PROFILE

Mouliraj Elamurugan

Over six months, contributed to the tenstorrent/tt-llk and tt-metal repositories by developing and optimizing low-level mathematical and activation functions for deep learning hardware. Work included implementing and accelerating operations such as acosh, asinh, atanh, SiLU, hard sigmoid, and Leaky ReLU, as well as device-accelerated cbrt and sinh, using C++ and Python. Enhanced performance through kernel-level optimizations and hardware-specific instructions, achieving measurable speedups and improved inference throughput. Addressed robustness by refining error handling, input validation, and rounding logic, while expanding data-type support for SFPU operations. Emphasized test-driven development, CI validation, and maintainable software architecture throughout all contributions.

Month: 2025-10. Summary: In October 2025, delivered a targeted performance optimization for tenstorrent/tt-llk by implementing Leaky ReLU via Tensor Transfer Instructions (TTI). Replaced the previous activation path with TTI-based computation, delivering ~8% speedup on small tile workloads and ~3% on larger tensor operations. This work is tracked in commit 58e4e4fdb77d836e1013b7df6759705a7c9753f2 with message 'Optimize leaky relu (#712)'. Major bugs fixed: none reported this month. Overall impact: improved inference throughput and lower latency for activation-heavy workloads; demonstrates strong low-level optimization capability and careful performance measurement. Technologies demonstrated: Tensor Transfer Instructions, low-level kernel optimization, performance benchmarking, and disciplined change management.
