[Mpi3-ft] Ticket 323 - status?

Wed May 30 18:59:49 CDT 2012

Since we went with the simplified FT proposal, there was some interest in seeing how upper-level FT libraries (that provide more useful semantics) would look like and how they would interact with applications. It was felt that some of these things might need more time to bake/mature before becoming a standard.

In addition, the issues that Darius and Martin have mentioned also a factor.

Hi George,

One other no was Intel as far as I remember, but I don't remember the 5th. However, I would suggest not to focus on the no votes alone. Several people who abstained had very similar concerns, but chose the abstain vote since they know it meant no, but they agreed with the general necessity of FT for MPI. I remember, for example, Bill saying that for him abstain meant no, but that changes later on could change his mind. Based on this interpretation, the ticket definitely had more than 5 no votes.

Argonne was not convinced that we (FTWG) had the right solution, and the large changes in the text mentioned previously did not instill confidence.  So it was decided that Argonne would vote against the ticket.

In total there were 5 no votes. I wonder who were the other two, they might be willing to enlighten us on their reasons to vote against.

Three no votes were LLNL, Argonne, and Sandia.  Since MPI is heavily driven by DOE, convincing these folks would be important.

The main objection raised is that the text has still been having large changes, and if not for the pressure of the 3.0 deadline, this would not have come up for a vote.  I talked one-on-one with many that either voted against or abstained, and this was the major (not only) point raised.

It seems we had very little, if any, technical opposition on the content of the proposal itself, but mostly comments on the process. I think we need to understand more what are the oppositions. Do we have a list of who voted for and against and their rationale?

That is unfortunate. A close vote (7 yes to 9 no/abstain). :/

Thanks,
