I posted a new version of the document on the forum Wiki. I have available a version that contains -all- the changes, including the renaming (agreement->agree, invalidate->revoke, return an error->raise an error) if you want to see it, but it is mostly clutter.

by Josh Hursey 21 May '12

21 May '12

We are a week out from the MPI Forum meeting and the first vote on the User-Level Failure Mitigation proposal. As such we have set some hard deliverables for today (Monday). Namely: - Circulate final ticket 0 edited text to MPI Forum - Make prototype implementation available Additionally, this week we should start reviewing the slides to be presented at the forum. I think George Bosilca is taking the lead on this. I will put this on the agenda for our Wednesday teleconf. I can work on making a distrition release of the prototype today. UTK, can you circulate the final version of the ticket text? Thanks, Josh -- Joshua Hursey Postdoctoral Research Associate Oak Ridge National Laboratory http://users.nccs.gov/~jjhursey

Yes. That's just a problem because the size of the edit is so large. Once the ticket0 changes go away it looks fine. Unfortunately there's not a lot I can do to fix that at the moment.
