14 May '15

Hi Please consider joining the weekly Einstein Toolkit phone call at 10 am US central time on Mondays. As usual, you can find instructions how to join on the following web site: http://einsteintoolkit.org/community/support/ I short: the number is (+1) 225-578-4942 or (+1) 866-573-0359 and the conference id is 118682#.

benchmarks
by Steven R. Brandt 02 Dec '13

02 Dec '13

The utils/benchmarks contains a number of parameter files. All of them refer to thorns that are not part of the ET. I'm not sure where they might live. BenchIO BSSN_MoL FlexIO IOFlexIO whisky_init_data whisky whisky_rnsid Are these out of date? Are there better files to use for benchmarking? Cheers, Steve

Evolving grid arrays using MoL
by Ian Hinder 04 Nov '13

04 Nov '13

Hi, What is the current situation with evolving grid arrays with MoL? Over the past 7 years, this topic has come up repeatedly on the mailing lists, and some of the old information is probably out of date. Is there a way to do this without using any hacks, or are hacks still necessary? Is there an example somewhere of how to do this, or does someone have an example they would be willing to share? -- Ian Hinder http://numrel.aei.mpg.de/people/hinder

Fortran OpenMP parallel do
by Erik Schnetter 30 Oct '13

30 Oct '13

I have just found several instances of "OpenMP parallel do" constructs in GRHydro that did not mark loop variables as private. This is a severe parallelization error that can lead to wrong results in ways that are very difficult to debug. I wonder why the compiler does not flag this. I suggest a code review before the release. While it is true that the loop index of the loop that is parallelized (usually only the outermost loop) does, in Fortran, not have to be declared as private, all other loop indices still have to be declared as private. In C, all loop indices have to be declared as private. Personally, I find it simplest to just declare all loop indices as private. This is correct: !$OMP PARALLEL DO PRIVATE(i,j,k) do k=1,nz do j=1,ny do i=1,nx And this would be wrong: !$OMP PARALLEL DO do k=1,nz do j=1,ny do i=1,nx -erik -- Erik Schnetter <schnetter(a)cct.lsu.edu> http://www.perimeterinstitute.ca/personal/eschnetter/ My email is as private as my paper mail.

Meeting Minutes
by Roland Haas 30 Oct '13

30 Oct '13

Present: Erik, Frank, Roland, Ian, Steve Release date: * run testsuite by week of Nov 11th * aim for release before Supercomputing conference * Erik will start the tests on all machines, will then assign failing tests to maintainers * ask if Bruno Mundim would want to run on their machines in Frankfurt Restriction in Carpet: * commit patch to disable restriction into outer boundaries (which can never be fully filled via restriction) after release * add TODO item to optimize communication algorithm * deferred tickets ** #590 deferred to next release ** #1425 not release critical, remove milestone ** #980 deferred until after release ** #1429 patch applied, asked Bernard for exact intel compiler identification to add #ifdef to TP ** 1317 deferred until after release ** 809 deferred until after release ** 1251 deferred until after release, assign to Steve * those with patches will be added to trunk very shortly after the release * tickets for release ** Frank: apply conservative patch and disable for all intel 13 compilers starting from version known to fail. Backport more restrictive exclusion once we know of a known good version ** Roland: check if vectorization patch in PUGH needs to depend on Vectors (# 1411) ** Roland: apply first patch in #1395 ** Roland: remove OPTIONAL_IFACTIVE from #1411 ** Philipp: #1409 will include but add comment that Avec does not currently work ** Erik: #1360 (check if they even build, defer until after release) ** Ian: #626, #1075, #1387: delete faulty parfiles ** #1364 closed, suggest to require simfactories "make" option to be an executable with options. Needs to be documented. Running tests with different numbers of processors: * see comment in #1075 for decision on how to proceed if a test case asks for an explicit number of processes Yours, Roland

Present: Erik, Steve, Roland, Ian, Matt, Philipp Release date: * canonical Release milestones: * large number of tickets with milestone marker * introduce merge window before the release after which only minor changes are allowed * tickets to be deferred ** #590 deferred to next release ** #1425 not release critical, remove milestone ** #980 deferred until after release ** #1429 patch applied, asked Bernard for exact intel compiler identification to add #ifdef to TP ** 1317 deferred until after release ** 809 deferred until after release ** 1251 deferred until after release, assign to Steve * those with patches will be added to trunk very shortly after the release * assignments of tickets to maintainers, please have a look: ** Ian: #626, #1387, #1075 (interaction with simfactory, tentatively assigned) ** Roland: #1395 (apply patch), #392 ** Erik: #1360 (check if they even build, defer until after release), #1392 ** Philipp: #1409 will include but add comment that Avec does not currently work * check that tutorial still works, both the one for a workstation and the one on queenbee * further discussion on the mailing list * Ian will add description (based on email send to mailing list) on how to evolve arrays with MoL to wiki * Roland, Peter and Frank to provide examples for the gallery * check that parfiles from MHD paper work when downloaded from the website. Ideally one of the MHD paper authors other than Philipp or Roland (who ran most of them so are not good testers) Yours, Roland
