At the end of summer, the bear feasts on berries and small woodland animals. During autumn, it devours acorns and salmon. It gained a fifth of the weight it needed from berries during summer, and during autumn, it gained twice that amount from acorns. Salmon made up half of the remaining weight it had needed to gain. How many pounds did it gain eating small animals?\nAnswer:<|im_end|>\n<|im_start|>assistant\nThe bear gained 1 / 5 * 1000 = <<1/5*1000=200>>200 pounds from berries.\nIt gained 2 * 200 = <<2*200=400>>400 pounds from acorns.\nIt still needed 1000 - 200 - 400 = <<1000-200-400=400>>400 pounds.\nThus, it gained 400 / 2 = <<400/2=200>>200 pounds from salmon.\nTherefore, the bear gained 400 - 200 = <<400-200=200>>200 pounds from small animals.\n#### 200<|im_end|>\n<|im_start|>user\nQuestion: Janet’s ducks lay 16 eggs per day.

2025 05:57:40 +0000 Subject: [PATCH 12/36] feat: add Linear layer quantization strategy framework - Add LinearQuantizationStrategy interface supporting weight+activation quantization - Support layer-type-specific strategies (attn/mlp/other) - Add registry system for linear quantization strategies - Add Config fields: linear_attn_weight_dtype, linear_mlp_weight_dtype, linear_attn_act_dtype, linear_mlp_act_dtype - Integrate factory to inject strategies into QuantizationContext - Add dynamic dispatch in Linear.forward() based on quant_kind - Tag Linear layers in models (dream/llada/sdar/fast_dllm_v2) with quant_kind - Add placeholder strategies (stub) that raise NotImplementedError for non-bf16 dtypes - Add unit tests for registry/factory/dispatch behavior - Default bf16 behavior unchanged (fully backward compatible) All non-bf16 paths currently raise NotImplementedError with clear error messages, providing stable interface for future kernel/packed weight

[PATCH 13/36] feat: implement W8A16 Linear quantization strategy (int8 weight + bf16 activation) - Add LinearInt8W8A16Strategy with per-channel symmetric quantization - Reference implementation using Python dequantization + F.linear - Quantization: per-output-channel scales, int8 weight storage - Activation: remains bf16 (no activation quantization) - Update tests to verify W8A16 strategy (quantization/forward correctness) - Update placeholder documentation with implementation status Performance notes: - Current implementation quantizes weights on every forward (no caching) - Future optimization: lazy cache quantized weights per module instance - Future optimization: replace F.linear with custom int8 GEMM kernel This provides a working reference implementation for W8A16 quantization, enabling correctness validation before moving to optimized kernels. --- .../utils/quantization/strategies/__init__.py | 2 + .../strategies/linear_int8_w8a16.py | 171 ++++++++++++++++++

Move per-channel scale multiplication from K-loop weight dequant to output column scaling - Mathematical equivalence: (A @ (q*s)^T) = (A @ q^T) * s for per-channel scales - Reduces register pressure, type conversions, and intermediate buffers in hot path - Applied to both w8a16_gemm and w4a16_gemm kernels - Fix test_w8a16_tilelang_kernel_correctness: use masked relative error check - Avoids false failures when ref_output is near zero - Only checks relative error where ref_output.abs() > 1.0 - Improve test_w8a16_generation.py cleanup logic - Ensure proper cleanup (destroy_process_group, empty_cache, gc.collect) even on exceptions - Add W4A16 strategy implementation and test script --- diffulex/layer/linear.py | 29 +- .../utils/quantization/strategies/__init__.py | 2 + .../strategies/linear_int4_w4a16.py | 460 ++++++++++++++++++ diffulex_kernel/python/linear_kernels.py | 260 ++++++++-- examples/test_w4a16_generation.py | 262 ++++++++++ examples/test_w8a16_generation.py | 50 +- .../python/test_linear_quantization_module.py | 175 ++++++- 7 files changed, 1179 insertions(+), 59 deletions(-) create mode 100644 diffulex/utils/quantization/strategies/linear_int4_w4a16.py create mode 100755 examples/test_w4a16_generation.py diff --git a/diffulex/layer/linear.py b/diffulex/layer/linear.py index ebbc1a0..d3a8183 100755 --- a/diffulex/layer/linear.py +++ b/diffulex/layer/linear.py @@ -106,9 +106,10 @@ def _maybe_quantize_loaded_weight_param( loaded_shard_id: object = None, expected_shard_ids: set[object] | None = None, ) -> None: -

