Compiling and running on Perlmutter

• Create ET folder in the home directory:

  cd ~/
  mkdir ET
  cd ET
  

• Download the code via the following commands:

  curl -kLO https://raw.githubusercontent.com/gridaphobe/CRL/master/GetComponents
  chmod a+x GetComponents
  ./GetComponents --root Cactus --parallel --no-shallow https://raw.githubusercontent.com/jaykalinani/AsterX/main/Docs/thornlist/asterx.th
  

• Add a defs.local.ini file in Cactus/simfactory/etc/., with details on user account details, source and base directory paths. See, for example: https://github.com/jaykalinani/AsterX/blob/main/Docs/compile-notes/frontier/defs.local.ini

• Return to Cactus directory and compile using the following command:

  ./simfactory/bin/sim build -j32 <config_name> --thornlist=./thornlists/asterx.th --machine=perlmutter-p1
  

• Example command to create-submit a job for a shocktube test via simfactory

  ./simfactory/bin/sim submit B1 --parfile=./arrangements/AsterX/AsterX/test/Balsara1_shocktube.par --config=<config_name> --machine=perlmutter-p1 --allocation=m3374 --procs=1 --num-threads=1 --ppn-used=1 --walltime 00:01:00
  

• For a magnetized TOV test evolving spacetime, example submit command via simfactory

  ./simfactory/bin/sim submit magTOV_unigrid --parfile=./arrangements/AsterX/AsterX/par/magTOV_unigrid.par --config=<config_name> --machine=perlmutter-p1 --allocation=m3374 --procs=4 --num-threads=1 --ppn-used=4 --walltime 00:03:00
