Abstract

A production 3-D Beam and Warming implicit Navier Stokes code has been implemented on the NCUBE hypercube using the grid allocation scheme of J. Bruno and P.R. Capello (see Proc. 3rd Conf. on Hypercube Concurrent Computers and Applications, p.1073-87, 1988). Predicted (32-b) performance on 1024 nodes is 67.1 MFLOPS. Efficiencies of 70% are attainable for implicit algorithms, although constant-memory scaled performance is found to decrease with increasing number of nodes, unlike the case for explicit implementations.<>

在NCUBE超立方体上实现Beam和Warming隐式因子方案的性能分析

使用J. Bruno和P.R. Capello的网格分配方案(参见Proc. 3rd Conf. on hypercube Concurrent Computers and Applications, p.1073-87, 1988)，在NCUBE超立方体上实现了生产3-D Beam和Warming隐式Navier Stokes代码。在1024个节点上预测(32-b)性能为67.1 MFLOPS。隐式算法的效率可以达到70%，尽管发现恒定内存缩放性能随着节点数量的增加而降低，这与显式实现的情况不同。
