>>> You are absolutely correct, Terry, and the 1.4 release series does include the proper code. The point here, though, is that SGE binds the orted to a single core, even though other cores are also allocated. So the orted detects an external binding of one core, and binds all its children to that same core.
>> I do not think you are right here. Chris sent the following which looks like OGE (fka SGE) actually did bind the hnp to multiple cores. However that message I believe is not coming from the processes themselves and actually is only shown by the hnp. I wonder if Chris adds a "-bind-to-core" option we'll see more output from the a.out's before they exec unterm?

I would have expected more output.
