Worked on the cp2k/cp2k repository to enhance the install_cp2k_toolchain.sh script by updating documentation and comments for the --gpu-ver option, ensuring support for current GPU architectures such as A100, H100, and A40. Focused on build system configuration and Shell scripting, the work aligned the script’s documentation with its actual capabilities, reducing the risk of misconfiguration and improving clarity for new contributors. No bug fixes were required during this period, as the primary goal was to improve maintainability and onboarding through accurate, up-to-date guidance, making it easier for users to select the correct GPU version during installation.
