Overview + The MatrixOne cuvs package provides a high-performance, GPU-accelerated vector search and clustering infrastructure. It acts as + a bridge between the Go-based database kernel and NVIDIA's cuVS and RAFT libraries. The architecture is designed to solve three + primary challenges: + 1. Impedance Mismatch: Reconciling Go’s concurrent goroutine scheduler with CUDA’s thread-specific resource requirements. + 2. Scalability: Supporting datasets that exceed single-GPU memory (Sharding) or high-concurrency search requirements + (Replicated). + 3. Efficiency: Minimizing CUDA kernel launch overhead via dynamic query batching. + + --- + + 2. Core Component: cuvs_worker_t + The cuvs_worker_t is the foundational engine of the architecture. + + Implementation Details: + * Persistent C++ Thread Pool: Instead of executing CUDA calls directly from CGO (which could be scheduled on any OS thread), + the worker maintains a dedicated pool of long-lived C++ threads. Each thread is pinned to a specific GPU device. + * Job Queuing: Requests from the Go layer are submitted as "Jobs" to an internal thread-safe queue. The worker returns a + std::future, allowing the Go layer to perform other tasks while the GPU processes the request. + * Context Stability: By using dedicated threads, we ensure that CUDA context and RAFT resource handles remain stable and + cached, avoiding the expensive overhead of context creation or handle re-initialization. + + --- + + 3. Distribution Modes + The system supports three distinct modes to leverage multi-GPU hardware: + + A. Single GPU Mode + * Design: The index resides entirely on one device. + * Use Case: Small to medium datasets where latency is the priority. + + B. Replicated Mode (Scaling Throughput) + * Design: The full index is loaded onto multiple GPUs simultaneously. + * Mechanism: The cuvs_worker implements a load-balancing strategy (typically round-robin). Incoming queries are dispatched to + the next available GPU. + * Benefit: Linearly scales the Queries Per Second (QPS) by utilizing the compute power of all available GPUs. + + C. Sharded Mode (Scaling Capacity) + * Design: The dataset is partitioned into $N$ shards across $N$ GPUs. + * Mechanism: + 1. Broadcast: A search request is sent to all GPUs. + 2. Local Search: Each GPU searches its local shard independently using RAFT resources. + 3. Top-K Merge: The worker aggregates the results ($N \times K$ candidates) and performs a final merge-sort (often on the + CPU or via a fast GPU kernel) to return the global top-K. + * Benefit: Enables indexing of massive datasets (e.g., 100M+ vectors) that would not fit in the memory of a single GPU. + + --- + + 4. RAFT Resource Management + The package relies on RAFT (raft::resources) for all CUDA-accelerated operations. + + * Resource Caching: raft::resources objects (containing CUDA streams, cuBLAS handles, and workspace memory) are held within the + cuvs_worker threads. They are created once at Start() and reused for the lifetime of the index. + * Stream-Based Parallelism: Every index operation is executed asynchronously on a RAFT-managed CUDA stream. This allows the + system to overlap data transfers (Host-to-Device) with kernel execution, maximizing hardware utilization. + * Memory Layout: Leveraging raft::mdspan and raft::mdarray ensures that memory is handled in a layout-aware manner + (C-contiguous or Fortran-contiguous), matching the requirements of optimized BLAS and LAPACK kernels. + + --- + + 5. Dynamic Batching: The Throughput Key + In a database environment, queries often arrive one by one from different users. Processing these as individual CUDA kernels is + inefficient due to launch overhead and under-utilization of GPU warps. + + The Dynamic Batching Mechanism: + * Aggregation Window: When multiple search requests arrive at the worker within a small time window (microseconds), the worker + stalls briefly to aggregate them. + * Matrix Consolidation: Individual query vectors are packed into a single large query matrix. + * Consolidated Search: A single cuvs::neighbors::search call is made. GPUs are significantly more efficient at processing one + $64 \times D$ matrix than 64 individual $1 \times D$ vectors. + * Automatic Fulfilling: Once the batch search completes, the worker de-multiplexes the results and fulfills the specific + std::future for each individual Go request. + + --- + + 6.

