Hi all,
I am having an issue with mpiexec, I have a bundled install with Fire Dynamics Simulator (FDS) and I am attempting to run a simple hello world script that is bundled with FDS called test_mpi link: https://github.com/firemodels/fds/blob/master/Utilities/test_mpi/test_mp...
The issue I have is if I run:
'mpiexec -hosts 2 non-local-machine 1 local-machine 1 test_mpi'
I get the hello work with the rank, however, if I swap such that the local-machine is first, I only get the localhost machine reported with the non-local-machine never replying.
Should this be an expected result or is there an issue somewhere?
