No Einstein Toolkit Meeting
by Frank Loeffler 29 Aug '14

29 Aug '14

Hi, There will be no Einstein Toolkit Meeting next Monday, as most of the people in the US will celebrate Labor day (doing the opposite). If you feel that something has to be discussed before the next meeting on Sep 8th, please use this email list. Frank Loeffler

Einstein Toolkit Meeting Minutes
by Frank Loeffler 29 Aug '14

29 Aug '14

Hi, I apologize for the late minutes. Present were (and I quite probably forgot someone): Peter, Erik, Zach, Philipp, and Frank > - 1648: MPI thorn should auto configure (new patch) This has in the meantime been committed. > - 1618: Compile with adaptive MPI (no new patch yet) This is still in the works. > - Make Illinois code work with standard ET There are still discrepancies between GRHydro+HLLE and other codes (Whisky, IllinoisGRMHD) and HLLE that are not understood. > - git transition Please test the new repositories. They are still checked out in /repos, but should work. Make sure you have (write) access if you think you should have. You will need a bitbucket account. > - MHD status & interest in vector potential There is currently only little attention and interest in this, with the slight hope of revival in about two months or so, according to Philipp. Frank

Migration from SVN to Git
by Barry Wardell 20 Aug '14

20 Aug '14

Hi, Following on from the discussion in the last Einstein Toolkit meeting, this is an update of the status of the transition from svn to git. * (Almost) all Cactus and Einstein Toolkit arrangements have now been converted to git and merged into a one-repository-per-arrangement layout. * The repositories are available on Bitbucket under the Cactus < https://bitbucket.org/cactuscode> and EinsteinToolkit < https://bitbucket.org/einsteintoolkit> team pages. * The git testing thornlist < http://svn.einsteintoolkit.org/manifest/trunk/git_testing.th> has been updated to point to the new repositories. I have verified that it is possible to checkout and build the Einstein Toolkit using this thornlist. * The conversion process is automated using scripts provided in the ET git transition repository <https://bitbucket.org/ianhinder/etgittransition>. * All master, ET release and Cactus release branches have been checked to perfectly match (i.e. no missing commits, no file differences) their svn counterparts. Similarly for the ET and Cactus release tags. * There is a list of known outstanding issues available < https://bitbucket.org/ianhinder/etgittransition/src/master/issues.md>. It's likely that most, if not all of these issues are sufficiently minor that they can be ignored. To proceed further it would be helpful if people (particularly those responsible for maintaining thorns and those who have opinions on how the final layout should appear) could take a look at the repositories and report any issues or suggested changes. In particular, it would be helpful to have feedback on how to handle AEIThorns, LSUThorns, ExternalLibraries, GRHydro, and the TAT thorns. Regards, Barry

Cactus build problems
by Ian Smith 20 Aug '14

20 Aug '14

Hi List! I've tried building this a few times over the last couple of years, on different machines, and always get stuck at the build stage, currently I have this set of errors: ------------------------------------------------------ There were 3 errors during execution of the CST These must be corrected before compilation can proceed ------------------------------------------------------ ------------------------------------------------------ Warnings were generated during execution of the CST ------------------------------------------------------ CST error 1: -> Configuration script for thorn FORTRAN returned exit code 1 Error message: 'Fortran thorn requires that a Fortran compiler is defined, but F77 = 'none' and F90 = 'none'. Aborting.' CST error 2: -> Configuration script for thorn LORENE returned exit code 1 (no error message) CST error 3: -> Configuration script for thorn MPI returned exit code 1 (no error message) ------------------------------------------------------ I have all the compilers that I think are needed, and have also added the dependencies listed at https://docs.einsteintoolkit.org/et-docs/Simplified_Tutorial_for_New_Users I have also tried things like: export F77=/usr/bin/f77 export F90=/usr/bin/f95 to no avail. As for installed packages, these seem relevant to the errors . . . ian@bonsai Tue Jul 29 02:58 PM /opt/EinsteinToolkit/Cactus $ aptitude search fort | grep '^i' i fort77 - Invoke f2c like a real compiler i gfortran - GNU Fortran 95 compiler i A gfortran-4.8 - GNU Fortran compiler i A libgfortran-4.8-dev - Runtime library for GNU Fortran applicatio i libgfortran3 - Runtime library for GNU Fortran applicatio ian@bonsai Tue Jul 29 02:58 PM /opt/EinsteinToolkit/Cactus $ aptitude search mpi | grep '^i' i libmpich-dev - Development files for MPICH i A libmpich10 - Shared libraries for MPICH i libmpich2-dev - Transitional dummy package for MPICH devel i A libopenmpi1.6 - high performance message passing library - i A mpi-default-bin - Standard MPI runtime programs (metapackage i A mpich - Implementation of the MPI Message Passing i mpich2 - Transitional dummy package i A openmpi-bin - high performance message passing library - i A openmpi-common - high performance message passing library - Can anyone assist with this?

In fact builds for the last month have been with the cnf file in the attachment named david.cfg. My only recent problem ( not related) is the number of nodes not working please take a look at the file and see if it helps any. Also, any additions appreciated. What is your thoughts on .cactus file in home account. Dave

Simfactory: Machine definition variables
by Dumsani Ndzinisa 09 Aug '14

09 Aug '14

Hi everyone, I am trying to configure and add a new machine (cluster) into my Simfactory machine database. (.../simfactory/mdb/machinses/). However, I do not know what exactly what the following variables or abbreviations are in the .ini file: spn, mpn. I have looked up values given to these in different machine files and found that they are not the same for all machines. Which brings me to the question of what they are so I can give to them the correct values relevant to/for the new machine that I want to add. I understand ppn represents the number *p*rocessors *p*er *n*ode or number of cores per node (SimfactoryAdvancedTutorial) <https://docs.einsteintoolkit.org/et-docs/Simulation_Factory_Advanced_Tutori…> . On this one, what exactly should determine the value for *min-ppn* as far as the machine being defined is concerned? Or the min-ppn's value doesn't depend on the machine? Thank you in advance fr your help. Dumsani
