[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.
