Worked on the facebookexperimental/triton repository to expand support for non-power-of-two tensor shapes by developing a modular arithmetic back-end and integrating NPOT-aware primitives throughout the compiler pipeline. Leveraged C++, CUDA, and MLIR to enable general tensor shapes in LinearLayout, wiring NPOT layouts through code generation, conversions, and swizzle for broader hardware compatibility. Enabled f32 redux operations on GB300-class GPUs with correct NaN semantics, improving compute performance for supported hardware. Addressed a warp-specialization crash involving shared SMEM buffers in multi-partition kernels, enhancing reliability for complex attention-like workloads and directly improving model inference throughput and end-user performance.

Jun 1, 2026June 2026 performance summary for Triton development. Expanded non-power-of-two (NPOT) support across the LinearLayout and compiler path, enabling general tensor shapes and more efficient code paths. Delivered a modular arithmetic back-end and NPOT-aware primitives to support NPOT dimensions, and wired NPOT layouts through codegen, conversions, and swizzle for broader hardware compatibility. Enabled f32 redux on GB300-class GPUs (sm_103a) to boost compute performance with correct NaN semantics. Fixed a warp-specialization crash in multi-partition kernels caused by shared SMEM buffers, improving stability for complex attention-like workloads. These workstream outcomes broaden tensor-shaped workloads, unlock hardware-specific performance, and improve reliability, directly enhancing end-user throughput and model inference performance while demonstrating advanced MLIR/LLVM integration and GPU optimization skills.
