describe()¶

determine()¶

filter_jobs(**kwargs) → List[schrodinger.application.desmond.cmj.Job]¶: Return a list of jobs based on a matching a set of criteria given as arguments. Read JobManager.filter_jobs for available arguments.

push(job)¶

release(is_restarting=False)¶: Calls the ‘crunch’ method to generate new jobs objects and submits them to the ‘QUEUE’.
