Priority based Performance Improved Algorithm for Meta-task Scheduling in Cloud environment

Abstract

Computing in Cloud is a topical skill that disquiet with allocation of computing resources and services on pay- per- use basis. To access remote computers, scheduling is a key task. Scheduling of task is a NP-complete problem. It is additional obscure in cloud computing atmosphere. To achieve improved performance of cloud resource, successful and proficient scheduling methodologies are needed. This paper proposes, a Meta-task Scheduling algorithm, Priority based Performance Improved Algorithm. It considers the user priority of meta-tasks. The high priority meta-task set is scheduled based on Min-Min algorithm and then the normal priority meta-task set is scheduled based on Max-Min algorithm. The proposed algorithm gives minimum makespan and better resource utilization.
