Hi, On Open MPI 1.2, I used following command to get the default host file: ompi_info -a --parseable | grep rds_hostfile_path
Now, on Open MPI 1.3, the parameter does not seem to exist anymore. I checked that there is another parameter (mca:orte:base:param:orte_default_hostfile), but its value is always empty.
Which file whould I used for a system-wide default host file? Is there another way to query the path for this default host file? Or is a command to query which hosts are going to be used by mpi by default?
Best regards, Daniel Felix Ferber
