September 2025 monthly summary for NVIDIA/spark-rapids-jni focusing on delivering observability enhancements and cross-thread memory diagnostics to accelerate debugging and reliability of GPU-accelerated Spark workloads.

April 2025: Delivered an API-based lifecycle control enhancement for NvtxRange in bdice/cudf, replacing the previous RAII pattern with static push/pop methods to support an explicit apply-pattern lifecycle in plugins. This change provides clearer lifecycle management, easier plugin integration, and lays the groundwork for future instrumentation improvements.

November 2024 monthly summary for NVIDIA/spark-rapids-jni: Delivered global GPU memory allocation tracking in Spark Resource Adaptor, enabling accurate memory usage reporting across threads and improving resource planning for GPU workloads. This release focuses on cross-thread memory visibility and establishes groundwork for enhanced tuning and capacity planning.

October 2024: Delivered a focused stability improvement for NVIDIA/spark-rapids-jni by fixing GPU memory deallocation tracking in the Spark Resource Adaptor. The patch ensures accurate accounting of GPU memory allocations and deallocations, addressing a max bytes deallocation edge-case, and strengthening reliability of GPU-accelerated Spark workloads. This work reduces memory leakage risk and improves resource scheduling and predictability for production jobs.
