Over six months, Wrllrw contributed to the PKUHPC/CraneSched repository, focusing on backend reliability, build system maintainability, and security. Wrllrw engineered asynchronous batch processing to improve task throughput and refactored CMake configurations for cleaner dependency management using C++ and CMake. They enhanced system compatibility by introducing libcgroup guards and refined Clang checks, enabling stable EBPF support across diverse Linux environments. Wrllrw also delivered X11 forwarding for remote graphical tasks, improved process management, and strengthened security by refining group ID handling. Their work included targeted bug fixes, robust logging, and code formatting, resulting in a more stable, maintainable, and secure scheduler.

Jun 1, 2025June 2025 monthly summary for PKUHPC/CraneSched: Delivered critical QoS reliability fix and related improvements to QoS path, enhancing scheduling stability and observability. The work focused on fixing an underflow in QoS consumption, adding diagnostics logging, refining the QoS resource device map, and ensuring code style consistency through auto-formatting. These changes reduce risk of QoS-related resource misallocation and improve maintainability.

Apr 1, 2025April 2025 — CraneSched reliability and security hardening. Implemented two critical fixes that stabilize task submission and strengthen process isolation, reducing scheduler submission errors and closing gaps in multi-user permission handling. These changes improve end-to-end job throughput, prevent failing tasks from being submitted, and provide a stronger security posture for worker processes.
