Note this error as well -- make sure that this hostfile exists. If
you're running under Torque, you probably don't need a hostfile (I'm
not sure how well we've tested under Torque, but it won't be hard to
fix if there's a problem).

It's not that MTT itself requires SSL, it's that the OMPI test
results submission URL https because a password is sent.

Sorry. :-(
