I just updated the proposal with the following: - Collective examples (barrier, bcast, gather, scan, exscan) - Initial pass at wording for Ch. 6 Groups, Contexts, Communicators, and Caching - Moved the validate functions to Ch. 6, where they should reside - General cleanup, example fixes I think the Ch.6 changes will need some discussion, and is what I hope to discuss next week for those at the forum. For those not at the forum next week, I'll leave some time on the teleconf to discuss this as well. -- Josh On Sep 8, 2010, at 10:47 AM, Joshua Hursey wrote:

I just updated the run-though stabilization proposal on the wiki with some more language for the collective operations and nonblocking variants of the collective validate functions.

I'm working on a few collective examples at the moment.

I recently started to generate a proposal to support applications that wish to run-through process fail-stop failures. This is an attempt to pull apart the current FT proposals into two camps: stabilization, and recovery. The run-through stabilization proposal is meant to provide the foundation for and a complement to an eventual recovery proposal.

The run-through stabilization proposal aggregates much of the discussion in the working group so far regarding error management and validation of communicators. I modified some of the interfaces based on some recent experimentation with the interfaces. I have also been reading through various parts of the standard to find semantics, interfaces, and discussions that will need to be modified in order to support run-though stabilization.

The current draft on the wiki is rough and in development. I have a few more notes and changes to make, but I wanted to circulate the current state before the teleconf tomorrow. This way I can introduce the proposal and we can start discussing some of the concepts. My hope is that this proposal helps spark some more discussion in the working group.

The proposal is linked off of the main FT working group wiki, and is at the link below: https://svn.mpi-forum.org/trac/mpi-forum-web/wiki/ft/run_through_stabilizati...

Concurrently with the development of the proposal text, I am working on a prototype implementation in Open MPI that should help guide the process of refining the proposal.
