项目摘要

We constitute a parallel computer with 16 processing units by using this fund and other together. Visualization of the results and the calculation processes were made on the parallel computer about the following items.・ The 2-D elastic problem and potential problem by the BEM(boundary element method).・ Flows arround 2-D wing.・ Incompressible (thermal) flow simulation.・ 2-D floor planning.・ QCD simulation.・ Statistical calculations(Mean, Variance, Histogram, Correlation, Multiple regression analysis).・ Poisson equation by SOR-BEM conbined algorithem.・ Particle collision simulation.Both of the visualization onto the display of the personal computer directly connected to the parallel computer and the visualization onto the X-window through the network are investigated.The display of the process of calculation made the debug of the program easier. The display onto the X-window through the network does not allow the large quantity of data, but is yet effective for the remote users. 3-D display of the statistical calculations enables the fast selection of the desired valuable, the alteration of the viewpoint, and the synchronous view of the mutiple results and the multiple correlation.The investigation of the communication pattern and the quantity of the data transfer shows the communication and/or the host computer may be the bottleneck, unless not only the image generation but the extraction of the imformation necessary to the user is also parallelized.We develop the parallel voxell data rendering program for the visualization fo QCD calculation, but it needs future improvement.

我们利用这笔资金和其他资金组成了一台16个处理单元的并行计算机。在并行计算机上对以下项目的结果和计算过程进行了可视化。·通过边界元法（BEM）求解二维弹性问题和势问题。·二维机翼周围的流动。·不可压缩（热）流模拟。·2-D floor planning.·QCD模拟。统计计算（均值、方差、直方图、相关性、多元回归分析）。·泊松方程的SOR-BEM组合算法。粒子碰撞模拟，研究了PC机直接与并行机相连的显示器可视化和通过网络在X窗口上的可视化，计算过程的显示方便了程序的调试。通过网络在X窗口上显示不允许大量的数据，但对于远程用户来说仍然有效。统计计算的三维显示使得能够快速选择所需的值、改变视点、同步查看多个结果和多个相关性。对通信模式和数据传输量的调查表明，通信和/或主机可能是瓶颈，我们开发了用于QCD计算可视化的并行体素数据绘制程序，但还需要进一步改进。
