Subject: [Mpi3-rma] Notes from RMA working group concall, Dec 9, 2008
Attendees:
Rajeev, Darius, Dave Goodell, Argonne
Bill Gropp, UIUC
Rich, Vinod, ORNL
Jesper, Hubert, NEC
Robert Blackmore, Su Huang, IBM
Howard Pritchard, Cray
Christian Bell, Myricom
Someone from PNNL (missed the name)
I may have missed others
* Discussion on issues with non-cache-coherent systems. Vinod is
preparing a presentation for the next Forum mtg. He needs
input from vendors who have (or will have) systems that are not
cache coherent or have special memory features.
* Vinod is updating the existing proposal and will send out a new
version before the Forum mtg.
* Vinod will check with Dan Bonachea if he can attend next mtg and his
thoughts on current proposal.
* Discussion on how does the target know of completion. Vinod will
clarify further in new version of proposal and FAQ.
* Long discussion on how to represent the target address. Currently it
is directly provided as a (void *), which won't work
everywhere. There was some consensus that it needs to be an object
of some kind. Care must be taken about scalability issues (don't
want a process to a hold a list of everyone's addresses).
* Ticket 35 (datatype and Op registration) and 37 (examples describing
synchronization semantics) were briefly discussed. Jesper will make
a presentation on 35 at the Forum mtg. Rajeev said having examples
like in #37 is a good thing; we need to make sure they are correct
(he thinks they are).
If I have missed anything, please add.
Rajeev
