Set execution hints at task level


Apart from being able to control Seven Bridges [execution hints](doc:list-of-execution-hints) at [workflow level](doc:set-execution-hints-at-workflow-level), the CGC also allows you to set instance type and the maximum number of instances that can run in parallel for each individual task run. Specifically, the following hints `sbg:AWSInstanceType`, `sbg:GoogleInstanceType` and `sbg:maxNumberOfParallelInstances` can also be set at task level. Values set for an individual task will override the values set at workflow level, according to the following priority: **task** > **workflow** >**node**. ## Via the visual interface Instance type hint and level of parallelization can be activated on draft task page following the procedure below: 1. [Create a draft task](doc:run-a-task#section-create-draft-task). 2. On the draft task page, select the **Execution Settings** tab. 3. In the **Instance type** section, select **Custom**. Instance selection options are displayed. 4. In the **Instance** dropdown select the instance you want to use for task execution. You can also add or change the value in the [Attached Storage](doc:set-computation-instances#section-set-attached-storage-size) field to define the size of storage attached to the computation instance. 5. Set the maximum number of parallel instances for **Parallelization**. This defines the maximum number of instances that can run in parallel for app execution. You have now configured execution hints for the given task. ## Via the API To set task level hints via the API, you have `instance_type` and `max_parallel_instances` parameters in `execution_settings` as part of the following API calls:  * [Create a new draft task](doc:create-a-new-task) * [Modify a task](doc:modify-a-task) * [Get details of a task](doc:get-details-of-a-task)
