Inhomogeneous Cosmologies 2017 hands-on sessions

workshop notes - ET

http://einsteintoolkit.org
Participants to the ET tutorials are asked to install the toolkit and reproduce a simple spacetime prior to the workshop, following the instructions at https://docs.einsteintoolkit.org/et-docs/Simplified_Tutorial_for_New_Users.

Edit einsteintoolkit.th in your top ET directory with an editor
Find eloisa/ctthorns.git
A few lines later: !REPO_BRANCH = $ET_RELEASE should become !REPO_BRANCH = master
Add a few lines later: CTThorns/CT_Dust
You may safely comment out with "#" or remove the line Llama/WaveExtractL since it is heavy (RAM/cpu time) to compile and not needed.
You may safely comment out EinsteinInitialData/NoExcision
Now do: ./GetComponents einsteintoolkit.th
cd Cactus
Compile again: ./simfactory/bin/sim build --mdbkey make 'make -j2' --thornlist=manifest/einsteintoolkit.th
Run: ./simfactory/bin/sim submit eds-0001 --parfile=repos/ctthorns/par/eds.par --procs=1 --walltime=0:30:0

avoid filling home directory: To avoid creating a huge (733 Mb) directory in your home directory for the simplified tutorial for new users, create your target directory and soft link it to ~/simulations either before you start or before you start running a simulation.

~~We must recommend that participants try installing the packages and libraries before the session!~~ Done.

TODO: the default cosmo.nml.EdSbg file should be for 32^3, and there should be a warning to the user to check memory with free before starting the run!
