Write an MPI program that solves a set of linear equations Ax = b with the 并行计算 Jacobi method. The root process reads the matrix A and the vector b from files. The file names have to be specified by the user as parameters.-Write an MPI p

calculate vector x in Ax=b equation of the upper triangle matrix using pipeline mpi

稀疏矩阵向量乘法（Sparse Matrix-Vector Multiplication, SpMV）在许多科学计算程序中都有广泛的应用。数据矩阵A 是稀疏的，输入向量x 和输出向量y是稠密的。 y = Ax(Sparse Matrix-Vector Multiplication (SpMV) is widely used in many scientific computing programs. The data matrix A is sparse, the input vector x
