[Mpi3-ft] MPI_ERRORS_ARE_FATAL clarification ticket
by Josh Hursey 27 Feb '12

27 Feb '12

We extracted the 'fatal subgroups' clarification into a separate ticket. I would like to read it during the next meeting. Can I get some reviewers for this small ticket? https://svn.mpi-forum.org/trac/mpi-forum-web/ticket/324 Thanks, Josh -- Joshua Hursey Postdoctoral Research Associate Oak Ridge National Laboratory http://users.nccs.gov/~jjhursey

Re: [Mpi3-ft] [Mpi3-rma] Fault Tolerance & RMA Discussion
by George Bosilca 22 Feb '12

22 Feb '12

Based on the discussion and opinions expressed during this call, the new FT proposal has been amended to include RMA operations. The FT model for windows is similar to the point-to-point mode: break nothing by default, provide tools to the user level to break and fix the issues. Thus, on group based operations only ranks directly involved in RMA operations with failed processes will be notified. A special function (MPI_Win_invalidate) is available to mark the window as improper to RMA operations, other wise (and this with few restrictions) further RMA not including the failed processes should proceed as expected in a failure-free execution. The current version if the FT proposal is attached to this email, and can be accessed in the working group wiki @ https://svn.mpi-forum.org/trac/mpi-forum-web/wiki/User_Level_Failure_Mitiga…. We expect to have a final version of the proposal by Monday noon EST, as requested by the MPI_Forum to be able to have a first reading at the next meeting. We are looking forward to your comments. george.

The feeling seemed to be that the current approach is ok (invalidating the window, forcing recreation/validation), but the statement that the memory exposed in the window is 'undefined' seemed excessive. The suggestion was to change the wording to something like "Only the memory associated with a window that was targeted by an operation that modified it is undefined after process failure in the group associated with the window." This lead to a considerable amount of debate in the meeting, so it was suggested that we take the discussion offline. > > Below is a link to a doodle poll to find a good time for a teleconf.

Re: [Mpi3-ft] [MPI3-IO] Fault Tolerance & I/O Discussion
by George Bosilca 22 Feb '12

Based on the discussion and opinions expressed during this call, the new FT proposal has been extended to include wording about the I/O. The model for I/O is very synchronous, providing a single function related to I/O. This function can be used to invalidate a file, preempting any subsequent operation on it. The file will then have to be closed, and is necessary reopened based on a new communicator (a smaller version of the original one). The current version if the FT proposal is attached to this email, and can be accessed in the working group wiki @ https://svn.mpi-forum.org/trac/mpi-forum-web/wiki/User_Level_Failure_Mitiga…. We expect to have a final version of the proposal by Monday noon EST, as requested by the MPI_Forum to be able to have a first reading at the next meeting.
