CPU schedulingis the process of deciding which process will own the CPU to use while another process is suspended. The main function of the CPU scheduling is to ensure that whenever the CPU remains idle, the OS has at least selected one of the processes available in the ready-to-use line....
Developing CPU scheduling algorithms in operating system and understanding effect of various algorithms in practice can be difficult and deadly because of the requirement to update the operating system and test operating system kernel code and quantity the succeeding presentation of operating system on a...
In general CPU utilization and Throughput are maximized and other factors are reduced for proper optimization. Scheduling Algorithms To decide which process to execute first and which process to execute last to achieve maximum CPU utilization, computer scientists have defined some algorithms, they are:...

The workload on the OS (that is, the running status of various tasks) is always ever-changing. In order to better understand the principles of various CPU scheduling algorithms, we first make the following assumptions on the workload:
which enables hardware-software collaboration to scale down power and performance of hardware whenever the system performance can be relaxed, is gaining importance.; In this dissertation, we design and develop "power-aware and reservation-based" CPU scheduling algorithms implemented in the OS layer. ...
