Dear all, I am on travel from EuroMPI tomorrow, and I suspect it's not just me, so we will skip this weeks call on performance topics.

PMIx questions
by rhc＠open-mpi.org 25 Sep '16

25 Sep '16

Hello folks I appreciated the questions raised at last Thursday’s debugger meeting regarding PMIx. While I’m sure Kathryn will publish great notes, I thought I would try to address some of those questions on the PMIx web site. I also took the opportunity to update that site a bit to clarify the intended role of PMIx. You can find the web site here: https://pmix.github.io/master Further answers to the questions raised at the meeting can be found here: https://pmix.github.io/master/faq/ I will strive to continue updating the site over the coming weeks - the PMIx community is trying to polish it up a bit for Supercomputing, but implementation always takes priority :-) Ralph

Meeting reminder - performance tools
by Marc-Andre Hermanns 15 Sep '16

15 Sep '16

Hi all, This is your friendly reminder of our regularly scheduled Tools WG call *today* at 11 a.m. EDT. This week's focus is performance tools. The link is here: https://cisco.webex.com/ciscosales/j.php?MTID=m0fb3e4a68162bff5874849e4700b… I didn't get to writing the text for the standard yet, but updated the current state of the interface (attached) according our discussion last time. Today, I just want to make sure if this is really what we discussed and more importantly what we want. ;-) Also, please write me an email if you still need access to the repository for the MPI_T event header file. I will send you an invitation. Looking forward to talking to you. Cheers, Marc-Andre -- Marc-Andre Hermanns Jülich Aachen Research Alliance, High Performance Computing (JARA-HPC) Jülich Supercomputing Centre (JSC) Schinkelstrasse 2 52062 Aachen Germany Phone: +49 2461 61 2509 | +49 241 80 24381 Fax: +49 2461 80 6 99753 www.jara.org/jara-hpc email: hermanns(a)jara.rwth-aachen.de

MPI Forum Web/Mailing List Migration Update
by Bland, Wesley 06 Sep '16

06 Sep '16

TL;DR - The DNS records for the MPI Forum will be moving from Illinois to Google tonight<http://airmail.calendar/2016-09-06%2019:00:00%20CDT>. This should have user impact, but it’s possible that there will be a short outage depending on your local DNS caches. Other services will be migrating soon. More Details - As part of the overall migration process that I referenced in an email about a month ago, we’re moving the DNS records out of the University of Illinois and up to the cloud (in this case, Google Domains). This should have no impact on your ability to view websites or send emails to these mailing lists, but it’s possible that as the new DNS information propagates to all of the caches around the world, there will be some brief outages. For now, nothing should change. If everything goes well tonight<http://airmail.calendar/2016-09-06%2019:00:00%20CDT>, I hope to start migrating services next week (with the intention of having everything migrated before the 14th<http://airmail.calendar/2016-09-06%2012:00:00%20CDT> so we can make sure everything is stable for EuroMPI and the September MPI Forum meeting. Here is the rough timeline: Sometime this week - Move DNS records from UIUC to Google (hard to predict exactly when this happens) This week - Prepare mailing lists (moving from Indiana to Argonne) and website (website preview available at https://mpi-forum.github.io/) for move. Early next week - Move mailing lists and website to their new hosts September 14th<http://airmail.calendar/2016-09-14%2012:00:00%20CDT> - Migration complete (anything not migrated will be postponed until after the EuroMPI/MPI Forum meeting) If you have questions/concerns about the migration, new website, mailing lists, etc., please let me know. Thanks, Wesley
