Setting openib_cpc_include to rdmacm causes ib to not be used on our old DDR ib on some of our hosts. Note that jobs will never run across our old DDR ib and our new QDR stuff where rdmacm does work. I am doing some
