中文摘要：
核外求解计算可以解决计算机内存不足的问题,但由于硬盘读写速度的限制,使得问题的求解速度过慢。针对上述问题,该文采用了核外并行求解方法;为充分利用各计算节点的内存和减少读写数据的时间,将矩阵按分块依次并行消元,加快了问题求解速度。计算了金属立方体、金属组合体和飞机模型的双站雷达散射截面,并与常规核外并行方法、核内并行方法进行了比较。结果表明,该文方法可快速、有效地求解电大目标的电磁散射问题,而且不损失计算精度。
英文摘要：
The problems,which can not be calculated due to the insufficient of memory,can be solved with out-of-core solving method,but it takes too longer time because the speed limit of the data reading/writing on the disk.To solve the above problem,parallel out-of-core solving method is used.In order to use the RAM sufficiently and reduce the reading/writing time,the matrix is eliminated by looping over blocks in parallel,so the solving speed is accelerated.The bistatic RCS of a PEC cube,a PEC union and a plane model are calculated,respectively.Parallel block out-of-core solver,which is proposed in this paper,is compared with usual parallel out-of-core solver and parallel in-core solver.The results indicate that the method in this paper can effectively solve the scattering problems of electrically large objects,and the calculation precision is not lost.
