Thomas,
We are working on this topic at the University of Tennessee. In fact,
2 of the MPICH-V guys are now working on Open MPI on fault tolerant
aspects. With all the expertise we gathered doing MPICH-V, we decided
to take a different approach and to take advantage of the modular
architecture offered by Open MPI. We don't focus on any specific
message logging protocol right now (but we expect to have at least
all those present in MPICH-V3). Instead what we target is a generic
framework which will allow researchers to implement in a simple and
straightforward way any message logging protocols they want, as well
as providing all tools required to make their life easier.
The code is not yet in the Open MPI trunk but it will get there soon.
We expect to be able to start moving the message logging framework in
the trunk over the next month.
Thanks,
george.

Dear all,
I am currently working on a fault tolerant protocol for message
passing
applications based on message logging.
For my experimentations, I want to implement my protocol in a MPI
library.
I know that message logging protocols have already been implemented in
MPICH with MPICH-V.
I'm wondering if in the actual state of Open MPI it is possible to do
the same kind of work in this library ?
Is there somebody currently working on the same subject ?
Best regards,
Thomas Ropars.
