PROFILE

Alexandra Sidorova

Andrey Sidorov contributed to several compiler and backend projects, building features and improving reliability across swiftlang/llvm-project, iree-org/iree, and ROCm/TheRock. He enhanced MLIR TBLGen by adding compound assignment operators for BitEnum types, improving code safety and maintainability using C++ and bit manipulation. In iree-org/iree, he optimized backward convolution lowering for Torch-MLIR by directly targeting the linalg dialect, reducing redundant operations and memory usage. On ROCm/TheRock, he integrated the hipBLASLt plugin for hipDNN through modular CMake-based development, enabling accelerated ML workloads. His work demonstrated depth in compiler design, plugin development, and performance optimization across complex codebases.

Feb 1, 2026

February 2026 monthly performance summary for ROCm/TheRock. Delivered a performance-focused integration of hipBLASLt with hipDNN through a modular plugin/provider architecture, enabling accelerated operations for HIP-based workloads within TheRock. Implemented with a dedicated hipblaslt_plugin project that cleanly decouples provider logic from core TheRock codebase, reducing maintenance risk and enabling independent testing.

Concise monthly summary for 2026-01 highlighting business value and technical achievements across ROCm/rocm-systems and ROCm/TheRock. Delivered improvements focus on build reliability, compatibility, and up-to-date subproject integration. Overall theme: stabilize cross-compiler builds, ensure proper streaming output, and keep rocm-systems aligned with the latest release to reduce integration risk and enable faster adoption of fixes and features.

December 2025 delivered a performance-focused enhancement for backward convolution by directly lowering torch.aten.convolution_backward to the linalg dialect, removing decomposition to the torch dialect and mapping reduction and parallel dimensions directly. This reduces redundant operations and improves the efficiency of the backward pass, aligning with Torch-MLIR integration goals.

September 2025: Delivered a high-value feature in swiftlang/llvm-project's MLIR TBLGen tool by adding compound assignment operators for BitEnum types (|=, &=, ^=). This enables more concise and expressive bitwise operations, and replaces selected arithmetic operators in targeted transformations to improve safety and readability. The work includes documentation updates and is captured in commit acb826e64e773f65ae58eaa98bc8bbb7d07af8d9, linked to PR #160840. There were no major bug fixes recorded in this scope. Overall impact: improved maintainability, reduced boilerplate, and safer transformations in MLIR tooling. Technologies demonstrated: MLIR, TBLGen, BitEnum, LLVM tooling, documentation, and PR-driven development.
