h3. Submit a workflow with no waiting
To submit a workflow and exit immediately, use the @--no-wait@ option. This will submit the workflow to Arvados, print out the UUID of the job that was submitted to standard output, and exit.

h3. Control a workflow locally
To run a workflow with local control, use @--local@. This means that the host where you run @arvados-cwl-runner@ will be responsible for submitting jobs, however, the jobs themselves will still run on the Arvados cluster. With @--local@, if you interrupt @arvados-cwl-runner@ or log out, the workflow will be terminated.

}
h3. Automatically delete intermediate outputs
Use the @--intermediate-output-ttl@ and @--trash-intermediate@ options to specify how long intermediate outputs should be kept (in seconds) and whether to trash them immediately upon successful workflow completion.
Temporary collections will be trashed @intermediate-output-ttl@ seconds after creation. A value of zero (default) means intermediate output should be retained indefinitely.
Note: arvados-cwl-runner currently does not take workflow dependencies into account when setting the TTL on an intermediate output collection. If the TTL is too short, it is possible for a collection to be trashed before downstream steps that consume it are started. The recommended minimum value for TTL is the expected duration for the entire the workflow.
Using @--trash-intermediate@ without @--intermediate-output-ttl@ means that intermediate files will be trashed on successful completion, but will remain on workflow failure.
Using @--intermediate-output-ttl@ without @--trash-intermediate@ means that intermediate files will be trashed only after the TTL expires (regardless of workflow success or failure).
