PROFILE
Márton Bidlek
Marton Bidlek contributed to the ROCm/composable_kernel repository by developing a WMMA-based device_grouped_gemm_fixed_nk implementation for RDNA4 GPUs, replacing the previous XDL kernel to enhance cross-GPU compatibility and testability. He introduced comprehensive unit tests and a generic profiler interface, supporting automated benchmarking and future performance tuning. In a subsequent refactor, Marton improved CK-Builder’s reflection code by removing forward declarations, enabling lazy template evaluation, and modularizing instance trait specializations with dedicated .inc files. His work leveraged advanced C++ development, CUDA, and template metaprogramming, resulting in more maintainable, reliable, and extensible high-performance computing kernels and architectural foundations.

Mar 1, 2026March 2026 monthly summary for ROCm/composable_kernel: Key features delivered: - CK-Builder Reflection Refactor: eliminated forward declarations in device operation templates, enabled lazy template evaluation, and added a dedicated .inc for InstanceTraits specialization to improve maintainability and avoid circular dependencies. Commit: 683865895ea875f6f2d46a9c25fc1b1f99154b07. Major bugs fixed: - Resolved a circular-dependency risk in CK-Builder reflection by removing forward declarations and applying lazy evaluation, reducing undefined symbol errors and build fragility. Overall impact and accomplishments: - Significantly improved maintainability and clarity of CK-Builder reflection code, enabling smoother integration of new device ops and easier future refactors. Verified with existing CK Builder regression tests; no regressions observed. Technologies/skills demonstrated: - Advanced C++ template metaprogramming, lazy template evaluation, modular code organization with .inc files, and regression testing discipline.

Feb 1, 2026February 2026: Delivered the RDNA4 WMMA-based device_grouped_gemm_fixed_nk implementation for ROCm/composable_kernel, replacing the XDL kernel with a WMMA-based path. Added unit tests for both the WMMA and reference XDL implementations and introduced a generic profiler interface to enable automated testing. No major bugs fixed this month; focus was on enabling the RDNA4 path, test coverage, and tooling to support future performance tuning. This work improves cross-GPU compatibility, testability, and reliability of the grouped GEMM feature, strengthens the foundation for performance optimization, and demonstrates proficiency in WMMA, RDNA4, and HIP-based GPU kernels.