-- Running max 的内存管理：需要在设备上维护 tensor，需要考虑设备一致性 -- Scale 计算性能：每次 forward 时更新 running max 和计算 scale 有开销，但这是必要的 -- 多线程/多进程安全：如果 Attention 层在多线程环境中共享，需要考虑同步 - -### High Risk - -- **Scale 一致性**：如果 load 在 store 之前被调用，需要确保 scale 正确初始化 -- **Cache 重置时机**：当 kv_cache_dtype 改变时，需要重置 running max，但如何检测改变需要仔细处理 - -### Mitigation Strategies - -1. **向后兼容性**：所有新增参数都有默认值，不会破坏现有代码 -2. **设备一致性**：确保 running max tensor 与 k/v tensor 在同一设备上 -3. **Scale 初始化**：在 load 之前检查 scale 是否存在，如果不存在则先计算 -4. **Dtype 变更检测**：通过比较 `self.kv_cache_dtype_cache` 与当前 `kv_cache_dtype` 来检测变更 - -## Testing Strategy - -### Unit Tests - -1. **Test running max update**: - -- 验证首次调用时正确初始化 -- 验证后续调用时正确更新（取最大值） -- 验证 dtype 变更时正确重置 - -2. **Test scale computation**: - -- 验证 FP8 时正确计算 scale -- 验证非 FP8 时返回 None -- 验证 scale 形状正确（[num_kv_heads]） - -3. **Test context kv_cache_dtype**: - -- 验证 causal_lm context 正确设置和获取 kv_cache_dtype -- 验证 diffusion_lm context 从 config 获取 kv_cache_dtype - -### Integration Tests - -1. **Test attention layer with FP8**: - -- 使用 FP8 KV cache 运行完整 forward pass -- 验证 store 和 load 正确传递参数 -- 验证量化/反量化正确性（可复用现有 roundtrip 测试思路） -- 验证多次 forward 调用时 running max 正确累积 - -2. **Test backward compatibility**: - -- 使用默认 bf16 运行，确保行为不变 -- 验证未指定 kv_cache_dtype 时使用默认值 -

2026 14:02:40 +0000 Subject: [PATCH 36/36] feat: integrate Marlin/AllSpark INT8 W8A16 quantization strategy MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit 主要新增内容： 1. **Marlin/AllSpark INT8 W8A16 量化策略集成**： - 新增 linear_marlin_int8_w8a16.py：实现基于 vLLM AllSpark kernel 的 W8A16 量化策略 - 新增 diffulex_kernel/csrc/marlin/：vendored vLLM 的 AllSpark CUDA kernels * allspark_qgemm_w8a16.cu: W8A16 fused GEMM kernel * allspark_repack.cu: N32K16 权重重排 kernel * allspark_utils.cuh: 工具函数和数据结构 * torch_bindings_marlin.cpp: PyTorch C++ 绑定 - 新增 diffulex_kernel/python/marlin_ops.py：Python 接口用于 JIT 编译和加载 Marlin/AllSpark kernels 2. **量化策略注册更新**： - 在 registry.py 中添加 'marlin' 别名支持（映射到 marlin_int8） - 在 strategies/__init__.py 中导入新的策略 3. **性能改进**： - Marlin W8A16 策略显著提升了 Prefill 吞吐量（从 4518.92 tok/s 提升到 9520.91 tok/s，约 2.1 倍） - Decode 吞吐量接近 BF16 基线（23.16 tok/s vs 23.36 tok/s） - 支持与 FP8 KV cache 组合使用 4. **其他改进**： - 优化了多个量化策略的实现 - 改进了 KV cache 管理 - 增强了 profiler 功能 - 新增了多个 benchmark 配置文件 --- .../results_2026-01-14T02-04-10.705764.json | 181 ++++++ .../results_2026-01-14T02-11-04.186162.json | 181 ++++++ .../results_2026-01-14T03-41-09.193046.json
