maxSubmitAwait

The maxSubmitAwait directive defines how long a task can remain in submission queue without being executed. Tasks that exceed this duration in the queue will fail.

It can be used with the retry error strategy to re-submit tasks to a different queue or with different resource requirements. For example:

process hello {
    errorStrategy 'retry'
    maxSubmitAwait 10.m
    maxRetries 3
    queue "${task.submitAttempt==1 ? 'spot-compute' : 'on-demand-compute'}"

    script:
    """
    your_command --here
    """
}

In the above example, each task is submitted to the spot-compute queue on the first attempt (task.submitAttempt==1). If a task remains in the queue for more than 10 minutes, it fails and is re-submitted to the on-demand-compute queue.
