are you saying both IP are the ones of the VM on which mpirun is running ? orted is only launched on all the machines *except* the one running mpirun.
can you double/triple check the IPs are ok and unique ? for example, mpirun --host <internal IP> /sbin/ifconfig -a can you also make sure Open MPI is installed on all your VMs in the same directory ? also make sure Open MPI has all the dependencies on all the VMs ssh xxx ldd `which orted` should show no missing dependency generally speaking, I recommend you configure Open MPI with --enable-mpirun-prefix-by-default you can also try to replace mpirun with `which mpirun` or mpirun --prefix <path to Open MPI> Cheers, Gilles On Thursday, June 2, 2016, Ping Wang <ping.w...@asc-s.de> wrote: > Hi, > > I've installed Open MPI v1.10.2.
