It is standard practice to submit a PR to update the +PyTorch version as early as possible when a new [PyTorch stable +release](https://github.com/pytorch/pytorch/blob/main/RELEASE.md#release-cadence) becomes available. +This process is non-trivial due to the gap between PyTorch +releases. Using [#16859](https://github.com/vllm-project/vllm/pull/16859) as +an example, this document outlines common steps to achieve this update along with +a list of potential issues and how to address them. + +## Test PyTorch release candidates (RCs) + +Updating PyTorch in vLLM after the official release is not +ideal because any issues discovered at that point can only be resolved +by waiting for the next release or by implementing hacky workarounds in vLLM. +The better solution is to test vLLM with PyTorch release candidates (RC) to ensure +compatibility before each release. + +PyTorch release candidates can be downloaded from PyTorch test index at https://download.pytorch.org/whl/test. +For example, torch2.7.0+cu12.8 RC can be installed using the following command: + +``` +uv pip install torch torchvision torchaudio --index-url https://download.pytorch.org/whl/test/cu128 +``` + +When the final RC is ready for testing, it will be announced to the community +on the [PyTorch dev-discuss forum](https://dev-discuss.pytorch.org/c/release-announcements). +After this announcement, we can begin testing vLLM integration by drafting a pull request +following this 3-step process: + +1. Update requirements files in https://github.com/vllm-project/vllm/tree/main/requirements +to point to the new releases for torch, torchvision, and torchaudio. +2. Use `--extra-index-url https://download.pytorch.org/whl/test/` to +get the final release candidates' wheels. Some common platforms are `cpu`, `cu128`, +and `rocm6.2.4`. +3. As vLLM uses uv, make sure that `unsafe-best-match` strategy is set either +via `UV_INDEX_STRATEGY` env variable or via `--index-strategy unsafe-best-match`. + +If failures are found in the pull request, raise them as issues on vLLM and +cc the PyTorch release team to initiate discussion on how to address them. + +## Update CUDA version + +The PyTorch release matrix includes both stable and experimental [CUDA versions](https://github.com/pytorch/pytorch/blob/main/RELEASE.md#release-compatibility-matrix). Due to limitations, only the latest stable CUDA version (for example, +torch2.7.0+cu12.6) is uploaded to PyPI. However, vLLM may require a different CUDA version, +such as 12.8 for Blackwell support. +This complicates the process as we cannot use the out-of-the-box +`pip install torch torchvision torchaudio` command. The solution is to use +`--extra-index-url` in vLLM's Dockerfiles. + +1. Use `--extra-index-url https://download.pytorch.org/whl/cu128` to install torch+cu128. +2. Other important indexes at the moment include: + 1. CPU ‒ https://download.pytorch.org/whl/cpu + 2. ROCm ‒ https://download.pytorch.org/whl/rocm6.2.4 and https://download.pytorch.org/whl/rocm6.3 + 3. XPU ‒ https://download.pytorch.org/whl/xpu +3. Update .buildkite/release-pipeline.yaml and .buildkite/scripts/upload-wheels.sh to +match the CUDA version from step 1. This makes sure that the release vLLM wheel is tested +on CI. + +## Address long vLLM build time + +When building vLLM with a new PyTorch/CUDA version, no cache will exist +in the vLLM sccache S3 bucket, causing the build job on CI to potentially take more than 5 hours +and timeout. Additionally, since vLLM's fastcheck pipeline runs in read-only mode, +it doesn't populate the cache, so re-running it to warm up the cache +is ineffective. + +While ongoing efforts like [#17419](https://github.com/vllm-project/vllm/issues/17419) +address the long build time at its source, the current workaround is to set VLLM_CI_BRANCH +to a custom branch provided by @khluu (`VLLM_CI_BRANCH=khluu/use_postmerge_q`) +when manually triggering a build on Buildkite. This branch accomplishes two things: + +1. Increase the timeout limit to 10 hours so that the build doesn't timeout. +2. Allow the compiled artifacts to be written to the vLLM sccache S3 bucket +to warm it up so that future builds are faster. + +

