-# XC-LLM: A Specially Optimized LLM Inference Engine for ModelHub XC
+# vLLM-Ascend Multi-LLM Serving Support
 
 ## Overview
 
-The project is optimized based on the popular LLM inference project vLLM. The current version supports Ascend NPU (910B3 & 910B4). 
+This repository is a modified version of [vLLM-Ascend](https://github.com/vllm-project/vllm-ascend) designed to enable multiple large language models (LLMs) to share one Ascend NPU.
 
-One of the key features of this project is efficient memory coordination, enabling multiple vLLM instances share and dynamically hold Ascend NPU's physical memory. When an instance is idle, model parameters are offloaded to host memory. Upon a new inference request, the model parameters are quickly restored to the NPU’s memory (if not exist), without the need to initialize the engine and load the model from scratch. As a result, from the application’s perspective, multiple LLM inference engines can run on the NPU even when their total memory requirements exceed the physical memory limit. This technique is referred to as `InfiniVRAM`.
+The key feature of this project is efficient memory coordination, enabling multiple vLLM instances share and dynamically hold Ascend NPU's physical memory.

+Upon a new inference request, the model parameters are quickly restored to the NPU’s memory (if not exist), without the need to init the engine and load the model from scratch. (For Qwen3-8B, It only causes 0.3s of additional latency to TTFT on a real restore.)

+
+## Features
+
+- **Shared NPU Usage**: Multiple vLLM instances can access the same Ascend NPU, allowing for multi-LLM serving of different LLMs.
+- **Fast Memory Restore**: We decouple the virtual and physical memory allcation. Physical NPU memory is allocated and exported and shared to other LLM engines. LLM engines can restore quickly without reinitialize and memory allocation
 
 
 ## Installation
@@ -25,14 +33,19 @@ docker build -t vllm-ascend-multi-llm:latest -f ./Dockerfile .
 0. To share NPU, processes coordinate via shm, so you need to set all containers with `ipc=host`.
 1. Start a daemon process in a standalone container, by running `vllm_vnpu_daemon` installed inside the image.
 2. Start LLM services with this image, following the official usage instructions.
-3. Due to the limited stream resource of Ascend NPU, you may need to restrict graph capture sizes or disable ACLgraph by setting `--enforce-eager`, especially when launching multiple LLMs. Refer to the [link](https://docs.vllm.ai/projects/ascend/en/latest/faqs.html#how-to-troubleshoot-and-resolve-size-capture-failures-resulting-from-stream-resource-exhaustion-and-what-are-the-underlying-causes).

-### Environment Variables
-- `VNPU_RESERVED_VRAM_SIZE_GB`: The amonut of reserved GPU memory for other miscellaneous memory. Only needs to be set for `vllm_vnpu_daemon`. Try increasing the variable if you launch multiple LLM services and encounter OOM. Default: `8`.
-- `VLLM_VNPU_SHM_NAME`: The name of the shm file. Needs to be set for all containers of the shared vNPU group. Default: `/vllm_acl_vnpu_offload_shm`.
 
 
 ## Limitations
 
-- Restricted by the fact that HCCL cannot be shared, deploying more than one model with multi-GPU (e.g., TP) is not feasible currently.
+- This project only support share a single NPU currently. This is also limited by the fact that HCCL cannot be shared. We haven't figure out how to bypass HCCL. *Help wanted*.
 - The prefix cache will be reset when the LLM is restored, since we just simply discard the KV cache when the LLM is offloaded.
