Bogdan Petkovic focused on stabilizing RDNA2 compute unit handling in the ROCm/rocMLIR repository, addressing a bug in the architecture database that affected the minimum number of compute units (minNumCU) for gfx103x. Using C++ and MLIR, he fixed the minNumCU modeling and decoupled test dependencies from architecture preset defaults by explicitly pinning compute unit counts in test configurations. This approach improved test reliability and reduced fragility across architecture changes, ensuring more predictable behavior for downstream users. His work enhanced backend stability and test coverage, reflecting a deep understanding of architecture-specific challenges in GPU software development and validation.
