104 h3(#nowait). Submit a workflow without waiting for the result
106 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.

118 h3(#local). Control a workflow locally
120 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 containers, however, the containers themselves will still run on the Arvados cluster. With @--local@, if you interrupt @arvados-cwl-runner@ or log out, the workflow will be terminated.

141 h3(#delete). Automatically delete intermediate outputs
143 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.
145 Temporary collections will be trashed @intermediate-output-ttl@ seconds after creation. A value of zero (default) means intermediate output should be retained indefinitely.
147 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.
149 Using @--trash-intermediate@ without @--intermediate-output-ttl@ means that intermediate files will be trashed on successful completion, but will remain on workflow failure.
151 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).
153 h3(#federation). Run workflow on a remote federated cluster
155 By default, the workflow runner will run on the local (home) cluster. Using @--submit-runner-cluster@ you can specify that the runner should be submitted to a remote federated cluster. When doing this, @--project-uuid@ should specify a project on that cluster. Steps making up the workflow will be submitted to the remote federated cluster by default, but the behavior of @arv:ClusterTarget@ is unchanged. Note: when using this option, any resources that need to be uploaded in order to run the workflow (such as files or Docker images) will be uploaded to the local (home) cluster, and streamed to the federated cluster on demand.
157 h3(#preemptible). Using preemptible (spot) instances
159 Preemptible instances typically offer lower cost computation with a tradeoff of lower service guarantees. If a compute node is preempted, Arvados will restart the computation on a new instance.
161 If the sitewide configuration @Containers.AlwaysUsePreemptibleInstances@ is true, workflow steps will always select preemptible instances, regardless of user option.
163 If @Containers.AlwaysUsePreemptibleInstances@ is false, you can request preemptible instances for a specific run with the @arvados-cwl-runner --enable-preemptible@ option.
165 Within the workflow, you can control whether individual steps should be preemptible with the "arv:UsePreemptible":cwl-extensions.html#UsePreemptible hint.
167 If a workflow requests preemptible instances with "arv:UsePreemptible":cwl-extensions.html#UsePreemptible , but you _do not_ want to use preemptible instances, you can override it for a specific run with the @arvados-cwl-runner --disable-preemptible@ option.
169 h3(#gpu). Use CUDA GPU instances
171 See "cwltool:CUDARequirement":cwl-extensions.html#CUDARequirement .
