Compiling Ørsted with OpenMP and gcc-4.7.2
by David Radice 13 Nov '12

13 Nov '12

Dear ET users, I am trying to compile the latest release of the Einstein Toolkit, Ørsted, on my laptop (Fedora 17, gcc-4.7.2), but I get the following error if I try to compile with OpenMP: /home/davide/Desert/CactusOersted/configs/charon/build/Carpet/Recompose.cc:2071:2: error: stray ‘#’ in program the error disappears if I compile with no OpenMP support. I can also compile without problems, using the same thornlist and with OpenMP support, on our local cluster with the Intel compiler. It looks like a compiler bug to me, but I am not sure about what exactly is triggering it... Do you have any idea of what could be going wrong? Cheers, David -- http://numrel.aei.mpg.de/people/radice

Einstein Toolkit Meeting
by Frank Loeffler 11 Nov '12

11 Nov '12

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#. After the Ørsted release last week [1] development is again open and we will discuss what to tackle next, e.g., what we plan to include in the release next spring. There are still some issues to be looked at in terms of MHD. Also, some tickets have been postponed for the next release, mostly because it was too late to fix them for the current one. Now would be the perfect time to look at these: [2]. As an afterthought, the release and the developers workshop again produced a nice 'dip' in the number of open tickets and a corresponding increase in closed tickets. The about half-yearly release cycle is quite visible in these numbers and shows the importance of doing the releases [3]. Having said that, currently 13 tickets are awaiting review [4]. Please consider looking at one of them to help getting it closed.

New release of the Cactus Computational Toolkit
by Frank Loeffler 08 Nov '12

08 Nov '12

We are pleased to announce release 4.1.0 of the Cactus computational toolkit. This release includes support for new architectures, changes to MPI configuration and comes bundled with supporting tools like GetComponents and Simfactory. In addition, bug fixes accumulated since the previous release in October 2011 have been included. This release was tested and released together with the sixth release (code name "Ørsted") of the Einstein Toolkit [1], and is used by that. For more detailed information about the 4.1.0 release please read the long release announcement on the Cactus Toolkit web pages: http://cactuscode.org/download/releasenotes/Cactus_4.1.0 On behalf of the Cactus release team, Frank Löffler [1] http://einsteintoolkit.org/about/releases/ET_2012_11_announcement.php

Einstein Toolkit Release
by Frank Loeffler 08 Nov '12

08 Nov '12

We are pleased to announce the sixth release (code name "Ørsted") of the Einstein Toolkit, an open, community developed software infrastructure for relativistic astrophysics. This release includes various improvements to the MHD handling within GRHydro, and improvements to the Cactus flesh. In addition, bug fixes accumulated since the previous release in May 2012 have been included. The Einstein Toolkit is a collection of software components and tools for simulating and analyzing general relativistic astrophysical systems that builds on numerous software efforts in the numerical relativity community including CactusEinstein, the Carpet AMR infrastructure and the relativistic hydrodynamics code GRHydro (an updated and extended version of the public release of the Whisky code). The Cactus Framework is used as the underlying computational infrastructure providing large-scale parallelization, general computational components, and a model for collaborative, portable code development. The toolkit includes modules to build complete codes for simulating black hole spacetimes as well as systems governed by relativistic hydrodynamics. The Einstein Toolkit uses a distributed software model and its different modules are developed, distributed, and supported either by the core team of Einstein Toolkit Maintainers, or by individual groups. Where modules are provided by external groups, the Einstein Toolkit Maintainers provide quality control for modules for inclusion in the toolkit and help coordinate support. The Einstein Toolkit Maintainers currently involve postdocs and faculty from six different institutions, and host weekly meetings that are open for anyone to join in. Guiding principles for the design and implementation of the toolkit include: open, community-driven software development; well thought out and stable interfaces; separation of physics software from computational science infrastructure; provision of complete working production code; training and education for a new generation of researchers. For more information about using or contributing to the Einstein Toolkit, or to join the Einstein Toolkit Consortium, please visit our web pages at <http://einsteintoolkit.org>. The Einstein Toolkit is primarily supported by NSF 1212401/1212426/1212433/1212460, 0903973/0903782/0904015 (CIGR), and also by 0905046/0941653 (PetaCactus) and 0710874 (LONI Grid). The Einstein Toolkit contain over 170 regression test cases. On a large portion of the tested machines, all of these testsuites pass, using both MPI and OpenMP parallelization. All repositories participating in this release carry a branch ET_2012_11 marking this release. These release branches will be updated if severe errors are found. For more detailed information about the "Ørsted" release please read the long release announcement on the Einstein Toolkit web pages: http://einsteintoolkit.org/about/releases/ET_2012_11_announcement.php.

upcoming release
by Frank Loeffler 08 Nov '12

08 Nov '12

Hello I would like to inquire about any left-over issues holding up the release. So far, only one ticket is still open, has an applied patch and only waits for test results: https://trac.einsteintoolkit.org/ticket/434. Is there anything else that somebody considers holding up the release? If I don't receive anything by about noon today we will release * today * Frank Löffler

meeting minutes
by Roland Haas 05 Nov '12

05 Nov '12

Present were: Frank, Roland, Bruno, Eloisa, Steve, Peter, Tanja, Ian, Yosef, Josh ET release: * Fank has created svn release branches, git branches will be created today * release notes are available at: https://docs.einsteintoolkit.org/et-docs/Release_Details both short and long would benefit from input * we will release independent of MHD paper status and create tags for the code version used in the paper once we have a version that works * we have two outstanding ticket tickets for the release: https://trac.einsteintoolkit.org/ticket/68 https://trac.einsteintoolkit.org/ticket/434 * ticket 68 concerns GetComponent hanging on subversion errors concerning invalid templates. A patch (actually two different ones) is provided but would need testing, ideally on machines where the error occurs. * ticket 434 concerns the excluded in Carpet's reduction mask - we had a lively discussion whether this is critical or can be ignored. Not final decision was reached. - two options are possible: -- leave as is and release with note about warning -- increase warning level/make dependent on verbosity parameter - the later requires that we understand that the error is benign - Roland will reproduce the error with trunk code and qc0-mclachlan in the release code. Will attach error and parfile to ticket. MHD paper: * will have phone call after the ET call Yours, Roland

Tests taking a long time
by Ian Hinder 01 Nov '12

01 Nov '12

Hi, For some reason, the automated tests are taking a very long time to run; more than the one hour wall time which I have given them. They used to run in under 10 minutes. Has something changed recently that could explain this, or should I look for problems on the cluster? -- Ian Hinder http://numrel.aei.mpg.de/people/hinder
