Pilot job

In computer science, a pilot job is a type of multilevel scheduling, in which a resource is acquired by an application so that the application can schedule work into that resource directly, rather than going through a local job scheduler, which might lead to queue waits for each work unit. This term comes from the Condor High-Throughput Computing System, in which Condor GlideIns[1] provides this functionality. Other examples of pilot jobs are: the BigJob implemented in SAGA,[2] Swift Coasters as part of the Swift[3] parallel scripting system, the Falkon[4] lightweight task execution framework, and HTCaaS.[5]

Pilot jobs are most often used on systems that have queues, as part of their purpose is, in some sense, to avoid multiple waits in these queues. These are most often found in parallel computing systems, but pilot jobs are usually part of a distributed application, and are many times associated with Many-task computing.
