[Mpi-forum] Notes on discussions about 3.0 / 3.1?

[Jeff Hammond]

Perhaps since MPI 3.0 got everything right that it attempted to do :-)
then we can skip 3.1 and move onto to 4.0, the most nonblocking-est,
fault-tolerantest MPI ever!

One of the things suggested was that we have a day in  between meetings for voting, doing this over the phone, but with attendance at the regular meetings continuing to determine voting elegibility.

Chapter authors that don't participate would be replaced by others that will help get the revised text into the draft standard. (2) The July Chicago meeting will be devoted solely for getting the draft standard into final form.  Last second votes will take place on Monday, with the rest of the time dedicated to chapter committee work.  (3) The draft standard will be posted for public comment after the meeting, giving people time to comment before the final votes in Vienna.
