Yes, we should change this (IMHO) :).
Me too.
If so, who wants to be involved in the re-design? I'm pretty sure it
would require some modification of the paffinity framework, plus some
minor mods to the odls framework and (since you cannot bind a process
other than yourself) addition of a new small "proxy" script that
would bind-then-exec each process started by the orted (Eugene posted
a candidate on the user list, though we will have to deal with some
system-specific issues in it).
I can't contribute a whole lot of time, but I'd be happy to lurk,
offer advice, and write some small bits of code. But I definitely
can't lead.
Fist offering of opinion from me. I think we can avoid the "proxy"
script by doing the binding after the fork but before the exec. This
will definitely require minor changes to the odls and probably a bunch
of changes to the paffinity framework. This will make things slightly
less fragile than a script would, and yet get us what we want.
I'll have to talk with Len to see if Sun has any time to allocate to this.
