One Solution for Multiple Environments

Intel® Math Kernel Library (Intel® MKL) optimizes code with minimal effort for future generations of Intel® processors. It is compatible with your choice of compilers, languages, operating systems, and linking and threading models.

  • Features highly optimized, threaded, and vectorized math functions that maximize performance on each processor family
  • Uses industry-standard C and Fortran APIs for compatibility with popular BLAS, LAPACK, and FFTW functions—no code changes required
  • Dispatches optimized code for each processor automatically without the need to branch code
  • Provides Priority Support that connects you directly to Intel engineers for confidential answers to technical questions
