Duncan worked on enhancing the SYCL-Polaris documentation within the argonne-lcf/user-guides repository, focusing on branding alignment and improving developer support accessibility. He systematically renamed all references from 'oneMKL' to 'oneMath' across tables, section headers, code examples, and compilation instructions, ensuring consistency throughout the documentation. Using C++, Markdown, and technical writing skills, Duncan also integrated a direct Codeplay support link to streamline onboarding and reduce user confusion. His work established a foundation for future cross-repository documentation alignment, prioritizing maintainability and clarity. The depth of his contribution lay in the thorough, detail-oriented approach to documentation hygiene and user experience.
