并行NAS Benchmarks的需求特征分析

REQUIREMENT CHARACTERISTICS ANALYSIS OF THE NAS PARALLEL BENCHMARKS

文中采用阶段并行模型（ｐｈａｓｅｐａｒａｌｅｌｍｏｄｅｌ），分析了并行ＮＡＳｂｅｎｃｈｍａｒｋｓ的结构和资源需求特征，得到了其对内存、Ｉ／Ｏ及通信的时延和带宽等需求的参数值．这些量化的参数对各类并行计算机的设计和评价具有一定的参考价值．

Here characterized are the structure and resource requirements of the NAS parallel benchmarks.The phase parallel model is used to obtain parameter values for memory,I/O,and communication latency and bandwidth requirements.These quantitative parameters are useful in the design and evaluation of various parallel computers.
