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

### 🚀 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: + ![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.