+ +

+ +## Update dependencies + +Several vLLM dependencies, such as FlashInfer, also depend on PyTorch and need +to be updated accordingly. Rather than waiting for all of them to publish new +releases (which would take too much time), they can be built from +source to unblock the update process. + +### FlashInfer +Here is how to build and install it from source with torch2.7.0+cu128 in vLLM [Dockerfile](https://github.com/vllm-project/vllm/blob/27bebcd89792d5c4b08af7a65095759526f2f9e1/docker/Dockerfile#L259-L271): + +``` +export TORCH_CUDA_ARCH_LIST='7.5 8.0 8.9 9.0 10.0+PTX' +export FLASHINFER_ENABLE_SM90=1 +uv pip install --system --no-build-isolation "git+https://github.com/flashinfer-ai/flashinfer@v0.2.6.post1" +``` + +One caveat is that building FlashInfer from source adds approximately 30 +minutes to the vLLM build time. Therefore, it's preferable to cache the wheel in a +public location for immediate installation, such as https://download.pytorch.org/whl/cu128/flashinfer/flashinfer_python-0.2.6.post1%2Bcu128torch2.7-cp39-abi3-linux_x86_64.whl. For future releases, contact the PyTorch release +team if you want to get the package published there. + +### xFormers +Similar to FlashInfer, here is how to build and install xFormers from source: + +``` +export TORCH_CUDA_ARCH_LIST='7.0 7.5 8.0 8.9 9.0 10.0+PTX' +MAX_JOBS=16 uv pip install --system --no-build-isolation "git+https://github.com/facebookresearch/xformers@v0.0.30" +``` + +### Mamba + +``` +uv pip install --system --no-build-isolation "git+https://github.com/state-spaces/mamba@v2.2.4" +``` + +### causal-conv1d + +``` +uv pip install 'git+https://github.com/Dao-AILab/causal-conv1d@v1.5.0.post8' +``` + +## Update all the different vLLM platforms + +Rather than attempting to update all vLLM platforms in a single pull request, it's more manageable +to handle some platforms separately. The separation of requirements and Dockerfiles +for different platforms in vLLM CI/CD allows us to selectively choose +which platforms to update. For instance, updating XPU requires the corresponding +release from https://github.com/intel/intel-extension-for-pytorch by Intel. +While https://github.com/vllm-project/vllm/pull/16859 updated vLLM to PyTorch +2.7.0 on CPU, CUDA, and ROCm, https://github.com/vllm-project/vllm/pull/17444 +completed the update for XPU.

The client sends an HTTP request to the Proxy/Router's `/v1/completions` interface. +2. The Proxy/Router selects a **1P1D (1 Prefill instance + 1 Decode instance)** through either through round-robin or random selection, generates a `request_id` (rules to be introduced later), modifies the `max_tokens` in the HTTP request message to **1**, and then forwards the request to the **P instance**. +3.

When the GPU buffer is full, the KV cache is stored in the **local Tensor memory pool**. +6. During the **Decode**, the D instance's main process retrieves the KV cache (transmitted by the P instance) from either the **GPU buffer** or the **memory pool**, thereby **skipping Prefill**. +7.

