Reusing GPU kernels via the Hub
Summary
The Kernel Hub distributes optimised GPU operators as versionable artefacts and loads suitable variants at runtime. This allows specialised kernels to be used without building them into every package. HF Kernels provides pre-built and custom GPU kernels via the Hub.
Ideas
- Kernels can be versioned, evaluated and shipped for hardware variants just like models.
- Choosing at runtime needs a secure binding between operator, device and implementation.
Insights
- Only specialised kernels turn mathematical possibilities into measurable hardware performance.
Facts
- The Python integration loads kernels to match the requested operation.
Critique
- Native code loaded at runtime extends the software supply chain with a particularly privileged component.
Recommendations
- Pin kernel revisions and test numerical correctness and fallbacks on every target GPU.
