We describe an open job management architecture of the Blue Gene/L supercomputer. The architecture allows integration of virtually any job management system with Blue Gene/L with minimal effort. The architecture has several ”openness” characteristics. First, any job management system runs outside the Blue Gene/L core (i.e. no part of the job management system runs on Blue Gene/L resources). Second, the logic of the scheduling cycle (i.e. when to match jobs with resources) can be retained without modifications. Third, job management systems can use different scheduling and resources allocation models and algorithms. We describe the architecture, its main components, and its operation. We discuss in detail two job management systems, one based on LoadLeveler, the other — on SLURM, that have been successfully integrated with Blue Gene/L, independently of each other. Even though the two systems are very different, Blue Gene/L's open job management architecture naturally accommodated both.
