Thanks, that helps know what command it expects back, but without
knowing the format of the rest of the response, the best we can do
is make the application coredump.  :)

I guessed wrong about tcpdump.  Whatever is going across the wire is
not straight PMI commands, maybe that only happens between a
launcher daemon on each compute node and the application itself.
Not sure how Intel structures all that.  Your nice tcpdump has
things that look meaningful, but it isn't PMI and doesn't appear to
translate easily.

Regarding the beta, I decided not to install their code.  Hopefully
they will respond nicely to your support question.
