# Dynamo KVBM
The Dynamo KVBM is a distributed KV-cache block management system designed for scalable LLM inference. It cleanly separates memory management from inference runtimes (vLLM, TensorRT-LLM, and SGLang), enabling GPU↔CPU↔Disk/Remote tiering, asynchronous block offload/onboard, and efficient block reuse.
![A block diagram showing a layered architecture view of Dynamo KV Block manager.](../../docs/images/kvbm-architecture.png)
## Feature Highlights
- **Distributed KV-Cache Management:** Unified GPU↔CPU↔Disk↔Remote tiering for scalable LLM inference.
- **Async Offload & Reuse:** Seamlessly move KV blocks between memory tiers using GDS-accelerated transfers powered by NIXL, without recomputation.
- **Runtime-Agnostic:** Works out-of-the-box with vLLM, TensorRT-LLM, and SGLang via lightweight connectors.
- **Memory-Safe & Modular:** RAII lifecycle and pluggable design for reliability, portability, and backend extensibility.
## Build and Installation
The pip wheel is built through a Docker build process:
```bash
# Build the Docker image with KVBM enabled (from the dynamo repo root)
./container/build.sh --framework none --enable-kvbm --tag local-kvbm
```
Once built, you can either:
**Option 1: Run and use the container directly**
```bash
./container/run.sh --framework none -it
```
**Option 2: Extract the wheel file to your local filesystem**
```bash
# Create a temporary container from the built image
docker create --name temp-kvbm-container local-kvbm:latest
# Copy the KVBM wheel to your current directory
docker cp temp-kvbm-container:/opt/dynamo/wheelhouse/ ./dynamo_wheelhouse
# Clean up the temporary container
docker rm temp-kvbm-container
# Install the wheel locally
pip install ./kvbm*.whl
```
Note that the default pip wheel built is not compatible with CUDA 13 at the moment.
