The Windows Task Manager is a powerful tool that displays information about the processes and applications that are currently running on your computer. The Task Manager also includes a feature called the CPU Scheduler, which is used to manage the use of the CPU by different applications.
You might be wondering about CPU Scheduling: What it is and its role? Well, the CPU scheduler is a component of the operating system that determines how and when individual tasks running on the system will be executed. The scheduler assigns a "time slice" to each task, which is the amount of time that task will be allowed to run before it is interrupted by another task. The scheduler then moves through the list of tasks, executing one task for each elapsed time slice.
When you first start your computer, the Windows Task Manager displays only a few processes running on your computer under the Processes tab. But as you open applications, such as MS Word or Internet Explorer, the list of processes displayed by Windows Task Manager also increases to accommodate these new processes. This is because many programs running together are referred to as a job, and each of these programs must have access to resources provided by the operating system itself. To accomplish this task, modern computers have multi-core CPUs with several processor cores, which can run multiple jobs at once, allowing for faster program execution.
You can see in action by opening up Windows Task Manager and looking at the column labelled CPU. As you can see in the following illustration, different applications are consuming different amounts of the available CPU time.
The Windows Task Manager can be used to view and manage the use of the CPU by different applications. The following are some tips on how to use the Windows Task Manager to manage the CPU:
Within any given operating system, many jobs or processes are constantly running. Each of these jobs or processes must be assigned a priority, which specifies how important the task is to the computer system. The scheduler, which manages the CPU time of each process, uses this priority to determine how much CPU time each job will get while it is running on the computer.
For example, if your computer were only using 20% of its available CPU capacity for some reason (maybe another application was consuming 80%), then if you were running an audio editing program that had received a low priority from Windows Task Manager, there wouldn't really be an incentive for Windows to give up any more of its available processing power than necessary in order to run your audio editing program faster than it would otherwise run on its own.
However, as per our Australian information technology assignment help mentors, if you were running a resource-intensive application such as an image rendering program or a video encoding program that had been assigned a high priority, there would be more incentive for Windows to give up some of its available processing power so it could run these applications faster. In this case, Windows might even temporarily suspend other processes in order to free up the necessary resources required by the high priority process to run at full speed.
When it comes to GPU overclocking and undervolting, CPU priority becomes important because each application – including each graphics card driver – runs with its own processor affinity set. This means that each individual graphics card driver has its own list of instructions that tells the scheduler which CPU to run it on.
For example, if you have a Radeon HD 6970 graphics card installed in your computer and you were using ATI Stream to encode video using the GPU, the scheduler would always see this process as running on CPU 0. This is even true if you had another high-priority process consuming all of the resources available on CPU 0. All processes, including graphics card drivers, will always run on whatever CPU number they are associated with within the operating system.
These tweaks will help maintain good CPU scheduling and can help improve overall system performance. Processor scheduling is an important factor to consider when trying to optimise your system for gaming or other high-demand activities. It would help if you experimented with the different options to see which work best for you. Some of these settings can be changed on the fly, so you can quickly adjust them if needed.
