PROFILE
Matthew Schilling
Worked extensively on the intel/pti-gpu repository, delivering robust profiling and tracing tools for GPU workloads across Windows and Linux. Focused on stability, cross-platform compatibility, and release readiness, the work included modernizing build systems with CMake, enhancing CI/CD pipelines, and integrating new SYCL and Level Zero APIs. Leveraged C++ and Python to implement features such as graph-based execution, kernel launch support, and detailed versioning metadata, while addressing race conditions, memory management, and test reliability. Improvements in code quality, static analysis, and packaging streamlined developer workflows, reduced integration risk, and enabled smoother adoption of evolving GPU and compiler toolchains.

May 1, 2026May 2026 performance summary for intel/pti-gpu: Focused on stability, metadata, and traceability improvements in the PTI tooling stack. Delivered two key updates: (1) Versioning and Metadata Improvements for PTI, enhancing the VERSIONINFO resource, metadata accessibility via winver.h, and robustness by preserving the original file for automated scripts. (2) SYCL Runtime Initialization Bug Fix and API Traceability Enhancement, initializing the runtime record to zero and propagating XPTI return values to PTI for better API traceability. These changes improve reliability, automation readiness, and end-to-end observability, reducing deployment risk and debugging time, and delivering tangible business value for profiling workflows.

Jan 1, 2026January 2026 highlights for intel/pti-gpu: Cross-platform stability, API evolution, and code quality improvements that shorten feedback loops and enable broader SYCL runtime adoption. Key features delivered include the Intel LLVM SYCL Runtime API expansion with a new kernel-launch API and regenerated API IDs to support upcoming defaults in kernel launches. Major bug fixes stabilized CI and platform compatibility across Linux distributions and Windows, reducing disruption from flaky tests and build regressions. PTI Metrics Library received a set of quality improvements, strengthening correctness and maintainability through C99 compliance, line-ending normalization, removal of redundant copies, overflow safeguards, and a refactor of Level Zero driver initialization. Overall, these changes improve developer velocity, reliability of nightly builds, and readiness for enterprise-scale usage. Business value and technical impact: lower CI downtime, faster iterations on features, smoother cross-platform acceptance of new APIs, and a stronger, more maintainable metrics stack."
