用于并行计算的PC集群系统构建*

在注射成形模拟研究过程中，涉及材料的牛顿和非牛顿黏性流动模拟和注射成形后期的冷却过程模拟，以及随时间变化各处的压力变化等科学和工程领域经常应用大规模科学计算。随着基于网格的计算和数据处理日益复杂，很多计算一般PC系统无法满足要求，需要超级计算环境。因为不断追求更高的计算精度和日益复杂的对象而扩大计算规模,传统的串行处理方式难以满足这些要求。因此，现代高性能计算的低成本、高效率成为选择并行计算的解决方式。重点阐述如何构建一个用于并行计算的PC集群系统，结合实例阐明MPI的实现方法，以及对PC集群系统进行了性

PC cluster system build for parallel computing

The materials involved in the Newton and Newton viscous flow simulation and the latter part of the cooling process simulation in the injection molding,and the changes in the pressure during the simulation of injection molding process need large-scale scientific computing.As grid-based computing and data-processing increasingly complex,many PC computing systems can not meet the general requirements,need super computing environment to finish the computing job.as constant pursuit of higher accuracy and the tar...
