What does "Global Scheduler" mean?

Table of Contents

A global scheduler is a system that helps manage tasks across multiple working units, ensuring that they run smoothly and efficiently. In a setup where different requests are being handled, the global scheduler coordinates how these requests are processed to make the best use of available resources.

It looks at all the incoming tasks and determines the best way to organize them. This organization helps reduce waiting times and allows for shared resources, meaning that similar tasks can reuse previous results instead of starting from scratch.

By using a global scheduler, the overall performance of the system improves, with faster completion times for tasks and better use of memory. This system is especially useful when multiple requests have overlapping needs, allowing the system to work smarter and quicker.