It maintains a dictionary of `http_addr -> zmq_addr`. The `http_addr` is the IP:PORT for the vLLM instance's request, while the `zmq_addr` is the address for KV cache handshake and metadata reception. + +The Proxy/Router is responsible for selecting 1P1D based on the characteristics of the client request, such as the prompt, and generating a corresponding `request_id`, for example: + +``` +cmpl-___prefill_addr_10.0.1.2:21001___decode_addr_10.0.1.3:22001_93923d63113b4b338973f24d19d4bf11-0 +``` + +Currently, to quickly verify whether xPyD can work, a round-robin selection of 1P1D is used. In the future, it is planned to use a trie combined with the load status of instances to select appropriate P and D. + +Each P/D instance periodically sends a heartbeat packet to the Proxy/Router (currently every 3 seconds) to register (i.e., report `http_addr -> zmq_addr`) and keep the connection alive. If an instance crashes and fails to send a ping for a certain period of time, the Proxy/Router will remove the timed-out instance (this feature has not yet been developed). + +## KV Cache Transfer Methods + +There are three methods for KVcache transfer: PUT, GET, and PUT_ASYNC. These methods can be specified using the `--kv-transfer-config` and `kv_connector_extra_config` parameters, specifically through the `send_type` field. Both PUT and PUT_ASYNC involve the P instance actively sending KVcache to the D instance. The difference is that PUT is a synchronous transfer method that blocks the main process, while PUT_ASYNC is an asynchronous transfer method. PUT_ASYNC uses a dedicated thread for sending KVcache, which means it does not block the main process. In contrast, the GET method involves the P instance saving the KVcache to the memory buffer after computing the prefill. The D instance then actively retrieves the computed KVcache from the P instance once it has allocated space for the KVcache. + +Experimental results have shown that the performance of these methods, from highest to lowest, is as follows: PUT_ASYNC → GET → PUT. + +## P2P Communication via ZMQ & NCCL + +As long as the address of the counterpart is known, point-to-point KV cache transfer (using NCCL) can be performed, without being constrained by rank and world size. To support dynamic scaling (expansion and contraction) of instances with PD disaggregation. This means that adding or removing P/D instances does not require a full system restart. + +Each P/D instance only needs to create a single `P2pNcclEngine` instance. This instance maintains a ZMQ Server, which runs a dedicated thread to listen on the `zmq_addr` address and receive control flow requests from other instances. These requests include requests to establish an NCCL connection and requests to send KVcache metadata (such as tensor shapes and data types). However, it does not actually transmit the KVcache data itself. + +When a P instance and a D instance transmit KVcache for the first time, they need to establish a ZMQ connection and an NCCL group. For subsequent KVcache transmissions, this ZMQ connection and NCCL group are reused. The NCCL group consists of only two ranks, meaning the world size is equal to 2. This design is intended to support dynamic scaling, which means that adding or removing P/D instances does not require a full system restart. As long as the address of the counterpart is known, point-to-point KVcache transmission can be performed, without being restricted by rank or world size. + +## NCCL Group Topology + +Currently, only symmetric TP (Tensor Parallelism) methods are supported for KVcache transmission. Asymmetric TP and PP (Pipeline Parallelism) methods will be supported in the future. Figure 2 illustrates the 1P2D setup, where each instance has a TP (Tensor Parallelism) degree of 2. There are a total of 7 NCCL groups: three vLLM instances each have one NCCL group with TP=2. Additionally, the 0th GPU card of the P instance establishes an NCCL group with the 0th GPU card of each D instance. Similarly, the 1st GPU card of the P instance establishes an NCCL group with the 1st GPU card of each D instance. + +![image2](https://github.com/user-attachments/assets/837e61d6-365e-4cbf-8640-6dd7ab295b36) + +Each NCCL group occupies a certain amount of GPU memory buffer for communication, the size of which is primarily influenced by the `NCCL_MAX_NCHANNELS` environment variable. When `NCCL_MAX_NCHANNELS=16`, an NCCL group typically occupies 100MB, while when `NCCL_MAX_NCHANNELS=8`, it usually takes up 52MB. For large-scale xPyD configurations—such as DeepSeek's 96P144D—this implementation is currently not feasible. Moving forward, we are considering using RDMA for point-to-point communication and are also keeping an eye on UCCL. + +## GPU Memory Buffer and Tensor Memory Pool + +The trade-off in the size of the memory buffer is as follows: For P instances, the memory buffer is not required in PUT and PUT_ASYNC modes, but it is necessary in GET mode. For D instances, a memory buffer is needed in all three modes. The memory buffer for D instances should not be too large. Similarly, for P instances in GET mode, the memory buffer should also not be too large. The memory buffer of D instances is used to temporarily store KVcache sent by P instances. If it is too large, it will reduce the KVcache space available for normal inference by D instances, thereby decreasing the inference batch size and ultimately leading to a reduction in output throughput. The size of the memory buffer is configured by the parameter `kv_buffer_size`, measured in bytes, and is typically set to 5%～10% of the memory size. + +If the `--max-num-seqs` parameter for P instances is set to a large value, due to the large batch size, P instances will generate a large amount of KVcache simultaneously. This may exceed the capacity of the memory buffer of D instances, resulting in KVcache loss. Once KVcache is lost, D instances need to recompute Prefill, which is equivalent to performing Prefill twice. Consequently, the time-to-first-token (TTFT) will significantly increase, leading to degraded performance. + +To address the above issues, I have designed and developed a local Tensor memory pool for storing KVcache, inspired by the buddy system used in Linux memory modules. Since the memory is sufficiently large, typically in the TB range on servers, there is no need to consider prefix caching or using block-based designs to reuse memory, thereby saving space. When the memory buffer is insufficient, KVcache can be directly stored in the Tensor memory pool, and D instances can subsequently retrieve KVcache from it. The read and write speed is that of PCIe, with PCIe 4.0 having a speed of approximately 21 GB/s, which is usually faster than the Prefill speed. Otherwise, solutions like Mooncake and lmcache would not be necessary. The Tensor memory pool acts as a flood diversion area, typically unused except during sudden traffic surges. In the worst-case scenario, my solution performs no worse than the normal situation with a Cache store. + +# Install vLLM + +```shell +# Enter the home directory or your working directory. +cd /home + +# Download the installation package, and I will update the commit-id in time.

If it is too large, the kvcache available for inference will be reduced, leading to a smaller batch size and decreased throughput. +- For Prefill instances, when using non-GET mode, the `kv_buffer_size` can be set to 1, as Prefill currently does not need to receive kvcache.
