During July 2025, 77@diazepam.cc updated the install_cp2k_toolchain.sh script in the cp2k/cp2k repository to improve GPU architecture support documentation. Focusing on build system configuration and shell scripting, they revised the guidance for the --gpu-ver option to accurately reflect support for A100, H100, and A40 GPUs. This work involved aligning in-script comments with the toolchain’s actual capabilities, reducing the risk of user misconfiguration. By clarifying documentation and ensuring consistency between code and guidance, they enhanced onboarding for new contributors and improved maintainability. The contribution was documentation-focused, with no major bug fixes or new features beyond these updates.
