 We also give our upcoming optimizations previews, including an Intel AMX-accelerated kernel and a selective expert activation method, which will significantly enhance performance. With V0.3-preview, we achieve up to 286 tokens/s for prefill, making it up to **28× faster than llama.cpp** for local inference.

 > **Feb 15, 2025**: KTransformers V0.2.1: Longer Context (from 4K to 8K for 24GB VRAM) & Slightly Faster Speed （+15%) (Up to 16 Tokens/s), update docs [here](./doc/en/DeepseekR1_V3_tutorial.md) and [online books](https://kvcache-ai.github.io/ktransformers/).
 
 We speed up the decode and prefill speed a littlt bit. The reason for the limited performance improvement mainly lies in the fact that the inference process is still constrained by the CPU's computational speed and memory bandwidth. The MLA part handled by the GPU accounts for a relatively small proportion.
 
 Besides the improvements in speed, we've also significantly updated the documentation to enhance usability, including:<br>
+
 - Added Multi-GPU configuration tutorial.
 - Consolidated installation guide.
 - Add a detailed tutorial on registering extra GPU memory with ExpertMarlin;

 ## Some Explanations
-1. Also we want to make further use of our two NUMA nodes on Xeon Gold cpu. 
-To avoid the cost of data transfer between nodes, we "copy" the critical matrix on 
-both nodes which takes more memory consumption but accelerates the prefill and decoding process.
-But this method takes huge memory and slow when loading weights, So be patient when loading
-and monitor the memory usage. We are going to optimize this huge memory overhead. Stay tuned~ <br>
-2. The command args `--cpu_infer 65` specifies how many cores to use (it's ok that it exceeds the physical number, 
-but it's not the more the better. Adjust it slightly lower to your actual number of cores)<br>

 ### Faster
+
 * The FlashInfer (https://github.com/flashinfer-ai/flashinfer) project is releasing an even more efficient fused MLA operator, promising further speedups
 * vLLM has explored multi-token prediction in DeepSeek-V3, and support is on our roadmap for even better performance
 * We are collaborating with Intel to enhance the AMX kernel (v0.3) and optimize for Xeon6/MRDIMM

 ### Easier
+
 * Official Docker images to simplify installation
 * Fix the server integration for web API access
 * Fix the local chat only accepting a single line prompt (currently \n begins generating prompt)
 * Support for more quantization types, including the highly requested dynamic quantization from unsloth

+# Balance Serve backend (multi-concurrency) for ktransformers
+
+## KTransformers v0.2.4 Release Notes
+We are excited to announce the official release of the long-awaited **KTransformers v0.2.4**!
+In this version, we’ve added highly desired **multi-concurrency** support to the community through a major refactor of the whole architecture, updating more than 10,000 lines of code.
+By drawing inspiration from the excellent architecture of sglang, we have implemented high-performance asynchronous concurrent scheduling in C++, including features like continuous batching, chunked prefill, and more. Thanks to GPU sharing in concurrent scenarios, overall throughput is also improved to a certain extent. The following is a demonstration:
+
+
+
+https://github.com/user-attachments/assets/faa3bda2-928b-45a7-b44f-21e12ec84b8a
+
+</p>
+
+### 🚀 Key Updates
+1. Multi-Concurrency Support
+   - Added capability to handle multiple concurrent inference requests. Supports receiving and executing multiple tasks simultaneously.
+   - We implemented [custom_flashinfer](https://github.com/kvcache-ai/custom_flashinfer/tree/fix-precision-mla-merge-main) based on the high-performance and highly flexible operator library [flashinfer](https://github.com/flashinfer-ai/flashinfer/), and achieved a variable batch size CUDA Graph, which further enhances flexibility while reducing memory and padding overhead.
+   - In our benchmarks, overall throughput improved by approximately 130% under 4-way concurrency.
+   - With support from Intel, we tested KTransformers v0.2.4 on the latest Xeon6 + MRDIMM-8800 platform. By increasing concurrency, the total output throughput increased from 17 tokens/s to 40 tokens/s. We observed that the bottleneck has now shifted to the GPU. Using a higher-end GPU than the 4090D could further improve performance.
+2. Engine Architecture Optimization
+ ![image](https://github.com/user-attachments/assets/f5f001fa-dca7-4377-a01a-32192902aa47)
+  Inspired by the scheduling framework of sglang, we refactored KTransformers with a clearer three-layer architecture through an update of 11,000 lines of code, now supporting full multi-concurrency:
+   - Server：Handles user requests and serves the OpenAI-compatible API.
+   - Inference Engine：Executes model inference and supports chunked prefill.
+   - Scheduler：Manages task scheduling and requests orchestration. Supports continuous batching by organizing queued requests into batches in a FCFS manner and sending them to the inference engine.
+3. Project Structure Reorganization
+All C/C++ code is now centralized under the /csrc directory.
+4. Parameter Adjustments
+Removed some legacy and deprecated launch parameters for a cleaner configuration experience.
+We plan to provide a complete parameter list and detailed documentation in future releases to facilitate flexible configuration and debugging.
+### 📚 Upgrade Notes
+- Due to parameter changes, users who have installed previous versions are advised to delete the ~/.ktransformers directory and reinitialize.
+- To enable multi-concurrency, please refer to the latest documentation for configuration examples.

