/** This OpenCL kernel computes the matrix by matrix multiplication between the matrix A (src0) and matrix B (src1) in case both matrices have not beed reshaped
 *
 * @note This OpenCL kernel works with the 32-bit floating point data type (float) and uses the fma units.
 * @note The number of elements processed along the x and y directions must be passed at compile time using -DNUM_ELEMS_PROCESSED_PER_THREAD_X and -DNUM_ELEMS_PROCESSED_PER_THREAD_Y.
 * This kernel optimally uses -DNUM_ELEMS_PROCESSED_PER_THREAD_X=4.
 * @note The number of matrix A columns must be passed at compile time using -DCOLS_A.
 * @note The optional value of scalar alpha is passed at compile time using -DALPHA=alpha
 * @note In case the matrix B has 3 dimensions and the matrix A more than 3, in order to avoid out-of-bounds reads, the number of channels of matrix B must be passed at compile time using MATRIX_B_DEPTH (i.e. -DMATRIX_B_DEPTH=16)
 *       This case can happen when GEMM is used to perform the element-wise multiplication through a batched matrix multiplication (2D Winograd) and we have multiple inputs (i.e. a = [K, M, 16, Batches], b = [N, K, 16])

 *
 * @note This OpenCL kernel works with the 32-bit floating point data type (float) and uses the fma units.
 * This OpenCL kernel is optimized for Bifrost when the number of matrix B columns is less or equal to 1000.
 * @note The number of elements processed along the x and y directions must be passed at compile time using -DNUM_ELEMS_PROCESSED_PER_THREAD_X and -DNUM_ELEMS_PROCESSED_PER_THREAD_Y.
 * This kernel optimally uses -DNUM_ELEMS_PROCESSED_PER_THREAD_X=2.
 * @note The number of matrix A columns must be passed at compile time using -DCOLS_A.
 * @note The optional value of scalar alpha is passed at compile time using -DALPHA=alpha if alpha!=1.0f.
 * @note In case the matrix B has 3 dimensions and the matrix A more than 3, in order to avoid out-of-bounds reads, the number of channels of matrix B must be passed at compile time using MATRIX_B_DEPTH (i.e. -DMATRIX_B_DEPTH=16)
 *       This case can happen when GEMM is used to perform the element-wise multiplication through a batched matrix multiplication (2D Winograd) and we have multiple inputs (i.e. a = [K, M, 16, Batches], b = [N, K, 16])

/** This OpenCL kernel computes the matrix by matrix multiplication between the matrix A (src0) and matrix B (src1) in case both matrices have not beed reshaped
 *
 * @note This OpenCL kernel works with fixed point data types QS16
 * @note The number of elements processed along the x and y directions must be passed at compile time using -DNUM_ELEMS_PROCESSED_PER_THREAD_X and -DNUM_ELEMS_PROCESSED_PER_THREAD_Y
 * @note The number of matrix A columns, the number of elements processed per thread along the Y direction and the alpha's value need to be passed at compile time using -DCOLS_A, -DNUM_ELEMS_PROCESSED_PER_THREAD_Y and -DALPHA
 * @note The fixed point position need to be passed at compile time using -DFIXED_POINT_POSITION
 * @note The optional alpha value must be passed in 16 bit fixed point format using -DALPHA
 * @note In case the matrix B has 3 dimensions and the matrix A more than 3, in order to avoid out-of-bounds reads, the number of channels of matrix B must be passed at compile time using MATRIX_B_DEPTH (i.e. -DMATRIX_B_DEPTH=16)
 *       This case can happen when GEMM is used to perform the element-wise multiplication through a batched matrix multiplication (2D Winograd) and we have multiple inputs (i.e. a = [K, M, 16, Batches], b = [N, K, 16])
