This repository currently contains the workflow we have used for running 2x2 detector simulation productions at Argonne National Laboratory on ALCF Polaris Machine.
It would be helpful to get familiar with the Balsam software https://balsam.readthedocs.io/en/latest/ to understand the workflow scripts, and ALCF Docs for job submission.
Before using these scripts, you would need to create your own Balsam site (due to settings that are user specific or machine specific that are required to run and submit jobs) and place these folders inside of it. Creating a Balsam site: https://balsam.readthedocs.io/en/latest/tutorials/theta-quickstart/#create-a-balsam-site
In the directory Balsam/2x2_production_polaris you will find the following folders:
data: Contains the source code for 2x2_sim simulation linked to the repository maintained by 2x2 collaboration (https://github.com/DUNE/2x2_sim). The latest tutorial to understand the software is at https://github.com/DUNE/2x2_sim/wiki/Tutorial-on-running-2x2_sim-Apr2024 and will be updated as when the software does.scripts/apps: These scripts create the "apps" (Each app defines a job flow that you would like to run, for eg. if you want to setup jobs for the edep sim stage of 2x2, you define the specific environment variables for that stage and edep sim script to run).scripts/workflows: These scripts create jobs based out of the apps. For every job, we set the indices for the jobs, add unique tags so that it can be queried and specify dependent jobs. These scripts also submit these jobs to run to the ALCF Polaris Machine.scripts/utils: Some helpful Balsam files for modifying created jobs.specs: Environment variables required for each production is stored as yaml files and are loaded by the app creation scripts.admin: contains common scripts for fetching singlarity containers as required, transferring files across facilities and generation of metadata.usage_summary: Reports on production runs.
