摘要
Abstract
A GPU (graphics processing unit) implementation was presented for solving eigenvalues of a matrix. The power method and the QR method based on the GPU are used to solve the largest eigenvalue and all eigenvalues of a given matrix. The computations are compared with those by the CPU, and it is found that the computation accuracy is good, and the running time on the GPU is faster than that on the CPU by a factor of 2.7～7.6.关键词
