Intel MPI 5.0.2.044 and Windows firewall on localhost

652 Views

Hi everybody,

We run mpiexec on Windows 7 on multiple network installations of our product in the following manner:

mpiexec.hydra.exe -np x -localroot -delegate -localonly -localhost 127.0.0.1 one_path_to_EXECUTABLE

The problem is with the windows firewall (which is executable path triggering) and alerts, because mpiexec.hydra.exe and pmi_proxy.exe do a listen on 0.0.0.0:port.

Is there an option / environment variable available to tell mpiexec.hydra only listen on 127.0.0.1 instead of all available interfaces if we run it only local on one workstation.

Thanks in advance

Frank
