Hi,
I have trying to run the Intel IMB benchmarks to compare the performance of
Infiniband (IB) vs Ethernet. However, I am not seeing any difference in
performance even for communication intensive benchmarks, such as alltoallv.
Each one of my machines has one ethernet interface and an infiniband
i
I did a little more testing in case this helps... if I run ompi-server on
the same host as the one I call MPI_Publish_name() on, it does successfully
connect. But when I run it on a separate machine (which is on the same
network and accessible via TCP), I get the issue above where it hangs.
Thank
Well, your initial usage looks correct - you don’t launch ompi-server via
mpirun. However, it sounds like there is probably a bug somewhere if it hangs
as you describe.
Scratching my head, I can only recall less than a handful of people ever using
these MPI functions to cross-connect jobs, so i
I am trying to use ompi-server with Open MPI 1.10.6. I'm wondering if I
should run this with or without the mpirun command. If I run this:
ompi-server --no-daemonize -r +
It prints something such as 959315968.0;tcp://172.31.3.57:45743 to stdout
but I have thus far been unable to connect to it.
