February 2026 for ROCm/rocm-systems: Delivered a focused bug fix to Rocprofiler instrumentation to enhance profiling accuracy and performance by excluding specific internal libraries from dynamic instrumentation. The change prevents distortion from internal libraries, reduces instrumentation overhead, and improves profiling reliability for developers and performance teams. In addition, refactored internal library handling by renaming _omni_libs to _rocprof_sys_libs to better reflect the scope and updated CHANGELOGs for visibility. Commit 8d7afa53c3a98511e549072d9d9ace3d2efef075 includes the changes and was co-authored by David Galiffi.

January 2026 monthly work summary for ROCm/rocm-systems focusing on reliability, scalability, and developer experience. Delivered a configurable thread limit for ROCm Systems Profiler to prevent segmentation faults at high thread counts, and reinforced build stability across environments by aligning submodule dependencies to resolve libunwind-related issues. Expanded validation and documentation to ensure long-term maintainability and ease of use for profiling at scale.

Performance Review - Monthly Summary for 2025-11 This month delivered a focused set of documentation and compatibility improvements for ROCm-Systems, with an emphasis on cross-version PythonBUILD support and FFmpeg API changes.

June 2025 monthly summary for ROCm/rocprofiler-systems focusing on structure and validation of Roctx API usage within the build/test system. Delivered a C++ Roctx sample and a test harness, plus associated CMake configurations and a test directory to validate Roctx API usage within the existing CI/build flow. Established a baseline for API call verification and regression testing.

May 2025 monthly summary for ROCm/rocprofiler-systems focused on stabilizing data visibility and initialization flow. Reverted PR-154 RCCL initialization changes to restore correct state management and data visibility, addressing VCN data not appearing in Perfetto traces and preventing potential initialization hangs. These improvements enhance profiling reliability and user experience by ensuring consistent data visibility and robust initialization.

April 2025 — ROCm/rocprofiler-systems: Delivered safety-first metrics collection improvements. Implemented a default 'none' CPU sampling and fixed AMD SMI metrics parsing to prevent default collection and to correctly interpret 'all'/'none' values, enhancing reliability and privacy. These changes improve data quality, reduce noise, and lower risk of exposing sensitive metrics for enterprise workloads.
