Jeff, We need to decide on INITIALIZED/FINALIZED vs. IS_WITHIN_EPOCH in the working group and take the final decision to the Forum, instead of wasting the Forum's time on that. -- Pavan On 07/29/2013 11:43 AM, Jeff Squyres (jsquyres) wrote:

I made a few more edits while Brian/Jim/Keith/Pavan are still arguing. :-)

Here's a new copy...

Here's a new copy of the slides; if we have time today, we can discuss.

I took all feedback, except I disagreed with Steve's #5 and #8.

Jeff,

Some comments --

1. Slide 2: The main goals need to be rephrased. The goals are to overcome limitations while using MPI in stacked and threaded libraries. For stacked libraries, the single INIT/FINALIZE limitation requires each library to have global knowledge on who else is using MPI. For threaded libraries, there are race conditions.

2. Slide 5: Sorry, I missed this earlier. I'm not in favor of changing the current definitions of IS_INITIALIZED and IS_FINALIZED. Better to deprecate them and add MPI_IS_WITHIN_EPOCH.

3. Slide 10: I don't think we agreed that the requested level will be ignored by subsequent calls. That's a quality of implementation issue.

4. Slide 15: We can say that our current stand is to remove that restriction that the "main thread" needs to finalize.

Btw, I've requested for plenary time.

Here's a better cut of slides that are more Forum-friendly.

Comments welcome.

(Pavan: I'm correct in thinking that you're getting plenary time from Martin for this, right?)
