Re: [mpiwg-ft] [Mpi-forum] FTWG Con Call Today

      Thanks Ignacio, I'd be very interested in learning how that approach works. Especially the "goes always back to the resilient_function call 1" part, without adding another branch on the call stack?

The model is that the app goes always back to the resilient_function call 1 (we cannot call this function twice or more statically in the program). Perhaps we can discuss that again.

There was another question that came up in internal conversations 
around here with Reinit:
What's going to happen to the call stack. E.g. MPI_Init -> ... -> 
resilient_function call 1 -> Failure -> ReInit - resilient_function 
call
2 -> End of Work -> back to resilient_function call 1?

That works for me (I couldn't attend today neither).
We are almost done with the new Reinit spec but we have a few topics we
    would like to discuss in the group: (1) using several error handlers
    and
    how this is specified in the standard, (2) the state of MPI between a
    failure and its recovery (how does ULFM does it? Perhaps Reinit can
    re-use the same text?).
Thanks!
