Subject: [OMPI users] How to override default hostfile to specify host
From: Saurabh T (saurabh_at_[hidden])

Hi,

If I use "orterun -H <machine>" and <machine> does not belong in the default hostfile ("etc/openmpi-default-hostfile"), openmpi gives an error. Is there an easy way to get the aforementioned command to work without specifying a different hostfile with <machine> in it? Thank you.
