摘要

我们在美国宇航局戈达德太空飞行中心的并行计算机上分析和测试了第五代 PSU/NCAR 中尺度模型 MM5 的性能。我们展示了 MM5 代码在 Cray J90、Cray T3E 和 PC 集群上的扩展情况。更确切地说，我们对耗时、负载平衡、速度提升、每秒浮点运算次数以及性能与成本的关系感兴趣。通过两个测试问题获得的结果表明，MM5 在上述计算机上的效率很高，尤其是在处理大型问题时。

Implementing MM5 on NASA Goddard Space Flight Center computing systems: a performance study

We analyze and test the performance of the fifth-generation PSU/NCAR mesoscale model MM5 on parallel computers at NASA Goddard Space Flight Center. We show how MM5 code scales on the Cray J90, the Cray T3E and a cluster of PCs. More precisely, we are interested in finding the elapsed time, load balancing, speedup, number of floating point operations per second, and performance versus cost. Results obtained with two test problems show the efficiency of MM5 on the above computers especially with large size problems.
