Re: [Mpi-forum] MPI Forum Virtual Meeting Videos

Hearing no objections, I’ve moved all of the videos over to YouTube. Note that these videos are unlisted, so you won’t be able to search for them on YouTube itself. You’ll have to find them through the MPI Forum website: https://www.mpi-forum.org/virtual_meetings/ <https://www.mpi-forum.org/virtual_meetings/> Thanks, Wesley > On Feb 20, 2020, at 6:12 PM, Wesley Bland <work(a)wesbland.com> wrote: > > Hi all, > > During the meeting this week, I brought up another housekeeping item that’s come up recently.

MPI Forum Virtual Meeting Videos
by Wesley Bland 20 Feb '20

20 Feb '20

Hi all, During the meeting this week, I brought up another housekeeping item that’s come up recently. We typically record our virtual meetings and the recordings are kept in the Webex account of the Webex host (either Jeff or myself). However, this can cause a problem going forward as our available space fills up or if we were to lose access to the account (e.g. if either of us left our current job in the future). At the meeting, we agreed that we do want to preserve these recordings as they remain useful to us, but we were concerned about the logistics of how to preserve them. There was a suggestion that we could upload them to YouTube to make it easy to host these long term without worrying about hosting requirements. We could also make these unlisted videos and post the links on our website to keep essentially the same level of privacy that we already have. Before I start uploading all of the videos, I wanted to give those who are not in the room a chance to provide feedback. Does anyone have an objection to uploading our videos to YouTube going forward? If I don’t hear any objections by next week, I’ll assume it’s ok to moving the videos over from Webex to YouTube. Thanks, Wesley

MPI Standard Consistency Changes
by Wesley Bland 19 Feb '20

19 Feb '20

Hi all, As I discussed in the plenary during today’s face to face, there is a long list of consistency and correctness changes being proposed by Bill Gropp as part of his role as document editor. He’s asking for both guidance and assistance to accomplish these things. You can help in two ways: 1. Go through the poll to express you opinion about how each of the items should be handled. Some will be small (editor / ticket 0 changes). Some will be larger (requiring a full proposal and votes). You can do that here: https://forms.gle/kgdm3B21uNnA5Y6a9 <https://forms.gle/kgdm3B21uNnA5Y6a9> This is a long list so you may not be able to finish it in once sitting. Feel free to do as much as you have time for, submit that, and then finish later from wherever you left off. 2. As you’re going through that poll, please be willing to take a few issues as things you can help drive. Each question in the poll has an issue number listed with it. You can find the matching issues here: https://github.com/mpi-forum/mpi-issues/issues <https://github.com/mpi-forum/mpi-issues/issues> This is a great way to get involved with the forum if you’ve never had driven a proposal before. In most cases, both the problem and solution is already written out for you. Many of the issues are also tagged with specific chapter committees or working groups who should probably be involved. Feel free to go to an issue on GitHub and leave a comment saying that you’d like to take it. I can assign it to you once you’ve done that. There’s a lot to do here and we all benefit by getting a higher quality document if this work gets accomplished. Thanks in advance for those of you who take the time to contribute both by taking the poll and picking up an issue. Please go through this poll by March 20th so we have time to plan for the MPI 4.x timeline. Thanks, Wesley

Hi all, As I mentioned in the MPI Forum meeting today, we have had a Slack for the MPI Forum for a while that has been used by some, but not everyone was aware of it.
