Developed Metax Backend (MACA) support for the FlagTree/flagtree repository, enabling the platform to build and test on Metax hardware. This work involved creating new build workflows and configuring CMake to accommodate backend-specific requirements, as well as implementing compiler and driver integrations tailored for the Metax environment. Leveraging expertise in C++, GPU programming, and CI/CD, the developer ensured seamless integration and thorough documentation of the new backend within the codebase. By expanding hardware compatibility, this contribution accelerates hardware-targeted testing and deployment for FlagTree, enhancing its flexibility and scalability across diverse environments without introducing any bug fixes during the period.
