PROFILE
Stefan Krsmanovic
Stefan Krsmanovic developed and enhanced performance profiling, benchmarking, and data analysis infrastructure for the tenstorrent/tt-metal repository over eight months. He built robust Python and C++ test frameworks to measure and visualize kernel and matrix multiplication performance, introducing per-iteration logging, CSV-based metrics, and profiling zones to improve observability and accelerate optimization. His work included refactoring kernel I/O, optimizing data management, and updating dependencies to support evolving hardware configurations. By automating data collection and analysis, Stefan enabled reliable, repeatable performance testing and cross-device comparisons, resulting in faster feedback cycles and more data-driven optimization across the stack. His contributions demonstrated technical depth.

Jan 1, 2025January 2025 performance summary for tenstorrent/tt-metal focused on strengthening profiling reliability, benchmarking capabilities, and data-driven performance insights across WH and BH configurations. Implemented a safety fix to profiler log deletion to ensure only the log file is removed (avoiding test setup failures). Added per-iteration, CSV-format profiler logs to deepen performance visibility during benchmarking. Extended benchmarking with BH compute grid size support for dynamic hardware scaling. Built warning-free data-analysis scripts to visualize and compare WH and BH results, enabling clearer cross-device optimization. Improved microbenchmark accuracy for matrix multiplication by refining operation counting. These changes reduce flaky tests, accelerate benchmarking cycles, and empower data-informed performance tuning across devices.
