Thanks for the info. Using 6.7.0 solved my problem, but I'll remember the local option if I'm ever forced to use an older version.

Best,

Jeff

Motivation: I am trying to enable Charm++ and AMPI in Travis CI for the
Parallel Research Kernels.

Problem: See below. I cannot launch Charm++ programs with charmrun because
ssh fails. Because this is Travis CI, it is not interactive, and whatever
needs to be done to fix the otherwise trivial issue with localhost
authentication needs to be something that can be completely automated.

Is there a way to tell charmrun to ignore the localhost issue? If not, can
one be added? I'd like to avoid making a change downstream because then
I'll have to verify and possibly redo it for future releases of Charm++ if
charmrun changes. And I don't want to be mucking around with SSH settings
in Travis CI instances.
