Hello All, I wanted to make sure I/we are not missing important alternate MPI fault tolerance approaches. Keita had earlier pointed me to the Fault Aware MPI effort by Tony Skjellum et al. (I am not sure if his team members are on this mail alias), and I started reading their 2015 paper "Practical Resilient Cases for FA-MPI, A Transactional Fault-Tolerant MPI" again. It's an interesting approach, although I am, of course, very concerned about regular collective calls to corral faults, and also about the need to constrain applications to using non-blocking communications only. Is there any information/insight into how seriously this approach is being pursued for inclusion in the MPI standard? Thanks.

That's OK, we are not only fault tolerant, but also latency tolerant.

Yes, I should be able to do that. I may be around 5 minutes late though.

Hi FTWG,

If I'm not mistaken, we have an FTWG con call today. On the agenda is continuing the discussion of the concerns around ULFM. Ignacio, are you ready to present the Reinit slides you had a month or two ago while I was out?

Here's the call-in information:
