Abstract

In a heterogeneous environment, heterogeneous multi-core processors are limited to processor types and can only exe-cute on specific processors. The existing scheduling methods usually use the DAG task model to simulate, but they often ignore the communication overhead on different cores, or do not consider the corresponding relationship between processors and nodes, which leads to large scheduling time overhead, underutilization of processor resources, and low task efficiency. This paper proposed PNIF(processor-node impact factor) algorithm to solve the above problems. The algorithm introduced two scale factors which had a significant impact on the priority of the node, and added them to the calculation of the node priority to determine the task execution order. Experimental results show that compared with PEFT, HEFT and CPOP, PNIF increases the schedule length by 5.902%, 19.402% and 25.831% on average respectively, which effectively shortens the overall schedule length and improves the processor resource utilization.
