Ralph,
Thanks for the response !
If I substitute the output from `hostname` (Chucks-iMac.local) I get the same behavior, but using `hostname -s` (Chucks-iMac) all is well.
So, to summarize:
Fails:
mpirun -host localhost -np 1 java -version
mpirun -host `hostname` -np 1 java -version
Succeeds:
mpirun -host `hostname -s` -np 1 java -version
At least I have a fix for now !
Best regards,
Chuck Mosher

Hmmm...I would say there is a bug in 1.7 then! It isn't recognizing the word "localhost" as being your local host. I'll take a look at it.
Thanks!
