No hybrid call on Sep. 9th
by Pavan Balaji 26 Aug '13

Since we have the Forum meeting two weeks from now, let's cancel the hybrid call that week. The hybrid plenary is from 1.30pm on Friday (Sep. 13th). That's 7am eastern, 6am central, insane hour pacific. There'll be a webex for folks to call in. -- Pavan -- Pavan Balaji http://www.mcs.anl.gov/~balaji

Please try it out early on your laptop, since it downloads some Java thingy the first time you launch it. You probably don't want to be doing that during the call. -- Pavan On 08/26/2013 12:29 PM, Jeff Squyres (jsquyres) wrote: > We'll be using Webex for future Hybrid WG meetings so that we can share screens, view slides together, etc. > > Here's the info (I'll put this on the wiki, too): just click the link below to join the meeting.

Re: [mpiwg-hybridpm] Feedback on init/finalize slides
by Jim Dinan 21 Aug '13

21 Aug '13

- Slide 20: Jim wants "low-quality implementations" to be called "simple implementations" to save face :-). JMS 20 Aug 2013: Is this a real comment or a joke? Yes, I actually asked for that change, for serious. :) For some networks, never actually finalizing MPI/network when the init/finalize count reaches zero is the only way to implement this. So, I wouldn't really consider this to be a quality of implementation issue, because implementors have no other other choice. - Slide 26: There is some conflict between the notion of INIT/FINALIZE being collective vs. they being synchronizing. We wanted to call them collective, so it is illegal for some processes in an application to do 3 INITs/FINALIZEs and some processes to do 2. But we also didn't want all calls to be synchronizing (specifically for the case of connect/accept). We need to figure out how to phrase this. Maybe we completely get rid of the notion of these calls being collective, and just say that the initializing and finalizing calls be collective. Everything else is really local-only. So this would be a valid program: - P0 does INIT/INIT/FINALIZE/FINALIZE - P1 does INIT/FINALIZE JMS 21 Aug 2013: Good points. I therefore made the definition on slides 8 and 13 stronger: MPI_INIT that does not start an epoch / MPI_FINALIZE that does not close an epoch is a local-only operation. On slide 13, "INIT and FINALIZE are still collective ... but only when they open / close an epoch" is not correct. Init and finalize are *always* collective, but they may not be synchronizing. Are we over-specifying here? Can we just call these collective and leave synchronization to an implementation choice? ~Jim.
