Concurrency parameter question

[Sederfo]

What does concurrency actually mean? Suppose I have an event that runs every 5 minutes. If the event has concurrency 1 (singleton) does that mean that if the previous job from 5 minutes ago is taking a bit longer and is still running, a new job will not be started? As in, it will omit starting it until the previous job is completed?

I have found my answer shortly thereafter in the docs. I should have looked better :) I am closing this question now.

Event Concurrency
The Event Concurrency selector allows you to specify how many simultaneous jobs are allowed to run for the event. For example, multiple jobs may need to run if your event is scheduled to run hourly, but it takes longer than a hour to complete a job. Or, a job may be already running and someone clicks the "Run Now" link on the Schedule tab. This selector specifies the maximum allowed jobs to run concurrently for each event.

If an event cannot start a job due to the concurrency limit, an error is logged (see the Activity Log Tab below). What happens next depends on the Event Options. If the event has Run All (Catch-Up) mode enabled, then the scheduler will keep trying to run every scheduled job indefinitely. Otherwise, it will simply wait until the next scheduled run.
