h1. Common Workflow Language integration with Arvados
The main integration is @arvados-cwl-runner@. This tool can be used to either run the workflow directly (@arvados-cwl-runner --local@) or as a client which submits a job to run the workflow (@arvados-cwl-runner --submit@). When the user starts a CWL workflow from workbench, it functions similar to @--submit@ mode.
Because submit mode works by creating a "runner" job whose purpose is to manage execution of the workflow, it requires an @arvados/jobs@ Docker image with an up-to-date @arvados-cwl-runner@.
When running a workflow, the workflow runner:
# creates a job for each workflow steps
# submits it
# waits for it to complete
# gets the output collection for the job
# computes the CWL output object for the workflow step.
