Study and realization of process scheduling policy facing user

Aiming at the problem of Linux process scheduling policy just regards the system capability and neglects user service, the paper presents a kind of process scheduling policy facing to user according to the discrepancy of process quantity every user owned, which invokes Linux dynamic priority scheduling policy, fair share scheduling policy and self-adapting fair share scheduling policy in order to meet the every user´s need in whole system to most degree and realize the fair principle of process scheduling. In the realization process, the author settles the problem of decision-making account and introduces the dynamic right adjusting mechanism to realize self-adapting fair share arithmetic. The experiment result indicates that the process scheduling policy is effective and valuable applying on the time-sharing system which regards user´s contentment degree.
