Problem with compiling Einstein Toolkit on Cray system
by L.S. Oswald 16 Sep '16

16 Sep '16

Hello I'm attempting to install the Einstein Toolkit on Dora, which is a Cray system supercomputer. In doing so I came across the following error: Configuration script for thorn MPI returned exit code 5 Error message: 'MPI could not be configured: neither automatic nor manual configuration succeeded' In addition the log stated that: No MPI compiler wrapper found beneath MPI_DIR (MPI_DIR = /usr) I subsequently discovered that it was looking in the wrong place for the MPI root directory and that the reason it was looking under /usr instead of /opt/cray/mpt/7.3.2/gni/mpich-cray/8.3 was because that was the setting in the ubuntu configuration file that I had used when configuring SimFactory. On a reattempt therefore I did not use the ubuntu.cfg file when configuring SimFactory, and got the following error instead: Configuring with flesh MPI Warning: use of flesh MPI via MPI option is deprecated and should be replaced with the thorn ExternalLibraries/MPI and its MPI_DIR option MPI selected, but no known MPI method - what is "/opt/cray/mpt/7.3.2/gni/mpich-cray/8.3" ? Attempts at altering the Makefile and the config-info file resulted in either no change, or more errors. Please would you be able to advise me on the correct way to specify the root directory for MPI? Many thanks, Lucy Oswald

Checkpointing with Cactus/Simfactory
by dumsani 31 Aug '16

31 Aug '16

Hi All, I have some very long BH simulations to run and I'd like to checkpoint for these. I haven't really done checkpointing before. But what I know is that chekpointing information can be specified in the parameter file (for use by Cactus), and also that Simfactory does seem to have some stuff to do with or handle checkointing ( "restart-id", etc...). Of course, scheduling systems (e.g. PBSPro) at HPCs would have support for checkpointing but I don't want to use that. Probably it is only best to use that to set the walltime. So, my main question is: Assuming I set a maximum walltime of 12 hours, and I set my simulation to dump checkpoints every 3hrs (in walltime units), how do I *restart* my job at the end of the 12 hrs using Simfactory in a way that the simulation starts off from the last checkpoint it droppped before terminating? What extra command line options should I pass to the sumbit command of SImfactory? Below is a segment of my parfile where checkpointing information is given, provides as a sample or as a basis for anyone who would want to advise me on how such information should be given. ##### Checkpointing ######### CarpetIOHDF5::checkpoint = yes IO::checkpoint_ID = yes IO::recover = autoprobe IO::checkpoint_every = 1024 IO::out_proc_every = 2 IO::checkpoint_keep = 3 IO::checkpoint_dir = $parfile Carpet::regrid_during_recovery = no CarpetIOHDF5::use_grid_structure_from_checkpoint = yes CarpetIOHDF5::open_one_input_file_at_a_time = yes Your advice and assistance will be highly appreciated. Best, Dumsani

Present: Frank, Roland, Zach, Matt, Erik, Roberto di Pietro, * close ticket on floating release branch since it seems not straightforward to * Frank and Steve went through the piraha-everywhere branch and now are only minor issues left. It will most likely arrive on master soon. This will cause a force-rebuild to regenerate the ccl generated files * restart developer workshops (twice a year). Most likely focused on particular topics so that not everyone (needs to) attend. * monthly task-based remote developer's day so that there is minimum amount of progress on these topics. Initially try using google hangout for this. * please suggest topics that would require 3-4 hours of developer work ** update of the webpage to simplify navigation, a suggestion is to use bootstrap http://v4-alpha.getbootstrap.com/examples/ which uses javascript/css to ensure proper layout on desktops/phones/tablets. Uses javascript for menus, common include headers. Erik played around with http://jekyllrb.com which generates mostly static HTML pages from some markdown type source. ** make sure all example parfiles scattered throughout the ET work ** minor coding projects like writing a single HDF5 file of output rhather than 1 per variable or 1 per group Yours, Roland -- My email is as private as my paper mail.

Present: Erik, Steve, Roland, Frank, Peter, Ian Formaline: * Formaline seems very slow, we suspect this to be due to either larger files being added to tarballs and/or Roland's change that circumvents gits internal caching * suggested solutions include undoing the commit and trying to work around file systems that do not support hard links as well as tighter integration of Formaline with the flesh make targets to start Formaline's processing early * Formaline misses adding Makefile to the tarball, a workaround is to tar up the flesh repo directly by first de-referencing Makefile (if it is a symbolic link), then including the directory containing that file in the tarball. This should work for common situations Having a moving release branch: * Roland had suggested having a moving release branch so that eg websites could refer to that branch rather than having to be updated after each release, the hope is also to offer a simpler update path than "wipe your old Cactus tree and download a new one" * a suggestion is to only have such a branch in the manifest repo and nowhere else * Ian dislikes the idea of a moving branch since he fears it will interact badly with git pull * Erik points out that git pull will report conflicts if the release branch jumps from one release to the next and suggests to use a tag instead, Roland thinks this will not happen and will test this with locally and report back * having a simpler way to point to the current release is agreed to be nice but no simple way to achieve this seems obvious -- My email is as private as my paper mail.

Re: [Users] [Einstein Toolkit] #1938: trouble installing readline
by David Rosenberg 08 Aug '16

08 Aug '16

After searching the dozens of web sites with this problem, I found a solution: readline-devel, ncurses-devel, lua-binary which I loaded and got around the problem. It almost compiled but had problems with fortran compiler complaining about cray pointers. Will be in touch if I can;t solve this one THANK YOU!
