Job scheduler
open-in-new
<p>A job scheduler is a computer application for controlling unattended background program execution of <a href="/facts/Job_(computing)/pW4LEz0Q">jobs</a>. This is commonly called batch scheduling, as execution of non-interactive jobs is often called <a href="/facts/Batch_processing/hKY2rX3N">batch processing</a>, though traditional <i>job</i> and <i>batch</i> are distinguished and contrasted; see that page for details. Other synonyms include batch system, distributed resource management system (DRMS), distributed resource manager (DRM), and, commonly today, workload automation (WLA). The data structure of jobs to run is known as the <a href="/facts/Job_queue/Rx5mB5Pw">job queue</a>. </p><p>Modern job schedulers typically provide a graphical user interface and a <a href="/facts/Device_management/Br61Lw6b">single point of control</a> for definition and monitoring of background executions in a distributed network of computers. Increasingly, job schedulers are required to orchestrate the integration of real-time business activities with traditional background IT processing across different <a href="/facts/Operating_system/8XTuvMh2">operating system</a> platforms and business application environments. </p><p><i>Job scheduling</i> should not be confused with <a href="/facts/Scheduling_(computing)/XptmcM1a">process scheduling</a>, which is the assignment of currently running processes to <a href="/facts/CPU/Jxp1bqMV">CPUs</a> by the <a href="/facts/Operating_system/8XTuvMh2">operating system</a>. </p>
