Dragica Stoiljkovic
During six months on the tenstorrent/tt-metal repository, Dusan Stoiljkovic engineered advanced pooling and convolution features for deep learning workloads, focusing on adaptive and 3D pooling, dynamic kernel sizing, and performance optimizations. He implemented avg_pool2d and adaptive pooling with configurable parameters, enabling flexible model architectures and precise output control. His work included refactoring kernel interfaces, improving memory management, and aligning pooling operations with PyTorch validation. Using C++, Python, and GPU programming, Dusan addressed edge cases, enhanced test infrastructure, and improved CI reliability. The depth of his contributions strengthened model correctness, maintainability, and performance for both research and production deployments.

Mar 1, 2025March 2025 monthly summary for tenstorrent/tt-metal focused on stabilizing and accelerating core Conv2d/Conv3d/Pool workloads through circular buffer indexing improvements. Implemented dynamic, sequential assignment of circular buffer indices across Conv2d/Conv3d/Pool program factories, reducing warnings, improving dispatch performance, and enhancing maintainability. Introduced common utilities for Conv2d program factories, refactoring to improve linting, and ensured buffers are contiguous where beneficial. Adjusted kernel interfaces to pass index values as compile-time arguments where needed to ensure synchronization and avoid hangs, yielding more predictable runtimes. Completed targeted clang-tidy fixes and include hygiene to reduce build noise and improve CI reliability.
