To rhc,
Thanks for those suggestions. Here are the results:
(1) Add "--oversubscribe" to mpirun cmd (I also added
"--output-filename junk" -- see other output below).
Terminal output had this fairly usual error message (shortened):
---
Child
Couple of things you can try:
* add --oversubscribe to your mpirun cmd line so it doesn’t care how many slots
there are
* modify your MPI_INFO to be “host”, “node0:22” so it thinks there are more
slots available
It’s possible that the “host” info processing has a bug in it, but this will
tell
