Sorry for my late reply.
And thank you all for your answers and comments.
Oleg,
Same question as Aurélien. You mentionned that you have implemented some
piggyback mechanisms in Open MPI.
Are these mechanisms available ?
Would it be possible to use it ?
Regards.

Thank you Josh, that's interesting. I'll have a look.

Oleg,
Is there an implementation in Open MPI of your techniques ? Can we put
our greedy nasty pawns on it ?
Thanks for the link, Josh.

Oleg,
Interesting work. You mentioned late in your email that you believe
that adding support for piggybacking to the MPI standard would be the
best solution. As you may know, the MPI Forum has reconvened and there
is a working group for Fault Tolerance. This working group is

Hi,
I've been working on MPI piggyback technique as a part of my PhD work.
Although MPI does not provide a native support, there are several different
solutions to transmit piggyback data over every MPI communication. You may
find a brief overview in papers [1, 2]. This includes copying the origi
I don't know of any work in that direction for now. Indeed, we plan to
eventually integrate at least causal message logging in the pml-v,
which also includes piggybacking. Therefore we are open for
collaboration with you on this matter. Please let us know :)

Hi,
I'm currently working on optimistic message logging and I would like to
implement an optimistic message logging protocol in OpenMPI. Optimistic
message logging protocols piggyback information about dependencies
between processes on the application messages to be able to find a

Hi,
I'm developing a causality chain tracking library and need a mechanism to
attach an extra data to every MPI message, so called piggyback mechanism.
As far as I know there are a few solutions to this problem from which the
two fundamental ones are the following:
- Dynamic datatype wrapping
