[Mpi3-ft] Mission statement and assumptions
by Graham, Richard L. 31 Aug '09

31 Aug '09

Here is the summary of what we agreed to on the last call: Mission Statement: Ensure the survivability of the functionality of the MPI library in the face of failures and help the programmer build reliable applications by providing additional hooks needed. Assumptions: - Users can specify if they want the MPI library to support MPI fault-tolerance - MPI should restore it's internal state to a consistent state and report any problems if there is a fault. - This allows for fast unreliable MPI on reliable hardware. - MPI fault tolerance features do not handle user data - MPI 3.0 should work the same as MPI 2.2, if no fault-tolerance features are used. (backwards compatible) - MPI should have minimal impact on application performance when no failures occur. - MPI should handle transient and fail-stop faults. We will not handle Byzantine faults Comments ? This will be the basis for some of the discussions in Helsinki this week. Rich
