Abstract:

The scheduling algorithms using the exact process execution time have not been put into practice and execution time is treated as a random variable and some of the methods are statistically estimate it from past observations and some of them collect more data like source process algorithm for estimation but, all of them try to collect more data in deferent ways to estimate a good time for the future execution time of process and make themselves power full than each other but none of them can change their estimation during the time that process is running and this is the weakness. In this study there is a new technique-with the help of the compiler-for calculating the exact process execution time and adding some new data inside process source code to be useful for other algorithms to make them more power full and more. This will pave the way for executing these scheduling algorithms. Furthermore, using this new technique, a new horizon will be opened in CPU scheduling. Finally, a new scheduling algorithm called Shortest Remaining Cycle will be introduced in which the process itself plays a role in its scheduling.
