Hello!
I installed on my computer Intel® C++ Studio XE for Windows 2013 SP1 and Microsoft Visual Studio Pro 2012. Then I followed the instructions that I watched on this video http://software.intel.com/en-us/videos/using-the-intel-c-compiler-with-m.... In order to use MKL I followed these instructions
For the Visual Studio* 2010/2012 development system:
- Go to Project>Properties>Configuration Properties>Intel Performance Libraries.
- Change the Use MKL property setting by selecting Parallel, Sequential, or Cluster as appropriate.
I wanted to run the following example that I read on the tutorial
/* C source code is found in dgemm_example.c */ #define min(x,y) (((x) < (y)) ? (x) : (y)) #include <stdio.h> #include <stdlib.h> #include "mkl.h" int main() { double *A, *B, *C; int m, n, k, i, j; double alpha, beta; printf ("\n This example computes real matrix C=alpha*A*B+beta*C using \n"" Intel® MKL function dgemm, where A, B, and C are matrices and \n"" alpha and beta are double precision scalars\n\n"); m = 2000, k = 200, n = 1000; printf (" Initializing data for matrix multiplication C=A*B for matrix \n"" A(%ix%i) and matrix B(%ix%i)\n\n", m, k, k, n); alpha = 1.0; beta = 0.0; printf (" Allocating memory for matrices aligned on 64-byte boundary for better \n"" performance \n\n"); A = (double *)mkl_malloc( m*k*sizeof( double ), 64 ); B = (double *)mkl_malloc( k*n*sizeof( double ), 64 ); C = (double *)mkl_malloc( m*n*sizeof( double ), 64 ); if (A == NULL || B == NULL || C == NULL) { printf( "\n ERROR: Can't allocate memory for matrices. Aborting... \n\n"); mkl_free(A); mkl_free(B); mkl_free(C); return 1; } printf (" Intializing matrix data \n\n"); for (i = 0; i < (m*k); i++) { A[i] = (double)(i+1); } for (i = 0; i < (k*n); i++) { B[i] = (double)(-i-1); } for (i = 0; i < (m*n); i++) { C[i] = 0.0; } printf (" Computing matrix product using Intel® MKL dgemm function via CBLAS interface \n\n"); cblas_dgemm(CblasRowMajor, CblasNoTrans, CblasNoTrans, m, n, k, alpha, A, k, B, n, beta, C, n); printf ("\n Computations completed.\n\n"); printf (" Top left corner of matrix A: \n"); for (i=0; i<min(m,6); i++) { for (j=0; j<min(k,6); j++) { printf ("%12.0f", A[j+i*k]); } printf ("\n"); } printf ("\n Top left corner of matrix B: \n"); for (i=0; i<min(k,6); i++) { for (j=0; j<min(n,6); j++) { printf ("%12.0f", B[j+i*n]); } printf ("\n"); } printf ("\n Top left corner of matrix C: \n"); for (i=0; i<min(m,6); i++) { for (j=0; j<min(n,6); j++) { printf ("%12.5G", C[j+i*n]); } printf ("\n"); } printf ("\n Deallocating memory \n\n"); mkl_free(A); mkl_free(B); mkl_free(C); printf (" Example completed. \n\n"); return 0; }
But I can't run it. The results I got are
Warning 1 warning D9025: overriding '/D__INTEL_COMPILER=1400' with '/U__INTEL_COMPILER'
Warning 2 warning D9002: ignoring unknown option '/QaxSSE4.2'
Warning 3 warning D9002: ignoring unknown option '/QxAVX'
Warning 4 warning D9002: ignoring unknown option '/Qfast-transcendentals'
Error 5 error C1083: Cannot open include file: 'mkl.h': No such file or directory
Could you please tell what I have done wrong?
Thank you in advance.
