20/* oneDNN provides gemm functionality on its own using jit generated
21 * kernels. This is the only official supported option.
22 *
23 * However, for the debugging purposes we keep (internally) an ability
24 * to use cblas functions from the other libraries. The following macros
25 * affect the behavior:
26 * - USE_CBLAS allow using sgemm and other regular BLAS functionality
27 * - USE_MKL (implies USE_CBLAS) same as above + allow using igemm and
28 * packed gemm from Intel MKL library.
