摘　　要：研究了多核计算机上OpenMP+VC++编程模式的并行程序,并在双核和四核计算机上分别使用传统算法和并行算法计算数列求和、矩阵乘积及矩阵Cholesky分解。试验表明,传统串行程序只能利用多核计算机的一个核资源,而采用Open MP程序的并行效率很高。Parallel programming in VC＋＋ using OpenMP on multi-core computers are studied. The serial and concurrent experiments of summation,matrix-matrix multiplication,and Cholesky factorization are implemented on 2-core and 4-core computers respectively. Experiment results show that the serial program can only use one core of multi-core computerso Meanwhile, the parallel efficiency of the program using OpenMP is very high.
