Interface to GPU-enabled python library for generating extragalactic mock skies.
- git clone https://github.com/exgalsky/mockgen.git
- cd mockgen
- pip install .
Currently runs on perlmutter in the xgsmenv enviroment.
Mocks can be generated through the command line interface:
# on Perlmutter at NERSC with one GPU node:
% module use /global/cfs/cdirs/mp107/exgal/env/xgsmenv/20231013-0.0.0/modulefiles/
% module load xgsmenv
% salloc -N 1 -C gpu
% export XGSMENV_NGPUS=4
% srun -n 4 mockgen mockgen-test
