摘要

The performance of the parallel out-of-core Higher-order Method of Moments (HoMoM) is analysed in this paper. The I/O to hard disks significantly affects the performance of the out-of-core algorithm. In order to reduce the I/O time, solid state drives (SSD) with high read and write speeds are utilized. The size of the in-core buffer allocated to each process, IASIZE, is tuned to achieve the optimum performance of the out-of-core algorithm. Numerical results show that the out-of-core algorithm using SSD exhibits better performance than that using SAS hard drives. As a challenging application, a slot array with 2068 elements is analysed using this method.
