# NKI Autotune - Scoreboard (trn2)

## Overview

This scoreboard tracks optimal loop orders and tiling configurations for the following GEMM modes:
* **LHS × RHS** - Standard matrix multiplication
* **LHS_T × RHS** - Transposed left-hand side matrix multiplication

All shapes are square matrices of the form (M, K, N). The results show the best-performing configurations discovered through autotuning, including loop iteration order and tile sizes per block dimension.
