Hi all, As discussed at the forum meeting in Zurich, we will again have as series of virtual meetings (at the usual time, Wednesday 10am CT) to prepare for readings in September in Albuquerque. We will schedule the topics for these meetings a bit more dynamically as usual. It would be great if as many as possible could attend these meetings (or provide feedback based on the recordings, which we will post), to avoid surprises in December. For the meeting this week, we will focus on new text covering the remaining major points from Sessions, the ticket covering MPI_INFO_ENV before Init, and - if there is time left - tool UIDs. Looking at MPI 4.0, the most anticipated/requested features (and also the ones we advertised the most) are Sessions and BigCount. Hence, the ensure that those two are ready for the December meeting, these topic will get preference in the upcoming virtual meetings, other topics will be scheduled as needed and based on availability and readiness, but we will likely run out of meeting times (we have only until SC19 before the two week deadline). We will keep a list of possible topics on the website - currently this includes (in particular order): - Semantics and Terms - Partitioned Communication - Procedures document - HW Split Type - Cartesian/Halo Communicators (If I missed one, please let me know) Note, though, that this doesn’t mean other topics can’t and shouldn’t make progress or can’t be ready for the December meetings. The respective WGs should try to incorporate the forum feedback and update the respective tickets. Also, if forum feedback is needed, please free to use the email list or invite others to the WG meetings. I hope this all makes sense - if there are any concerns, please let me know. Thanks!
