Can you send the full verbose output with "--mca btl_base_verbose 100"? > On Jul 4, 2018, at 4:36 PM, carlos aguni wrote: > > Hi Gilles. > > Thank you for your reply! :) > I'm now using a compiled version of OpenMPI 3.0.2 and all seems to work fine > now. > Running `mpirun -n 3 -host

Re: [OMPI users] Disable network interface selection

Carlos, Open MPI 3.0.2 has been released, and it contains several bug fixes, so I do encourage you to upgrade and try again. if it still does not work, can you please run mpirun --mca oob_base_verbose 10 ... and then compress and post the output ? out of curiosity, would mpirun --mca

Hi! Thank you all for your reply Jeff, Gilles and rhc. Thank you Jeff and rhc for clarifying to me some of the openmpi's internals. >> FWIW: we never send interface names to other hosts - just dot addresses > Should have clarified - when you specify an interface name for the MCA param, then it

Re: [OMPI users] Disable network interface selection

Carlos, By any chance, could mpirun—mca oob_tcp_if_exclude 192.168.100.0/24 ... work for you ? Which Open MPI version are you running ? IIRC, subnets are internally translated to interfaces, so that might be an issue if the translation if made on the first host, and then the interface name

[OMPI users] Disable network interface selection

Hi all, I'm trying to run a code on 2 machines that has at least 2 network interfaces in it. So I have them as described below: compute01 compute02 ens3 192.168.100.104/24 10.0.0.227/24 ens8 10.0.0.228/24 172.21.1.128/24 ens9 172.21.1.155/24 --- Issue is. When I execute `mpirun -n 2
