h1. Common Workflow Language integration with Arvados The main integration is @arvados-cwl-runner@. This tool is can be used both to either run the workflow directly (@arvados-cwl-runner --local@) or as a client to submit which submits a job to run the workflow (@arvados-cwl-runner --submit@) and for running the workflow directly (@arvados-cwl-runner --local@). --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. !cwl-arvados-flow-local.png! !cwl-arvados-flow-submit.png!
