[mpiwg-ft] FTWG Call Today

[Van Der Wijngaart, Rob F]

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.

Rob
