Scheduling workflow tasks is a key issue in the workflow management system. Workflow Scheduling is defined as allocating suitable resources to workflow tasks in order to satisfy objective functions specified by users. This paper presents a task scheduling algorithm called LCPR algorithm for workflow tasks in heterogeneous computing environment. This algorithm focuses mainly on the tasks that are tightly coupled or that have high dependency with other tasks. This paper evaluates the algorithm with other workflow algorithms and found that LCPR gives better performance in terms of execution time and response time of the job.
