- * DPP8 version of blockwise GEMM algorithm. It uses DPP8 instruction modifier to limit
- * the data loaded from LDS to registers.
- *
- * The algorithm groups threads into groups of size `dpp8::lane_group_size` and splits the matrix C
- * between them in such a way that threads from the same group need the same chunk of either
- * matrix A (or B, respectively). Without the usage of DPP8, each thread would need to load the
- * whole chunk from LDS to its own register space.
- * Usage of DPP8 modifiers allow each thread to load less data, exactly `1 / dpp8::lane_group_size`
- * of the chunk, and then share that data with other threads from the same lane group.
- *
- * Assumptions coming from the usage of DPP8:
- *   1. `BM10BN10ThreadClusterBM10Xs[1] == dpp8::lane_group_size` or
- *      `BM10BN10ThreadClusterBN10Xs[1] == dpp8::lane_group_size` -
- *        - it makes consecutive `dpp8::lane_group_size` threads use the same chunk of either
- *          matrix A or B;
- *        - based on these values we determine which matrix to share.
- *   2. `BM1PerThreadBM11 % dpp8::lane_group_size == 0` (if sharing A) or
- *      `BN1PerThreadBN11 % dpp8::lane_group_size == 0` (if sharing B) -
- *        - we have to make sure that the data to split is divisible by the number of
- *          threads in the group.
- *
- * General algorithm:
- * C[BM0, BM1, BN0, BN1] += transpose(A[K, BM0, BM1]) * B[K, BN0, BN1]
- * A and B are visible to the whole block, C is distributed among each thread
- * Assume:
- *   1. A:
- *     1. ABlockDesc_BK0_BM_BK1 is known at compile-time
- *     2. ABlockBuffer is DynamicBuffer
- *   2. B:
- *     1. BBlockDesc_BK0_BN_BK1 is known at compile-time
- *     2. BBlockBuffer is DynamicBuffer
- *   3. C:
- *     1. CThreadDesc_BM0_BM11_BN0_BN11 is known at compile-time
- *     2. CThreadBuffer is StaticBuffer
- *   4. BM10BN10ThreadClusterBM10Xs::Size() = BM10BN10ThreadClusterBN10Xs::Size() == 2
