Bi-partition approach of directed cyclic task graph onto multicolumn processors for total completion time minimization task assignment problem

Abstract

Research on task assignment and scheduling problems began in the 1960's, and has become a popular research topic in the past few decades. In this paper, the theoretical graph application using bi-partitioning technique is presented to assign a number of tasks onto two processors. This paper considered a directed-weighted cyclic task graph. Combining the technique of reduction and bi-partitioning led to an efficient graph-mapping concept. The developed simulation model found that the proposed techniques and algorithms are easy to be implemented and minimized the computational time.
