Running a Task in Parallel
You can run tasks in parallel within a job. Each task you select to run in parallel will run at the same time. For example, if a job has 3 tasks, you may want to execute steps 1 and 2 in parallel. You can enable these two tasks to run in parallel and when this job is run, these tasks will run at the same time while any remaining tasks will run sequentially.
To run a task in parallel, in your sequenced tasks list click on the Parallel toggle action on the right of a task.
In the following image, I have chosen two tasks to run in parallel. During the next execution of this job, these tasks will run in parallel and not sequentially.
To run tasks in parallel, the tasks must be sequenced beside each other.
For example, task 1 and task 2 can run in parallel, but task 4 cannot run in parallel with task 1 if its preceding tasks (task 2 and task 3) are not also run in parallel.
In the following image, the selected tasks will not run in parallel as they are not sequenced beside each other.
Please note that a task that has a dependency on another task cannot run in parallel with that task. Tasks that have been selected to run in parallel also cannot have a dependency on each other. If a task is dependent on a parallel task, the dependent task will run after all parallel tasks have completed.
