Notable Batch Scheduling and Execution Environments
UNIX utilizes cron and at facilities to allow for scheduling of complex job scripts. Windows has a job scheduler. Most high-performance computing clusters use batch processing to maximize cluster usage.
The IBM mainframe z/OS operating system / platform has arguably the most highly refined and evolved set of batch processing facilities owing to its origins, long history, and continuing evolution, and today such systems commonly support hundreds or even thousands of concurrent online and batch tasks within a single operating system image. Mainframe-unique technologies that aid concurrent batch and online processing include Job Control Language (JCL), scripting languages such as REXX, Job Entry Subsystem (JES2 and JES3), Workload Manager (WLM), Automatic Restart Manager (ARM), Resource Recovery Services (RRS), DB2 data sharing, Parallel Sysplex, unique performance optimizations such as HiperDispatch, I/O channel architecture, and several others.

Famous quotes containing the words notable, batch, execution and/or environments:
“a notable prince that was called King John;
And he ruled England with main and with might,
For he did great wrong, and maintained little right.”
—Unknown. King John and the Abbot of Canterbury (l. 2–4)
“Do you not know that a little yeast leavens the whole batch of dough?”
—Bible: New Testament, 1 Corinthians 5:6.
“Some hours seem not to be occasion for any deed, but for resolves to draw breath in. We do not directly go about the execution of the purpose that thrills us, but shut our doors behind us and ramble with prepared mind, as if the half were already done. Our resolution is taking root or hold on the earth then, as seeds first send a shoot downward which is fed by their own albumen, ere they send one upward to the light.”
—Henry David Thoreau (1817–1862)
“Corporate America will likely be motivated to support child care when it can be shown to have positive effects on that which management is concerned about—recruitment, retention and productivity. Indeed, employers relate to child care as a way to provide growth fostering environments for young managers.”
—Dana E. Friedman (20th century)
