by Martin Schulz 30 Nov '22

Hi all, As announced last week, we’ll have an MPI virtual meeting today at 10am US CT, in which Aurelian will cover ULFM Part 2. The link is in the usual place on the forum website. Thanks!

Re: [Mpi-forum] Upcoming Meeting Schedule for the MPI Forum

I don’t see any major conflicts. Perth as a virtual meeting is going to be rough, because Europeans will be waking up around 2 AM and people in the New World will be working in the evening and into the night. It’s also the longest flight one can take from North America. It’s less than the flight time for Apollo 11 to get to the moon, but close.

Upcoming Meeting Schedule for the MPI Forum
by Martin Schulz 23 Nov '22

23 Nov '22

Hi all, We need to discuss the schedule for the upcoming meetings in 2023/24. Formally, we will decide on this during the MPI forum meeting, but I wanted to send out the following proposal ahead of time, so everyone can check for major conflicts and or other issues. Note, we decided to hold the spring meeting in person/hybrid (preferably ET/CT), summer and winter fully virtual and Fall together with EuroMPI (and keep co-locating EuroMPI and IWOMP). For the spring meeting, we have an offer to host this in Boston – location and dates are confirmed: Spring Meeting: March 13 to 16, 2023, Boston (AWS Offices, thanks Quincey) Start noon, end noon Assuming we finish all final reading in that spring meeting, and we want to hit SC for MPI 4.1, we need two voting meetings instead of one summer meeting (both virtual): Suggestions (decent spacing plus avoiding summer conflicts, I hope): May 1 to 4, 2023, virtual Could be fewer days if votes are the core items July 10 to 13, 2023, virtual Could be fewer days if votes are the core items The fall meeting will be with EuroMPI in Bristol – this will be the RCS meeting (the one we read the entire standard page by page – hence, onsite will make things a lot easier): Fall Meeting: September 13-15, 2023, Bristol (right after EuroMPI, parallel to IWOMP) Three full days Again, assuming we intend to hit SC23 for MPI 4.1, we need an additional voting meeting. Suggestion: two weeks before SC23 October 31 to November 3, 2023, virtual Could be fewer days depending on agenda Starting after SC23 we would be back on a normal schedule: Winter Meeting: December 4-7, 2023, virtual Spring Meeting (space reserved): February 26-March 1, 2024, Chicago (Big Ten Center in Chicago, thanks to Maria and Bill) Start noon, end Noon Summer Meeting: June timeframe, virtual Let’s wait for 2024 summer conflicts before fixing dates Fall Meeting: September, again with EuroMPI and IWOMP Location would be Pawsey Supercomputing Center near Perth, Australia (the location was already picked by IWOMP - I know this is a stretch for many, but we will have a hybrid option and it would help cover an area that is traditionally underrepresented in the forum and – especially – the conference) Please take a look at the dates and send me any information about major conflicts.

Hi Jeff, This just means changes were made since the reading on the respective issues. If the No No passes, then we proceed to the first vote. If it fails, we either vote on the issue/PR without these changes or (more likely) restart the reading process, as the changes are deemed too large for the No No process.

Hi Wes, I believe we're missing a no-no-vote for issue #429 (RMA: Replace 'operation' with 'operator' where appropriate), which had changes since the first reading. The rest looks good from our side.
