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.

Hi all, After saying that I thought I would be available on July 12th to move forward the plenary, it turns out that I will be in an all-day meeting that day after all. I can meet the following week (July 19th) if that works for people. Otherwise I can cancel and we can do it on July 26th. What do people prefer? Thanks, Wes
