Additional Information¶
Important Directories¶
/ligo/home/ligo.org/albert.einstein
: for normal user files, analysis output, etc./ligo/software/ligo.org/albert.einstein
: for software builds/cvmfs
: CVMFS data files served from a local NFS Aliencache and remote Stashcaches
Building Software¶
When compiling software, use the /ligo/software/
directory instead of the /ligo/home/
directory.
Conda Environments
By default, user conda environments are stored in /ligo/home/
, so this must be changed via:
ENV_DIR='conda-envs' # this is the folder name where you want to keep your environments
mkdir -p /ligo/software/ligo.org/${USER}/${ENV_DIR}
conda config --add envs_dirs /ligo/software/ligo.org/${USER}/${ENV_DIR}
Use conda activate
to load environments as usual. Verify your setup with conda info --env
; output should be similar to this:
$ conda info --env
# conda environments:
#
test-env * /ligo/software/ligo.org/albert.einstein/<conda-envs>/envs/test-env
To shorten the long path that prefixes the terminal prompt, enter:
conda config --set env_prompt '({name})'
After building software or moving environments to the /ligo/software
directory, reference that path in your HTCondor submit and DAG files in place of your /ligo/home
directory.
