Yo Ralph -- I'm assuming there's no plans for this kind of feature in v1.3 (Terry and I were talking "pie in the sky" kinds of ideas when we came up with this one). Should we shift it to "Future"?

As noted, it would be easy to implement, so I guess I don't care - could throw it into 1.3 or not.

Kinda up to you guys as to how badly you want it.

This feature is not absolutely necessary for 1.3 but I would like it in 1.3.1. I've discussed this with the RMs (Brad and George) and they are fine with this feature being added to 1.3.1.

Damien has a somewhat related issue - what he needs is basically a "spawn agent" similar to our "launch agent". If provided, this would be a cmd that executes each app when spawned.

In other words, you take the argv that is going to be fork/exec'd and prepend the spawn agent in it. Thus, the spawn agent is what actually executes the app.

I'm not sure if Damien is doing this work or not - perhaps he could confirm? Otherwise, I'll implement it over the next week or two (actually rather trivial to do).

Damien was having problems posting; he mailed his reply to me directly (see below). Damien: note that you can sign up for an account on our Trac and therefore be able to comment on tickets directly (our Trac does not currently accept emails as input).

I have received a query from the Openmpi tracker. The ticket https://svn.open-mpi.org/trac/ompi/ticket/1269 is an
enhancement to a "spawn agent".

This feature is not an issue for me.

My problem is to have an "orted local to mpirun",this is the only one
solution to , fix this problems:

• have no launch difference between mpirun node and other node
• have no ulimit difference between mpirun node and other node
• have no cpuset difference between mpirun node and other node
• have no bash difference between mpirun node and other node
• have no environment difference between mpirun node and other node

Please refer to Ralph for history and sorry for confusion.

I think it's pretty safe to say that this won't happen any time soon unless someone can free up some cycles to implement it.
