Re: [OMPI users] Connection timed out with multiple nodes

The only relevant parts are from the application procs - orterun and the orted don't participate in this exchange and never see the BTLs anyway. It looks like there is just something blocking data transfer across eth2 for some reason. I'm afraid I have no idea why - can you run a standard (i.e.,

Re: [OMPI users] Connection timed out with multiple nodes

It's the failure on readv that's the source of the trouble. What happens if you only if_include eth2? Does it work then? Still hangs, details follow ... tx! o Using only eth2 with verbosity gives: [roberpj@bro127:~/samples/mpi_test] /opt/sharcnet/openmpi/1.6.5/intel-debug/bin/mpirun -np 2 -

Sorry for the typo: ** I was hoping to understand the impact of OpenMPI's implementation of these protocols using traditional TCP. This is the paper I was referring to: Woodall, et al., "High Performance RDMA Protocols in HPC". On 31 January 2014 00:43, Siddhartha Jana wrote: > Good evening >

Good evening Is there any documentation describing the difference in MPI-level implementation of the eager and rendezvous protocols in OpenIB BTL versus TCP BTL ? I am only aware of only the following paper. While this presents an excellent overview of how RDMA capabilities of modern interconnects
