Open Source Job Scheduler was created in 2005.
What is job scheduler and dispatcher?
No. The Job Scheduler is the high-level scheduler.
1. Job scheduler is also called long term scheduler and CPU scheduler is called short term scheduler. 2. Job scheduler selects the processes from the job pool and load them in to the memory for execution. in other hand CPU scheduler selects among the processes that are in ready to execute and allocate the CPU to one of them. 3. CPU scheduler is faster than the process scheduler.
long-term scheduler...
Jobs or processes are the same. Whereas, Job scheduler and CPU scheduler are two different terms. Job scheduler is also called long term scheduler and CPU scheduler is called short term scheduler. While Job scheduler selects the processes from the job pool (Job pool is on the Hard disk) and load them in to the memory (Main Memory or RAM) for execution. in other hand CPU scheduler selects among the processes (in RAM) that are ready for execution and allocates the CPU to one of them. Hope I got it right and answered your query. Sorry for any mistakes as I'm not perfect as well. :) Cheers, KV

The long-term scheduler, also known as the job scheduler, is responsible for selecting processes from the job pool and loading them into memory for execution, determining the degree of multiprogramming. In contrast, the short-term scheduler, or CPU scheduler, selects which of the ready processes in memory should be executed by the CPU next, making decisions on a much shorter timescale, typically in milliseconds. While the long-term scheduler controls the overall balance of the system, the short-term scheduler focuses on optimizing CPU utilization and responsiveness.
A job scheduler is a software programme that is used for controlling and timing, as well as planning of the background execution of programs. It is used for the automation of programs, scripts and database procedures.

A job scheduler is a computer program used for controlling background program execution. It is used for programs that that need to run at regular intervals without the need for human intervention.
There are many providers of job scheduling software. Halcyon Software make the Advanced Job Scheduler that one can downloaded from their official website.
A batch queue is a system software data structure maintained by job scheduler software.
