Can we put streams first? My Tuesday morning is hell due to remote events. If there's a time zone issue here for somebody, I can live with 9 AM, although I'll note that 9-10 AM conflicts with the OFI WG that some of us usually attend.

Hi Dan, I agree that it would be helpful to review the wildcards info key to gather more inputs and make sure that folks in the P2P WG are comfortable with the proposal. The process could have been better, most of that is my fault, but let's not miss this opportunity to be the first MPI 4.0 ticket. :) If possible, a little WG time to review other info keys and prioritize would be helpful so that we can pick up and move forward the other great ideas that are captured on the ticket. We definitely do have other info keys that belong in this working group. Safe travels and see you next week! ~Jim.

Schedule for Dec 2014 face-to-face meeting in San Jose
by Daniel Holmes 04 Dec '14

04 Dec '14

Hi all, I propose the following as the initial schedule for the P2P WG time at the face-to-face WG meeting in San Jose: 09:00 Receive w/reduce (30 minutes) 09:30 Allocate receive (30 minutes) 10:00 -----Break------ (30 minutes) 10:30 Wildcards ticket (15 minutes) 10:45 Streams/channels (75 minutes) 12:00 -----Lunch------ (60 minutes) Jeff Hammond will be presenting some new information about "receive with reduce" and "allocate receive". The "wildcards ticket" is intended to be a short time to make a decision on whether or not the P2P WG should pick up and drive the spin-off INFO keys ticket (#461) that proposes a couple of "no wildcards" keys and whether or not to offer to take on other proposed keys (as long as they are P2P-related) as lower priority items (e.g. "only_any_source" and "only_any_tag"). Finally, we still have a lot of material regarding streams/channels to discuss. (Note-to-self: Takeshi Nanri, Kyushu Univ., Japan on channels in ML and Xiaoyi Lu, Ohio State Univ., USA on DataMPI.) I realise that many P2P WG members are also Hybrid WG members and the parallel track in the afternoon of Tuesday 9th is not ideal for us. I am proposing that we restrict our WG time to just the two morning sessions to avoid the timetabling clash. We can make a decision during lunch, based on our progress through the agenda by that time, about whether the afternoon P2P session is used or not.

We should name a PoC for these features so that interested parties have someone to contact that isn't a list. I would like to be the PoC for Recv_reduce/accumulate. If Cisco is not going to drive Arecv, I can be PoC there, otherwise, it should be Squyres or Goodell.

Hi All, I have a 10-minute slot to talk about the P2P WG during the MPI BoF at SC14.

Hi all, I have indicated to Martin that we will need/want 2 or 3 of the planned 1.5 hour WG sessions. We have new Recv_reduce and Arecv material from Jeff H and streams/channels feedback from the Japan Forum meeting. We have two teleconferences before the December meeting in San Jose but only one before the two week deadline for announcements of tickets/readings/etc. Please let me know as soon as possible if there are other topics to discuss at the meeting or if you can think of any reason we need plenary time.

I have no time for telecons before San Jose. Will be ready for the WG meeting though.

Hi Folks, Sorry for not following this more closely, but here are my thoughts (in no particular order): - Shouldn't the new send/recv functions use MPI_Count rather than int for the count parameter? - It would be nice if there was a no-copy mode, where the channel's buffer is returned to the user, and later returned to the MPI library. Rather than passing in a buffer in which to receive the data, the call would retrieve the address and length of received data. You'd need a second call to mark that data range "consumed" so that it could be reused. It's then up to the application to copy if appropriate, though it does change the semantics to byte stream (i.e. no datatypes) in this mode. - Should channel creation provide a hint in terms of the buffer size that should be allocated internally? - Having a way to "query" the internal buffer of the channel such that the application could use it directly, and avoid a copy on send, could be a nice feature.
