A job scheduler is a computer application for controlling unattended background program execution of jobs. [1] This is commonly called batch scheduling, as execution of non-interactive jobs is often called batch processing, though traditional job and batch are distinguished and contrasted; see that page for details.
A batch window is "a period of less-intensive online activity", [11] when the computer system is able to run batch jobs without interference from, or with, interactive online systems. A bank's end-of-day (EOD) jobs require the concept of cutover , where transaction and data are cut off for a particular day's batch activity ("deposits after 3 PM ...
Batch production scheduling is the practice of planning and scheduling of batch manufacturing processes. Although scheduling may apply to traditionally continuous processes such as refining, [ 1 ] [ 2 ] it is especially important for batch processes such as those for pharmaceutical active ingredients, biotechnology processes and many specialty ...
The scheduler is an operating system module that selects the next jobs to be admitted into the system and the next process to run. Operating systems may feature up to three distinct scheduler types: a long-term scheduler (also known as an admission scheduler or high-level scheduler), a mid-term or medium-term scheduler, and a short-term scheduler.
It has since evolved into a sophisticated batch scheduler capable of satisfying the requirements of many large computer centers. As of November 2021 [update] , TOP500 list of most powerful computers in the world indicates that Slurm is the workload manager on more than half of the top ten systems.
Portable Batch System (or simply PBS) is the name of computer software that performs job scheduling. Its primary task is to allocate computational tasks, i.e., batch jobs, among the available computing resources. It is often used in conjunction with UNIX cluster environments.
In system software, a job queue (a.k.a. batch queue, input queue), is a data structure maintained by job scheduler software containing jobs to run. [1] Users submit their programs that they want executed, "jobs", to the queue for batch processing. The scheduler software maintains the queue as the pool of jobs available for it to run.
As the Honeywell Bull marketplace has eroded over the last twenty years, so PTC has expanded its product set to support many operating systems including Unix, Windows and VAX, whilst remaining firmly rooted to the original areas of expertise in Systems Management. The latest Scheduling tool, PTC Scheduler, is the fourth-generation product and ...
