Over three months, contributed to the halide/Halide repository by developing features focused on GPU scheduling, numerical precision, and developer tooling. Enhanced the IRPrinter to render very small floating-point constants in scientific notation, improving output readability and debugging for numerical computing workflows. Advanced GPU autoscheduling by refactoring the Mullapudi2016 scheduler to efficiently target GPU architectures, and improved HTML visualization with syntax highlighting for Metal and OpenCL code. Delivered robust GPU scheduling logic, including thread safety and tiling strategies, while stabilizing CI tests for IIR blur pipelines. Work utilized C++, JavaScript, and build systems, emphasizing performance optimization and maintainability throughout.
