Next MPI Forum meetings
by Martin Schulz 24 Sep '13

24 Sep '13

Hi all, During the last forum meeting in Madrid, we discussed dates and locations for the meetings in 2014. The non-US meeting will be in September in Kobe, Japan (at Riken) close to "Euro"MPI, which is held in Kyoto (the consensus was that we rather switch locations to Kobe - 1 hour by train - rather than stay in Kyoto, since RIKEN can host the meeting for significantly less cost). For the remaining meetings we will alternate between San Jose and Chicago as usual. As for the dates, the following dates seem not to have major conflicts: March 3-6, 2014, San Jose June 2-5, 2014, Chicago September 15-17, Kobe (after "Euro"MPI, which ends Friday) The only alternative here would be to run it the week before, but that would lead an additional day as gap December 8-11, San Jose Note, we also decided last June to change the meeting times (for US meetings) to starting at 2pm on the first day and ending before lunch on the last day, to allow people to fly in from either coast on the same day. If we have a lot of agenda items, we will make up time by meeting until later (7pm worst case). I hope this makes the Monday starts more palatable and allows us to stay off Friday, which is an off day for some. Non US meetings will continue to be three full days. We have meeting rooms for all meetings - please check if these dates overlap with any major events or cause any substantial conflicts. If I don't hear any major complaints by Oct 11th, I'll consider the dates fixed and I'll remove the tentative from the website. Thanks!

New Logo for the MPI Forum
by Martin Schulz 14 Sep '13

14 Sep '13

Hi all, It's long overdue that we use a new logo for the MPI forum - in case you haven't looked at the forum website in a while, it still says MPI-2. At the forum meeting in Madrid we decided on the following process (to make sure we drive this forward). Anyone who has a suggestion for a new logo, please send it to me (until 2 weeks before the meetings). I will collect all of them and then send them to everyone for comments. We will then vote at the next forum meeting in Chicago and pick one. Currently, we have two proposals on the table (created by the UTK folks a while ago - thanks!) - those are attached - but the more choices we have the better. Get creative … :) Martin

Please post this to the appropriate list, e.g. users(a)open-mpi.org, discuss(a)mpich.org, etc. This email list is for discussing the MPI standard. I know the answer to your question but will only post it in response to a query on the appropriate list.

Wed logistics
by Richard Graham 09 Sep '13

09 Sep '13

Just to let folks that will be around on Wed that even though nothing formal is planned, we could not change the pre-arranged logistics. Those that are around can benefit from the meal we have already paid for. I believe this is to be served in the hotel restaurant. Rch
