Context
The SGEMM Optimization project needed a structured approach to implement five progressive kernel optimizations while building supporting infrastructure for testing, benchmarking, and documentation.
Goals / Non-Goals
Goals
- Deliver five kernel implementations with progressive optimization
- Build comprehensive test coverage
- Establish CI/CD automation
- Create bilingual documentation
Non-Goals
- Production deployment
- Performance optimization beyond Tensor Core
- Multi-GPU support
Decisions
Seven-Phase Implementation
| Phase | Focus | Status |
|---|---|---|
| 1 | Project Infrastructure | ✅ Complete |
| 2 | Kernel Implementation (5 kernels) | ✅ Complete |
| 3 | Utility Infrastructure | ✅ Complete |
| 4 | Testing Suite | ✅ Complete |
| 5 | Build System & CI/CD | ✅ Complete |
| 6 | Documentation | ✅ Complete |
| 7 | Code Quality & Refinement | ✅ Complete |
Kernel Development Sequence
- Naive - Baseline triple-loop implementation
- Tiled - Shared memory blocking
- Bank-Free - Bank conflict elimination
- Double-Buffer - Compute/memory overlap
- Tensor Core - WMMA API acceleration
Version Milestones
| Version | Milestone |
|---|---|
| 1.0.0 | Project Initialization |
| 2.0.0-rc.1 | Memory Leak Fixes (RAII) |
| 2.0.0-rc.2 | GitHub Pages |
| 2.0.0 | Stable Release |
| 2.1.0 | Documentation & Code Cleanup |
Risks / Trade-offs
| Risk | Mitigation |
|---|---|
| Scope creep with additional optimizations | Defined clear 5-kernel scope |
| Documentation falling behind | Dedicated Phase 6 for documentation |
| Code quality issues | Phase 7 for RAII refactoring and dead code cleanup |
