C++ (Cpp) Dgemm Examples

Example #1

File: simple_dgemm.cpp Project: arbenson/fast-matmul

int main() {
  int N = 8000;
  double *A = new double[N * N];
  double *B = new double[N * N];
  double *C = new double[N * N];

  auto start = std::chrono::high_resolution_clock::now();  
  Dgemm(A, B, C, N);
  auto end = std::chrono::high_resolution_clock::now();
  auto diff = std::chrono::duration_cast<std::chrono::milliseconds>(end - start);
  std::cout << diff.count() << " ms" << std::endl;
}

Example #2

File: DgemmOverride.hpp Project: certik/nektar

 void Dgemm(NekMatrix<double, StandardMatrixTag>& result, 
            const NekMatrix<ADataType, AMatrixType>& A, const NekMatrix<BDataType, BMatrixType>& B, double alpha)
 {
     Dgemm(result, alpha, A, B);
 }

Example #3

File: DgemmOverride.hpp Project: certik/nektar

 void Dgemm(NekMatrix<double, StandardMatrixTag>& result, 
            const NekMatrix<ADataType, AMatrixType>& A, const NekMatrix<BDataType, BMatrixType>& B, double alpha, 
            double beta, const NekMatrix<CDataType, CMatrixType>& C)
 {
     Dgemm(result, alpha, A, B, beta, C);
 }
