IF(INCY==1)THEN #.. #Onentry,TRANSspecifiestheoperationtobeperformedas This call to the DO100,J=1,N The one-dimensional arrays in the exercises store the matrices by placing the elements of each column in successive cells of the arrays. 3) Another possibility is to use operations different from N, for example the transpose T of the hermitian C, for example this two codes are equivalent but the second is faster and use less memory: notice that the LDA and LDB specify the entry dimension of the matrix A and B, therefore in the second case the entry dimension is the first dimension of the original matrices A and B, while in the first example it corresponds to the one of transpose(A) and transpose(B). This exercise demonstrates declaring variables, storing matrix values in the arrays, and calling dgemm to compute the product of the matrices. In this paper we will present a detailed study on tuning double-precision matrix-matrix multiplication (DGEMM) on the Intel Xeon E5-2680 CPU.
