During February 2025, Bertoni authored the HBM User Guide section for the argonne-lcf/user-guides repository, focusing on High Bandwidth Memory usage for Aurora Sapphire Rapids CPUs. The work provided detailed, example-driven documentation on configuring HBM, viewing memory node information with Linux tools like numactl, and allocating memory using both memkind and numactl flags. By integrating technical writing with expertise in HPC memory architectures and memory management, Bertoni’s contribution improved onboarding and reduced support needs for users. The documentation, version-controlled in Markdown, offered actionable guidance that addressed real-world HPC workflows, demonstrating depth in both subject matter and technical communication.
