comps-sif-constructor 0.2.0

Create a SIF file from a Singularity definition file for COMPS

comps-sif-constructor

Create SIF images for COMPS

To use (with uv):

uvx comps_sif_constructor create -d lolcow.def

This will launch the image creation on COMPS and leave behind a sif.id for the jobs that need the image.

                                   --file FILE [--sif-filename SIF_FILENAME]
                                   [--sif-id-file SIF_ID_FILE]

options:
  --help                show this help message and exit
  --name NAME, -n NAME  Name of the experiment
  --threads THREADS, -t THREADS
                        Number of threads to use
  --priority PRIORITY, -p PRIORITY
                        Priority level for the experiment
  --node-group NODE_GROUP, -g NODE_GROUP
                        Node group to use
  --file FILE, -f FILE  Path to the trials.jsonl file
  --sif-filename SIF_FILENAME, -s SIF_FILENAME
                        Name of the singularity image file
  --sif-id-file SIF_ID_FILE, -i SIF_ID_FILE
                        Path to the asset ID file

Example:

comps_sif_constructor launch \
  -n "My Experiment" \
  -t 4 \
  -p AboveNormal \
  -g idm_48cores \
  -f trials.jsonl \
  -s custom_image.sif \
  -i custom_image.id
