Sparse Matrix–Vector Multiplication (SpMV) is an important operation used to accelerate deep learning models on the GPU, but its irregular structure makes it hard to load balance.
This project implements load-balanced SpMV using DirectX12 Work Graphs, letting the GPU schedule work dynamically to achieve better performance despite the irregular nature of the application.

GitHubA KV cache eviction policy for LLM inference that considers both recent attention scores and value vectors when deciding which entries to keep.

GitHubWritten from the ground up to render 3D GLTF Scenes, with a focus on an easy-to-modify rendering pipeline.
Forward++, aka Forward Clustered Rendering, is achieved using a compute shader to determine which lights influence which chunk of the view frustum. This is followed by traditional forward rendering, which calculates lighting only for lights in the same chunk of the view frustum as the surfel. This lets it handle large numbers of lights.
Also includes a voxel renderer with compute shader-based meshing that reduces draw count by 6x.

GitHubA 3D rendering engine capable of drawing massive amounts of geometry efficiently, made possible using per-cluster culling.
Meshes are divided into clusters. A compute shader determines currently visible clusters to minimize the amount of geometry drawn. We are currently working to make this culling use hierarchical z.
Visibility buffer-based rendering is used to save on GPU bandwidth. All triangles are loaded directly from storage buffers, and all vertex attributes are software-interpolated manually in the pixel shader.
There is a complete separation of Geometry, Material, and Lighting passes.
It also includes an automatic asset management system for loading/unloading from disk.
A custom Sparse Array Entity Component System (ECS) implementation is included.
