Cache warming?

The cache warmer is activated when content is changed. When you update a post, for example, it’s cache will be deleted, along with any associated category archives, comments, etc. If warming is enabled, instead of waiting for a visitor to hit the page and rebuild the cache, it will ping the pages in the background and rebuild the cache automatically.

If you’re looking to actively rebuild the entire cache or something like that, this can be done, but this is not a part of the plugin. Typically you’d want to set up a php script on a cron job to accomplish this. If you’re interested, I can supply examples of code you’d use to interact with the cache in order to rebuild pages.
