Subject: [OMPI devel] RTE issues: scalability & complexity

Yo all

As (I hope) many of you know, we are in a final phase of revamping ORTE to
simplify the code, enhance scalability, and improve reliability. In working
on this effort, we recently uncovered four issues that merit broader
discussion (apologies in advance for verbosity). Although these somewhat
relate, I realize that people may care about some and not others. Hence, to
provide the chance to only comment on those you -do- care about, and to at
least somewhat constrain the length of the emails, I will be sending out a
series of four emails in this area.

The issues will include:

I. Support for non-MPI jobs

II. Interaction between the ROUTED and GRPCOMM frameworks

III. Collective communications across daemons

IV. RTE/MPI relative modex responsibilities

Please feel free to contact me and/or comment on any of these issues. As a
reminder, if you do comment back to the Devel mailing list, please use
"reply all" so I will also receive a copy of the message.

Thanks
Ralph
