MKL库中基本线性代数子程序,BLAS(Basic Linear Algebra Subprograms)库,是一个API标淮,用以规范发布基础线性代数操作的数值库(如向量或矩阵乘法)。其中CBLAS是BLAS的C语言接口。 库中前缀用来区分所支持处理的数据类型。 | 前缀 | 描述 | 函数名系列
{1.0, 1.0, 1.0}; // Result vector y (size m), initially zero double y[] = {0.0, 0.0, 0.0}; // Scalar multipliers double alpha = 1.0, beta = 0.0; // Perform y = alpha * A * x + beta * y cblas_dgemv(CblasRowMajor, CblasNoTrans, m, n, alpha, A, n, x, 1, beta, ...
So, ideally using cblas_dgemv() within openmp parallel region should work. But my test doesn'tseem to work. I thought it could be due to data race issue, so I also added #pragma openmp barrierbefore cblas_dgemv() but it doesn't solve the problem.Yes, moving cblas_dgemv()...

Trying to run one of the examples, cblas_dgemvx to assess MKL for my project. I need to do very fast matrix-vector operations. The c file builds but link fails. Settings are : Intel performance libraries - Use MKL - sequential, Use ILP64 - yes Includes: C:\P...
