E. Major elements of scheduling The scheduling of Linux operating system is priority based scheduling. It is to make scheduling policies into the core of Linux which called Kernel for multi-tasking processes. There are two different scheduling: real time and normal, for handling large data processes performance balance and sharing CPU equally in the system. In the scheduling of Kernel, each process has a priority value which ranges from 1 to 139. 1 is the highest priority level. 139 is the lowest priority level. The real time priorities range from 1 to 99 and the normal priorities range from 100 to 139. The smaller number of priority value, the priority is higher. All real time programs have a higher priority than normal programs in the system. In Linux scheduling is implemented by a class named sched_class (Seeker, 2013). The purpose of this class is to handle the multi-tasking processes by scheduler skeleton and data algorithms. As discussed above, the priority value is very important for the scheduling, so how the system set the priority in the Linux for assigning which is in higher priority? It depends on the types of the
