#2174: Test "Multi Patch Scalar Wave Equation" example
Reporter:Roland Haas
Status:open
Milestone:ET_2023_11
Version:development version
Type:task
Priority:major
Component:EinsteinToolkit website

Changes (by Roland Haas):

Before each release, check that http://einsteintoolkit.org/gallery/multipatch/index.html still works and produces correct output.

Steps:

1. download the development version of the Einstein Toolkit:

curl -kLO https://raw.githubusercontent.com/gridaphobe/CRL/master/GetComponents
chmod a+x GetComponents
./GetComponents https://bitbucket.org/einsteintoolkit/manifest/raw/master/einsteintoolkit.th

2. download the parameter file fro the gallery example

cd Cactus
wget --output-document par/Kerr-Schild_Multipole.par https://bitbucket.org/llamacode/llama/raw/master/LlamaWaveToy/par/Kerr-Schild_Multipole.par

3. compile Cactus for the system you are on (this may require that you add a cluster allocation etc.)

./utils/Scripts/MakeThornList --master thonrlists/einsteintoolkit.th --output thornlists/Kerr-Schild_Multipole.th
./simfactory/bin/sim setup-silent
./simfactory/bin/sim build --thornlist thornlists/Kerr-Schild_Multipole.th

4. run the simulation, using number of MPI ranks similar to what is shown on the ET website, so for example

./simfactory/bin/sim create-submit --parfile par/Kerr-Schild_Multipole.par --cores 8  --num-threads 2 --walltime 0:30:00

5. on your laptop install VisIt using the precompiled executable available from its download page
6. get the VisIt session file

wget http://einsteintoolkit.org/
