I certainly don't (nor anyone in PTP as far as I know) have the

that 1.2 will be the end of the line for PTP supported versions. As I
mentioned to Ralph, I don't follow your developer discussions closely
enough to understand the details of every change that is proposed.
I can understand that.
But please also appreciate our point of view: we put out public
notices saying that interface changes were going to occur and
specifically, deliberately asked if anyone cared. IBM did not say
"stop!!". If no one says anything, how are we to know that what we're
doing is going to adversely affect anyone?
Looking back through the mailing list, I can only see two references
that seem relevant to this. One was titled "Major reduction in ORTE"
and does allude to the event model changes. The other "OMPI/ORTE and
tools" talks about "alternative methods of interaction". Neither
mentions changes to the spawning and I/O forwarding functionality
(that I can see), or that this would be the exclusive mechanism for
interaction. In the future (assuming there are more changes), it would
be helpful if there was at least some information about what specific
API's are being removed.
BTW, IBM is simply a stakeholder in PTP. It's not up to IBM to make
this decision.
Cheers,
Greg
