A Novel Approach to Multiagent based Scheduling for Multicore Architecture

In a Multicore architecture, eachpackage consists of large number of processors. Thisincrease in processor core brings new evolution inparallel computing. Besides enormous performanceenhancement, this multicore package injects lot ofchallenges and opportunities on the operating systemscheduling point of view. We know that multiagentsystem is concerned with the development andanalysis of optimization problems. The main objectiveof multiagent system is to invent some methodologiesthat make the developer to build complex systems thatcan be used to solve sophisticated problems. This isdifficult for an individual agent to solve. In this paperwe combine the AMAS theory of multiagent systemwith the scheduler of operating system to develop anew process scheduling algorithm for multicorearchitecture. This multiagent based schedulingalgorithm promises in minimizing the average waitingtime of the processes in the centralized queue and alsoreduces the task of the scheduler. We actuallymodified and simulated the linux 2.6.11 kernel processscheduler to incorporate the multiagent systemconcept. The comparison is made for different numberof cores with multiple combinations of process and theresults are shown for average waiting time Vs numberof cores in the centralized queue
