Re: [OMPI users] mca_oob_tcp_peer_complete_connect: connection failed

Sorry I wasn't clear enough on my previous post. The error messages that you get are comming from the OOB which is the framework we're using to setup the MPI run. The options that you use (btl_tcp_if_include) are only used for MPI communications. Please add "--mca oob_tcp_include eth0" to force

Re: [OMPI users] mca_oob_tcp_peer_complete_connect: connection failed

Thanks for the tip. I see that both number 1 and 2 are true. Openmpi is insisting on using my eth0 (I know this by watching the firewall log on the node it is trying to go to) This is despite the fact that I have the first dns entry go to eth1, normally that is all pbs would need to do the right

Re: [OMPI users] mca_oob_tcp_peer_complete_connect: connection failed

I see only 2 possibilities: 1. your trying to run Open MPI on nodes having multiple IP addresses. 2. your nodes are behind firewalls and Open MPI is unable to pass through. Please check the FAQ on http://www.open-mpi.org/faq/ to find out the full answer to your question. Thanks, george.

Hello, I'm just compiled open-mpi and tried to run my code which just measures bandwidth from one node to another. (Code compile fine and runs under other mpi implementations) When I did I got this. uahrcw@c275-6:~/mpi-benchmarks> cat openmpitcp.o15380 c317-6 c317-5 [c317-5:24979] [0,0,2]

Hi Jean, Take a look here: http://www.open-mpi.org/faq/?category=infiniband#ib- leave-pinned This should improve performance for micro-benchmarks and some applications. Please let mw know if this doesn't solve the issue. Thanks, Galen On Mar 16, 2006, at 10:34 AM, Jean Latour wrote: Hel

Re: [OMPI users] problems with OpenMPI-1.0.1 on SunOS 5.9; problems on heterogeneous cluster

Hi Brian, I have installed OpenMPI-1.1a1r9260 on my SunOS machines. It has solved the problems. However there is one more issue that I found in my testing and that I failed to report. This concerns Linux machines too. My host file is hosts.txt - csultra06 csultra02 csultra05 csultra08
