Thanks, Howard. If we want to take a slot for the FT group, Tuesday starting at 9am works best for me (except I will only be able to stay for about 1.5 hours).

Hi Ignacio, Next week is the forum. Sounds like we're going to be using chunks of time for WG meetings. We could discuss this in the sessions WG slot 9-13 2/28, or there are still two slots open if the FT group wants to claim one of those.

Hi all, I have clarified what happens with MPI and Session objects after a failure in the coarse-grained model (Reinit) and I pushed the changes to the ft-reinit branch in the FT repo. Should we have a time slot next week to discuss the FT proposals? The same time as usual works for me: Monday at 9-10am Pacific. Thanks!
