PROFILE

Agozillon

Andrew Gozillon contributed to GPU offloading and OpenMP infrastructure across ROCm/aomp, intel/llvm, and swiftlang/llvm-project, focusing on stability, correctness, and test coverage for Fortran and C++ code targeting AMDGPU architectures. He developed and integrated runtime enhancements, smoke tests, and mapping improvements, addressing issues such as device pointer handling, array slicing, and memory management. Using C++, Fortran, and MLIR, Andrew refactored build systems, optimized runtime libraries, and improved CI automation. His work included fixing regressions, aligning dialects with evolving OpenMP standards, and reducing dead code, resulting in more reliable, portable, and maintainable compiler and runtime components for heterogeneous computing.

Mar 1, 2026

March 2026 ROCm/aomp: Focused OpenMP/Fortran test work and stability improvements. Delivered integration of Fortran map tests into the AOMP repo with CI enhancements and configurable GPU architectures, added four new Fortran map tests validating common blocks and data mapping on AMD GPUs, and fixed a rocr 7.2 runtime issue by disabling FP exceptions in UMT. These changes improve test coverage, CI feedback, and upstreamability, delivering tangible business value by enabling faster, reliable validation of features on AMD platforms. Technologies demonstrated include OpenMP, Flang, UMT, ROCm, and CI automation.

Oct 1, 2025

October 2025 delivered significant OpenMP improvements across two LLVM-project forks, enhancing robustness, correctness, and future-proofing for MLIR/OpenMP dialect integration. Key outcomes include Flang OpenMP mapping enhancements to fix negative bounds handling, defer descriptor mapping for assumed dummy arguments to avoid pre-5.2 runtime issues, and refactor map flag representations to MLIR dialect enums for extensibility. ROCm/llvm-project delivered Declare Target mapping and USM enhancements with alignment to OpenMP 6.0 and MLIR/OpenMP dialect updates, plus a fix to attach map flag correctness. In addition, test stabilization around descriptor deferral and code cleanup were completed, reducing flaky tests and improving maintainability. These workstreams collectively improve reliability, performance, and portability of OpenMP offloading across CPU and GPU targets, enabling safer future-ready migrations and stronger performance guarantees.

Sep 1, 2025

Sep 2025 monthly summary: Delivered stability, correctness, and foundational improvements across the LLVM/OpenMP and GPU offloading stacks, spanning intel/llvm, swiftlang/llvm-project, ROCm/llvm-project, and ROCm/aomp. Focused on bug fixes that restore target support, feature work that broadens declare-target capabilities, and CI/test stabilization to reduce flakiness in OpenMP-related workflows. The work strengthened GPU targeting (AMDGPU) support, improved memory and symbol handling for parallel code, and reduced dead code in the runtime, enabling more reliable builds and higher-quality device code generation.

Jan 1, 2025

January 2025 monthly work summary for Xilinx/llvm-aie focusing on OpenMP target support stability and build hygiene. Highlights include OpenMP target lowering/seman­tics improvements across Flang/MLIR with runtime-sized arrays in target regions, stabilization of threadprivate lowering for target operations, and resolution of declare target scope across function boundaries; plus a -werror build cleanup to remove an unused variable in resolve-names.cpp. These efforts improve reliability, portability, and maintainability for OpenMP offloading on AIE devices.
