[mpiwg-ft] FTWG Con Call Today

[Ignacio Laguna]

Hi Wesley, all,

If we have time when we meet again, I'd like to add to the agenda tools 
support for the Reinit spec. Here's a new version (0.2) of the Reinit spec:

     https://reinit.github.io/reinit/docs/reinit-0.2.0.pdf

We added a section on tools. The main question we have is what happens 
with performance variables after we resume execution at the rollback 
point: should the MPI implementation reset the variables or should the 
tool adjust its values of the variables taking into account failures? My 
preference is that MPI resets the variables, but we would like to hear 
opinions.

In any case, we are thinking to propose a perf variable that reflects 
the failure counts that tools can use. We could also propose an event 
triggered after rollback occurs.

Ignacio
