Markus Koskela updated the TensorFlow platform version support documentation in the CSCfi/csc-user-guide repository, ensuring researchers have accurate guidance for deploying TensorFlow versions 2.16, 2.17, and 2.18 across Puhti, Mahti, and LUMI HPC systems. He removed outdated notes about LUMI modules’ experimental status and clarified library dependencies, improving clarity and reducing onboarding friction. Markus applied technical writing and documentation skills using Markdown, focusing on cross-platform compatibility and traceable, versioned release notes. The work maintained repository stability, addressed evolving user needs, and provided a clear, maintainable reference for researchers working with TensorFlow on CSC’s HPC infrastructure.
