- W2362257839 abstract "For the parallel computer system with distributed memory,the communication overhead is an all-important optimizing factor to improve the performance of parallel simulation program.To reduce the absolute communication latency between nodes,represented by a typical Synthetic Aperture Radar(SAR) imaging program,namely R-D,this paper researches on avoiding communication latency techniques for SAR imaging parallel simulation.Four important components are researched,including reducing communication numbers,reducing communication granularity,selecting appropriate communication block,and adopting efficient communication function library.Experimental results show that the SAR imaging program optimized by avoiding communication latency can present high net bandwidth utilization,and achieve obvious performance improvement." @default.
