/** This OpenCL kernel is optimized for Bifrost. It computes the matrix multiplication between matrix A (src0) and matrix B (src1)
 *  Matrix A and matrix B must be reshaped respectively with @ref gemm_interleave4x4_32bit and @ref gemm_transpose1x4 before running the matrix multiplication
 *
 * @note The number of columns of matrix B and the optional alpha's value need to be passed at compile time using -DCOLS_B and -DALPHA
 * @note The multiplication factor for the transposition width (mult_transpose1xW_width) must be passed at compile time using -DMULT_TRANSPOSE1XW_WIDTH (i.e. -DMULT_TRANSPOSE1XW_WIDTH=2)
 * @note The multiplication factor for the height of the 4x4 interleaved block must be passed at compile time using -DMULT_INTERLEAVE4X4_HEIGHT (i.e. -DMULT_INTERLEAVE4X4_HEIGHT=2)
 * @note The multiplication factor for the height of the 4x4 interleaved block must be passed at compile time using -DMULT_INTERLEAVE4X4_HEIGHT (i.e. -DMULT_INTERLEAVE4X4_HEIGHT=2)
 * @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 In case the output has to be reinterpreted as a 3D tensor (i.e. output of convolution layer), the following information must be passed at compile time:
 *       -# REINTERPRET_OUTPUT_AS_3D: To reinterpret the output as 3D
 *       -# HEIGHT_GEMM3D: The height of the output in case it has to be reinterpreted as a 3D tensor.
 *       -# DEPTH_GEMM3D: The depth of the output in case it has to be reinterpreted as a 3D tensor
 *          (HEIGHT_GEMM3D * DEPTH_GEMM3D) = columns matrix A NOT reshaped

/** This OpenCL kernel computes the matrix by matrix multiplication between the matrix A (src0) and matrix B (src1) in case both matrices have not been reshaped
 *
 * @note This OpenCL kernel works with floating point data types (F16/F32)
 * @note The floating point data type must be passed at compile time using -DDATA_TYPE (e.g. -DDATA_TYPE=float)
 * @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 and the optional alpha's value need to be passed at compile time using -DCOLS_A and -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])
 *
 * @note In case the output has to be reinterpreted as a 3D tensor (i.e. output of convolution layer), the following information must be passed at compile time:
 *       -# REINTERPRET_OUTPUT_AS_3D: To reinterpret the output as 3D
 *       -# HEIGHT_GEMM3D: The height of the output in case it has to be reinterpreted as a 3D tensor.
 *       -# DEPTH_GEMM3D: The depth of the output in case it has to be reinterpreted as a 3D tensor
 *          (HEIGHT_GEMM3D * DEPTH_GEMM3D) = columns matrix A NOT reshaped

/** This OpenCL kernel computes the matrix by matrix multiplication between the matrix A (src0) and matrix B (src1) in case both matrices have not been 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 In case the output has to be reinterpreted as a 3D tensor (i.e. output of convolution layer), the following information must be passed at compile time:
 *       -# REINTERPRET_OUTPUT_AS_3D: To reinterpret the output as 3D
 *       -# HEIGHT_GEMM3D: The height of the output in case it has to be reinterpreted as a 3D tensor.
 *       -# DEPTH_GEMM3D: The depth of the output in case it has to be reinterpreted as a 3D tensor
 *          (HEIGHT_GEMM3D * DEPTH_GEMM3D) = columns matrix A NOT reshaped

/** This OpenCL kernel computes the matrix by matrix multiplication between the matrix A (src0) and matrix B (src1) in case both matrices have not been reshaped
 *
 * @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])
 *
 * @note In case the output has to be reinterpreted as a 3D tensor (i.e. output of convolution layer), the following information must be passed at compile time:
 *       -# REINTERPRET_OUTPUT_AS_3D: To reinterpret the output as 3D
 *       -# HEIGHT_GEMM3D: The height of the output in case it has to be reinterpreted as a 3D tensor.
 *       -# DEPTH_GEMM3D: The depth of the output in case it has to be reinterpreted as a 3D tensor
 *          (HEIGHT_GEMM3D * DEPTH_GEMM3D) = columns matrix A NOT reshaped

/** 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 16-bit floating point data type (half) 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 In case the output has to be reinterpreted as a 3D tensor (i.e. output of convolution layer), the following information must be passed at compile time:
 *       -# REINTERPRET_OUTPUT_AS_3D: To reinterpret the output as 3D
 *       -# HEIGHT_GEMM3D: The height of the output in case it has to be reinterpreted as a 3D tensor.
