release tasks
by Frank Loeffler 09 May '15

09 May '15

Hi, Our goal is to release next week, at the beginning of next week if at all possible. This can only be achieved if we fix some things, and we agreed on working on it this week. Apart from an on-going discussion about include paths, we still have a long list of things to do. Since I might not have seen the progress on some points on this list I ask to report it here. What is left so far: - hwloc 'fiasco': we need to come to a state that builds for standard systems, for everyone who tries. Right now we have conflicting reports for Ubuntu. - include path trouble on multi-arch that might (mostly) influence users that need Fortran HDF5 support. We might suggest to build HDF5 in these cases. - regenerate thorns using Kranc (Peter): status? - test gallery examples (Frank): not done yet - tutorials (Frank): will be updated once release branches exist - Queenbee (Peter): was working on it, but is not in simfactory yet - Comet (Erik): fails too many tests - Supermuc (Bruno): any update on testsuites? - Fermi & Galileo (Italian machines, Frank): testsuites all pass, simfactory entries will be added soon - mike: updated configuration exists, but was causing trouble for Erik for unknown reason that couldn't be reproduced. At this point I would have loved to create release branches. With the current status we shouldn't. We need a little of everyone's time to make this release happen. See if you can find something to help moving things along, and if that isn't something for you, give a fresh checkout a try, to see if that works as it should on your machine. Frank

Reverted changes to Mike Simfactory entry
by Erik Schnetter 07 May '15

I've reverted the recent changes to Mike's Simfactory entry. With these changes I saw build failures. -erik -- Erik Schnetter <schnetter(a)cct.lsu.edu> http://www.perimeterinstitute.ca/personal/eschnetter/

ET Meeting Minutes
by Frank Loeffler 04 May '15

04 May '15

Hi, Present were: Bruno, Eloisa, Erik, Frank, Ian, Matt, Peter, Steve, and Zach. Zach mentioned that once the release is done he would like to get the Illinois MHD code into the ET as fast as possible. The necessary changes to Carpet have already been made (staggered operators). Bruno mentioned that it might be beneficial to have the determinant of the metric as extra GF because it might/is used in a lot of places. Performance tests would need to be done to see what the impact of that would be. Bruno also would like to see a function that would return, in some form or another, the checked out version of the ET - to be used in some of his code. It was suggested to introduce this in EinsteinBase, after the release. Ian mentioned that lately he has trouble running out of memory, although Carpet doesn't report increased usage. He sees signs of memory fragmentation and is interested to know if others see similar problems. Peter did performance tests of the rewrite branch of McLachlan, and found at most a few percent slowdown. However, some interesting parameter setting haven't been tested by this yet. Release details: Relevant wiki page: https://docs.einsteintoolkit.org/et-docs/Release_Details Release time frame: get everything possible done _this week_, release next week. Thorns generated by Kranc will be checked/regenerated by Peter. The test gallery examples will be tested/updated by Peter and Frank. Frank will also update the tutorials, where necessary. We will also need to consolidate all the tutorials that have been written at some point, and in some cases got forgotten. Results from automated tests can be found here: https://build.barrywardell.net/view/EinsteinToolkitMulti/job/EinsteinToolki… Queenbee will be added to this list, once a suitable configuration is generated (Peter), the same holds for Comet (Erik). Supermuc is unlikely to be added to that list, but will be tested manually by Bruno. Stampede-mic is (still) not working, and will not be part of the release. Pandora also shows a lot of failures, and due to its age and decreased interest will be dropped. Systems with a few failures will be looked at: mike (Peter), shelob (Frank) Standard machine files that will be tested are: - Debian (Frank) - Ubuntu (Bruno) - Fedora (Steve) - Mac OS (Erik & Ian) The release name will be "Hilbert".

Release machine tests
by Ian Hinder 04 May '15

04 May '15

Hi, There is a table of test results generated automatically after runs of the tests on many machines for the release. The tests are initiated by Erik, and then the results are automatically uploaded to this system: https://build.barrywardell.net/view/EinsteinToolkitMulti/job/EinsteinToolki… This provides a slightly different view of the results than the "official" page. -- Ian Hinder http://members.aei.mpg.de/ianhin

Optimised CarpetInterp2 interpolation
by Ian Hinder 04 May '15

04 May '15

Hi, I just created a ticket describing an optimisation to CarpetInterp2 which should be beneficial to people using multipatch: https://trac.einsteintoolkit.org/ticket/1771 -- Ian Hinder http://members.aei.mpg.de/ianhin

meeting minutes for 2015-04-27
by Roland Haas 01 May '15

01 May '15

present: Frank, Jonah, Roland, Josh, Ian, Erik, Christine Corbett-Moran (Caltech), Elo Mailing list issues: * affected users were set to "bounced" status * Frank suspects this was because CCT changed firewall rules ET release: * recursive dependency between MPI and hwloc due to routines in the thorn itself (not in the distribution tarball) * accepted solution: move respective routines into SystemStatistics thorn * add -lnuma to all linux based option lists * Erik to try and see if his testing scripts still runs, will use current einsteintoolkit.th from fro development branch * local machines/linux/osx should be tested now as well * ssl certificate of jenkis build machine is invalid, Ian will look into this (domain is owned by Barry Wardell) Stampede: * no updates * need to decide on which compiler to use for release testing * Ian thinks that second maintenance should have brought in intel 15 * Caltech has an allocation, Christine will try and follow up locally to see if someone has already used it and could give intel 15 a try Yours, Roland

Frank's announcement that he is preparing a new ET release, and that there is currently a feature freeze, may or may not have made it to the mailing list. FYI: The semi-automated ET tests currently include Blue Waters, Carver, Datura, Edison, Gordon, Hopper, Mike, Pandora, Philip, SHC, Shelob, Stampede, Trestles, Zwicky, as well as a few internal workstations. See < https://build.barrywardell.net/view/EinsteinToolkitMulti/job/EinsteinToolki… >. -erik -- Erik Schnetter <schnetter(a)cct.lsu.edu> http://www.perimeterinstitute.ca/personal/eschnetter/
