I plan to go over this during the con call next week, but if you’d like to get a preview and/or comment early, I have a draft of the slides for the reading for ticket #324. You can view the slides here: https://docs.google.com/presentation/d/10Sz9aCDezSLH1rss6XYApo_wVqTyHH08G3FU... If you have any questions/comments, let me know. Aurelien, I’m not sure of the status of this ticket in Open MPI. Is there a way to keep Open MPI from aborting on any error in the trunk? Is the only way to get this in the ULFM repo? Thanks, Wesley
