Worked on improving the reliability of the Cache Manager in the sgl-project/mini-sglang repository, focusing on backend development and memory management using Python. Addressed a bug in the eviction logic that previously allowed page overlaps and potential memory corruption when handling allocations with page sizes greater than one. Enhanced the allocation process to ensure correct page alignment and prevent overlaps, reducing the risk of allocation failures under high memory pressure. Developed a comprehensive test suite to validate Cache Manager behavior across multiple scenarios, emphasizing robust testing practices. This work strengthened the caching subsystem’s reliability and maintainability in demanding backend environments.
