Abstract

Abstract

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.
