[ofiwg] DS/DA - Agenda for 8/2/16

Hi Chet - no problem.  The discussion on these topics was quite short.  For convenience, I am attaching the minutes from this morning's meeting - see the section toward the bottom labelled: "Resuming on 8/2/16" (I've been keeping this part of the minutes as a running commentary spanning the meetings where this has been discussed in order to keep the whole discussion in one place.)

See the note in there about taking your proposal to the larger OFI WG group for its review - you and I should work on scheduling that activity.  It is possible to schedule that for as early as next week if you are ready to do so.

Comments are, as always, welcome.

I apologize that I was not able to attend today to close on these topics.  I have been pulled in to another meeting at this time.

Perhaps we can discuss in two weeks?

Subject: [ofiwg] DS/DA - Agenda for 8/2/16

1.      Complete discussion of Intel's proposed OFA API extensions for RDMA

a.      'barrier' vs 'fence' - impacts on subsequent write operations?

b.      Ordering questions w.r.t. an explicit commit list.  Required ordering semantics?  Intel proposal requires commit and fence flags via separate write requests when writing to the same memory region (same R_KEY).  IETF draft, by comparison, uses an explicit commit list.

c.      Hopefully, Cray and NetApp will be available to discuss preferred approaches.
