Work History

April 2026

4 Commits • 2 Features

Apr 1, 2026

Month: 2026-04. Focused on performance-oriented GPU kernel improvements in ROCm/AMDMIGraphX through JIT compilation and vectorization. Delivered multiple JIT implementations replacing legacy device code for critical ops (multinomial, RNN with variable sequence lengths, nonzero, and prefix_scan_sum) and reintroduced GPU fused argmin/argmax vectorization to boost reduction throughput. These efforts advance the device-to-JIT migration and position AMDMIGraphX for higher throughput and lower latency on workloads with variable sequence lengths and large reductions.

March 2026 performance and delivery summary for ROCm/AMDMIGraphX: Delivered JIT-enabled improvements across core operators to accelerate inference and simplify maintenance. Key work includes Argmin/Argmax support as JIT-based reduce ops with legacy cleanup, a new JIT path for the fill operation to improve GPU throughput, and JIT compilation with kernel fusion for logsoftmax and reverse. These changes reduce execution latency, improve fusion opportunities, and shorten the maintenance surface by removing legacy code, aligning with performance and reliability goals.

Jan 1, 2026

Month: 2026-01 — ROCm/AMDMIGraphX monthly summary focusing on business value and technical achievements. Delivered two key enhancements: (1) Flash decoding optimization for attention fusion enabling automatic splitting and padding of long key-value sequences to boost performance; (2) Skip macro for test framework to improve test reporting and organization. No major bugs fixed this month. Impact: improved long-sequence inference throughput, clearer CI/test results, and improved maintainability. Technologies demonstrated: C++, GPU-accelerated optimization, macro-based test framework extension, issue tracking with AIMIGRAPHX-289/341/467.

Monthly summary for 2025-11: Key work on ROCm/AMDMIGraphX focusing on graph execution robustness and attention mechanism enhancements. Delivered external inputs hoisting, FP32 GEMM compatibility gating for Navi GPUs, and a refactor of topological sorting to boost graph execution efficiency. Added flash decoding with split KV and Grouped Query Attention (GQA), updated attention fusion to support multiple splits, introduced new environment variables and tests, and performed a clarifying reorder of attention struct members. These changes improve GPU compatibility, performance, and maintainability, delivering tangible business value by enabling broader hardware support, higher throughput, and more robust attention paths.

Monthly summary for 2025-10 focusing on features delivered, major fixes, impact, and skills demonstrated across ROCm repos. Key features delivered this month: - GEMM-GEMM Fusion with rocMLIR Integration in ROCm/AMDMIGraphX: introduced a new GEMM+GEMM fusion pattern with an intervening element-wise op, integrated with rocMLIR. Added a new environment variable to control the fusion and introduced tests to validate correctness and stability. (Commit: b3b6dfdc2a6d1ea5f3c15ebe59d938ec41b9363c) - G+G operation problem configurations for tier 1 models in ROCm/rocMLIR: expanded problem configurations including data types, transpositions, and matrix dimensions for fp32 and fp16 variants, broadening performance testing and profiling capabilities. (Commit: 3c54e6bffb3f1a6becf0c2e93847f110ecb74072) Major bugs fixed: - No major bugs fixed reported in this period. Focus remained on feature delivery, test coverage, and validation of new capabilities. Overall impact and accomplishments: - Enhanced kernel fusion opportunities and now capable of combining GEMM-like operations more efficiently, potentially improving throughput and reducing memory bandwidth in end-to-end workloads. - Broadened performance testing and profiling coverage for g+g patterns, enabling better benchmarking for tier1 workloads and faster identification of regression risks. - Strengthened the ROCm stack alignment by delivering end-to-end feature implementations with tests and documentation-ready commits. Technologies/skills demonstrated: - rocMLIR integration and feature flagging via environment variables - GEMM fusion pattern design and testing, along with coverage for element-wise fusion scenarios - FP32/FP16 data type configurations and tier1 model profiling for performance evaluation - Test-driven validation and commit-oriented development across ROCm/Kernels.

Aug 1, 2025

August 2025 — ROCm/AMDMIGraphX: two key feature improvements focused on installation experience and build reliability. Key outcomes: - SLES Installation Prerequisites Simplification: Removed the perl-File-BaseDir dependency from the SLES prerequisites script, reducing install footprint and ensuring only the required dependencies are installed for SLES. - ROCm 7.0 Build Compatibility Enhancements: Added warning suppression for -Wno-switch-default in CMake and implemented a check for deprecated declarations in system headers when using Clang with a specific GCC installation directory, improving build reliability and cross-distro compatibility. Impact and value: - Smoother SLES onboarding and fewer install-time issues, contributing to faster deployments and reduced support overhead. - More robust ROCm 7.0 builds with fewer false-positive warnings and better compatibility across environments. Technologies demonstrated: - CMake configuration tuning, compiler diagnostics handling, build-system hygiene, and cross-distro compatibility between Clang and GCC. - Dependency management optimization and targeted build-time checks to improve reliability.
