| 2320 | * @note This OpenCL kernel works with the 32-bit floating point data type (float) and uses the fma units. |
| 2321 | * This OpenCL kernel is optimized for Bifrost when the number of matrix B columns is less or equal to 1000. |

| 2324 | * @note The number of matrix A columns must be passed at compile time using -DCOLS_A. |

Gian Marco Iodice | fd68311 | 2018-04-17 09:52:44 +0100 | [diff] [blame] | 3056 | * @note This OpenCL kernel works with the 16-bit floating point data type (half) and uses the fma units. |
| 3057 | * @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. |
| 3058 | * This kernel optimally uses -DNUM_ELEMS_PROCESSED_PER_THREAD_X=4. |
| 3059 | * @note The number of matrix A columns must be passed at compile time using -DCOLS_A. |
| 3060 | * @note The optional value of scalar alpha is passed at compile time using -DALPHA=alpha |
| 3061 | * @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) |
| 3062 | * 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]) |
