Developed per-workload memory management enhancements in the yuwata/systemd repository by introducing the MemoryTHP= unit file setting, enabling Transparent Huge Pages (THP) to be configured for individual workloads. Leveraging C programming and Linux kernel development expertise, implemented a prctl-based policy override to allow systemd-run to disable THP for specific processes, supporting targeted performance tuning without altering global system policies. Automated unit tests were added using Bash scripting to validate correct THP behavior across various execution paths, ensuring reliability and correctness. This work addressed the need for granular memory management, improving predictability and scalability for memory-intensive workloads in complex environments.
