Performance Analysis of Parallel Computing Framework on Embedded Multi-core Trustworthy Systems
Due to the environmental constraints, the use of high-performance embedded multi-core processor to solve the problem of scientific computing is the only way in a specified environment. This paper discusses the parallel computing framework and method in embedded multi-core system that used in safety critical system, and analyzes the performance of computation with three methods: the single thread, multi-thread and OpenMP in loongson processor, Intel Q8300 processor and I7 860 processor. The research shows that the parallel computing framework for multi-core processors can significantly improve the efficiency of program execution when the complexity of the case is not too high. The simulation test expressed that the parallel speedup is better in the loongson platform than Q8300 although the real performance of the processor is more faster than loongson.
