During March 2026, Geng focused on stabilizing GPU memory management for the apache/sedona-db repository by upgrading RAPIDS RMM to version 25.12 and developing a patch to address a race condition. Working primarily with C++ and CMake, Geng applied expertise in GPU programming and memory management to reduce memory-related errors during high-load spatial computations. This targeted bug fix improved the reliability and throughput of GPU-accelerated operations in production environments. Although the work centered on a single bug rather than new features, it demonstrated depth in diagnosing and resolving complex concurrency issues within critical infrastructure for spatial data processing.
