Andjela Bogdanovic
In December 2025, Aleksandar Bogdanovic developed scatter operation reduction support in the tenstorrent/tt-mlir repository, enabling reduction semantics such as SUM, PROD, MIN, and MAX within scatter operations. He introduced the scatter_reduce_type attribute to the ttir.scatter and ttir.scatter_in_dim operations, facilitating future integration with TT-Metal reductions. His work included implementing compatibility for bf16 and int32 input tensors, ensuring consistent behavior across data types. Using C++ and MLIR, Aleksandar applied test-driven development and cross-repository collaboration to address TT-MLIR issue #5091. This feature improved model throughput, numerical correctness, and integration readiness for mixed-precision tensor operations in MLIR workflows.

Dec 1, 2025December 2025: Delivered Scatter operation reduction support in the tt-mlir MLIR path, enabling future TT-Metal reduction integration. Introduced a new attribute scatter_reduce_type on ttir.scatter and ttir.scatter_in_dim to support reductions (SUM, PROD, MIN, MAX). Implemented compatibility workarounds for bf16 and int32 input tensors to preserve behavior across data types. This work directly addresses TT-MLIR issue #5091 and aligns with the TT-Metal reduction effort (#31909). Added tests to cover the changes and ensure regression safety. Impact: unlocks reduction semantics in scatter operations, improves model throughput and numerical correctness in mixed-precision scenarios, and strengthens cross-repo integration readiness. Technologies/skills demonstrated: MLIR dialect extension, data-type compatibility handling (bf16/int32), feature flagging via attributes, collaborative cross-repo work, and test-driven development.
