摘要

95%的大尺寸问题。对于512个节点上的1.62亿个粒子，实现的粒子传递时间为115 nsecs/粒子/时间步。与单处理器Cray C90的性能相比，这代表了58倍的加速。代码采用有限差分跃蛙法进行场求解，比并行计算机上的快速傅里叶变换效率高得多。本文还将讨论该代码在128节点的Cray T3D上的性能。

Approximation Of The Bounded Plasma Model By The Plasma And The Sheath Models

of 2 95% for large size problems. The particle pash time achieved is 115 nsecs/particle/time step for 162 mdlion particles on 512 nodes. Comparing with the performance on a single processor Cray C90, this represents a factor of 58 speedup. The code uses a finite-difference leap frog method for field solve which is significantly more efficient than fast Fourier transforms on parallel computers. The performance of this code on the 128 node Cray T3D will also be discussed.
