Chronos is a scheduling application that enables job orchestration on Mesos operating systems. The program, which is fault tolerant, runs primarily via a main loop that begins with a reading of all job statuses. Following the first step, Chronos registers jobs for tracking and then separates them depending on when they are scheduled to be run. All jobs are then queued in a list and run when sufficient resources are available. Additional detail on the Chronos application can be found at
