Hello folks I have (finally) written a description of the PMIx event notification system. Please see the wiki page here:
https://github.com/pmix/master/wiki/2.9-PMIx-Event-Notification <https://github.com/pmix/master/wiki/2.9-PMIx-Event-Notification> This is the same event notification method we will be using inside OMPI (I am working on implementation now). I would appreciate any feedback on it - and hope it provides at least some clarity to the picture. Ralph
