PROFILE
Julia Fedorova
Julia Fedorova developed and maintained core GPU performance tracing and profiling features for the intel/pti-gpu repository, focusing on robust test automation, CI/CD reliability, and low-level system integration. She engineered callback APIs and enhanced tracing infrastructure using C++ and Python, enabling accurate kernel timing and cross-domain event analysis. Julia refactored build systems with CMake, improved error handling, and optimized device tracing to reduce overhead and improve diagnostics. Her work addressed complex multi-subscriber scenarios, stabilized telemetry, and ensured reliable correlation across SYCL and Level Zero APIs. The depth of her contributions strengthened code maintainability, observability, and performance analysis for production deployments.

Jul 1, 2025July 2025 monthly summary for intel/pti-gpu. Focused on stabilizing GPU performance telemetry in multi-subscriber setups. Major bug fix resolved conflicts with other XPTI subscribers (e.g., unitrace) to prevent incorrect GPU time reporting and to ensure PTI does not subscribe to SYCL runtime events when another subscriber is active. This included detection and communication of foreign subscribers and adjusting initialization to respect existing subscriptions. Result: more reliable GPU time reporting, fewer false positives, and smoother integration with profiling tools across the ecosystem.

Jun 1, 2025June 2025 monthly summary for intel/pti-gpu: Delivered a targeted bug fix to stabilize Unified Runtime include path resolution, reducing build-time misconfigurations and ensuring correct include directory selection across configurations. Implemented via a focused commit that reorders the include search logic to prefer ur_api.h over sycl/ur_api.h in Findunified-runtime.cmake, preventing incorrect include path resolution. This improvement directly reduces downstream compile errors in dependent modules and enhances developer productivity by delivering deterministic builds.