Note that the directory should only contains GGUF of current model, which means you need one separate directory for each model.
-
 - `--optimize_config_path` (required except for Qwen2Moe and DeepSeek-V2): Path of YAML file containing optimize rules. There are two rule files pre-written in the [ktransformers/optimize/optimize_rules](ktransformers/optimize/optimize_rules) directory for optimizing DeepSeek-V2 and Qwen2-57B-A14, two SOTA MoE models.
-
 - `--max_new_tokens`: Int (default=1000). Maximum number of new tokens to generate.
-
 - `--cpu_infer`: Int (default=10). The number of CPUs used for inference. Should ideally be set to the (total number of cores - 2).
 
+<h3>Start Server</h3>
+We provide a server script, which supports multi-concurrency functionality in version v0.2.4.
+
+```
+python ktransformers/server/main.py --model_path /mnt/data/models/DeepSeek-V3 --gguf_path /mnt/data/models/DeepSeek-V3-GGUF/DeepSeek-V3-Q4_K_M/ --cpu_infer 62 --optimize_config_path ktransformers/optimize/optimize_rules/DeepSeek-V3-Chat-serve.yaml --port 10002 --chunk_size 256 --max_new_tokens 1024 --max_batch_size 4 --port 10002 --cache_lens 32768 --backend_type balance_serve
+```
+It features the following arguments:
+
+- `--chunk_size`: Maximum number of tokens processed in a single run by the engine.
+- `--cache_lens`: Total length of kvcache allocated by the scheduler. All requests share a kvcache space corresponding to 32768 tokens, and the space occupied will be released after the requests are completed.
+- `--backend_type`: `balance_serve` is a multi-concurrency backend engine introduced in version v0.2.4. The original single-concurrency engine is `ktransformers`.
+- `--max_batch_size`: Maximum number of requests (prefill + decode) processed in a single run by the engine. (Supported only by `balance_serve`)

 *从我们对 DeepSeekV2、DeepSeekV3 和 DeepSeekR1 的研究中，当我们略微减少推理中的激活专家数量时，输出质量没有变化。但解码和预填充的速度加快了，这令人鼓舞。因此，我们的展示利用了这一发现。*

 ## 一些解释
-1. 我们还想进一步利用 Xeon Gold CPU 上的两个 NUMA 节点。为了避免节点之间的数据传输成本，我们在两个节点上 "copy" 了关键矩阵，这会增加内存占用，但会加速预填充和解码过程。但这种方法占用大量内存，加载权重时速度较慢，因此加载时请耐心等待并监控内存使用情况。我们计划优化这一巨大的内存开销。敬请期待。

 2. 命令参数 `--cpu_infer 65` 指定使用多少核心（超过物理核心数量是可以的，但并不是越多越好。根据实际核心数量适当降低此值）。<br>
-
 3. 为什么使用 CPU/GPU 混合推理？
-DeepSeek 的 MLA 操作符计算密集。虽然全部在 CPU 上运行是可行的，但将繁重的计算任务卸载到 GPU 上能带来巨大的性能提升。

 4. 加速来自哪里？
 
    - 专家卸载：与传统的基于层或 KVCache 卸载（如 llama.cpp 中的）不同，我们将专家计算卸载到 CPU，将 MLA/KVCache 卸载到 GPU，与 DeepSeek 的架构完美对齐，实现最佳效率。
-   - 英特尔 AMX 优化 – 我们的 AMX 加速内核经过精心调优，运行速度是现有 llama.cpp 实现的数倍。我们计划在清理后开源此内核，并考虑向 llama.cpp 上游贡献代码。

-英特尔目前是唯一支持 AMX 类似指令的 CPU 供应商，与仅支持 AVX 的替代方案相比，性能显著更好。

 ## 常见问题解答
+
 ### R1 不返回思考过程
+
 注意！如果测试 R1 可能会跳过思考。因此，可以添加参数：`--force_think true`。详细信息在 [常见问题解答](./FAQ.md) 部分中。 <br>
 
 ## 问题
+
 * 修复服务器集成功能以实现网络API访问支持
 * 修复本地聊天功能仅支持单行提示输入的问题（目前输入换行符(\n)即开始生成提示）