At MatrixOrigin, we recently faced a significant engineering challenge: **How do we build and search an IVF-Flat index of 50 million 1024-dimensional vectors on a server with only 16 cores and 64GB of RAM?** + +Traditional CPU-based approaches were hitting a wall. Building the index took days, and search latency was inconsistent. By integrating NVIDIA’s **cuVS** and **RAFT** libraries into our architecture, we transformed our performance profile. Here is the step-by-step story of how we did it. + +## The Challenge: The "Giant Index" Problem +Our target was an IVF-Flat index with approximately 8,000 clusters holding 50 million vectors. On a 16-core machine, we encountered three primary bottlenecks: +1. **Clustering Latency**: Standard K-Means was slow and often produced unbalanced clusters, leading to "hotspots" that slowed down search. +2. **Assignment Overhead**: Mapping 50 million vectors to their nearest centroids is computationally expensive. On CPUs, this task competed for resources with data loading and decompression, dragging the process out to 24 hours. +3. **The GPU "Single Query" Trap**: Databases typically process one query at a time. GPUs, however, only show their true strength when processing large batches. + +## Step 1: Solving Clustering with Balanced K-Means +Standard K-Means often results in some clusters having thousands of vectors while others have almost none. In an IVF index, this leads to unpredictable IO and search times. + +We initially implemented our own balanced K-Means, which brought the clustering time down from 30 minutes to 5 minutes. However, by switching to the **cuVS Balanced K-Means algorithm**, we utilized GPU parallelism to its fullest. +* **Result**: Clustering time dropped from **5 minutes to just 5 seconds**. + +## Step 2: Offloading Assignment to Brute-Force GPU Kernels +Once the 8,000 centroids are defined, every one of the 50 million vectors must be assigned to its closest cluster. Doing this on a 16-core CPU is a nightmare of cache misses and thread contention. + +By using the **cuVS Brute-Force index** to "offline" this distance computation to the GPU, we eliminated the CPU bottleneck entirely. +* **Result**: The assignment phase dropped from **24 hours to 30 minutes**. + +## Step 3: The Architecture—`cuvs_worker_t` and Dynamic Batching +To solve the "Single Query" problem, we designed a sophisticated bridge between Go and CUDA: the `cuvs_worker_t`. + +### Dynamic Batching: The Secret Sauce +Instead of launching a new CUDA kernel for every incoming request, our worker implements **Dynamic Batching**. It holds incoming queries for a tiny microsecond window, consolidates them into a single matrix, and executes one large GPU search. +* This maximizes warp utilization and reduces kernel launch overhead. +* **Performance Gain**: Provides a **5x-10x throughput boost** in high-concurrency environments. + +### RAFT Resource Management +We leverage the **RAFT** library to manage long-lived `raft::resources`. By caching CUDA streams and handles within persistent C++ threads, we ensure that our Go-based kernel can interact with the GPU with near-zero resource initialization overhead. + +## Step 4: Staying Within 64GB with Auto-Quantization +50 million 1024D vectors in `float32` require roughly 200GB of space—far exceeding our 64GB RAM limit. To solve this, we implemented **Automatic Type Quantization** directly on the GPU. +* **FP16 (Half Precision)**: Reduces memory by 2x with almost zero recall loss. +* **8-Bit Integer (int8/uint8)**: Uses a learned Scalar Quantizer to compress vectors by 4x. +* Because conversion happens on the GPU, we avoid taxing the CPU and minimize PCIe bus traffic. + +## Summary of Supported Indexes +Our architecture now supports a suite of high-performance indexes: +* **CAGRA**: A hardware-accelerated graph index for state-of-the-art search speed. +* **IVF-Flat**: The workhorse for high-accuracy general-purpose search. +* **IVF-PQ**: For extreme compression of billion-scale datasets. +* **K-Means**: For high-speed data partitioning. + +## Conclusion +By shifting the heavy lifting of clustering, assignment, and quantization to the GPU through cuVS, MatrixOne can now handle massive vector datasets on surprisingly modest hardware. What once took a full day now takes less than an hour, with search latencies that remain low even under heavy load. + +The integration of `cuvs_worker_t` and dynamic batching ensures that we don't just have a "fast index," but a **production-ready database engine** capable of scaling with the needs of modern AI.
