March 2025 – Mirage project monthly performance summary: Delivered key numerical and compiler-level improvements that enhance reliability, performance, and deployment flexibility. Key features include dynamic compute type selection in the GEMM kernel and memory planning enhancements for pipelined inputs (Hopper). Major bugs fixed encompass data type conversion issues in the element_unary kernel and zero-value handling in matrix multiplication, along with corrected tensor overlap calculations in the transpiler. Also cleaned up the qwen_mlp.py demo script to improve usability. Overall impact: improved numerical correctness, memory efficiency, and runtime adaptability, reducing production risk and enabling broader data types and larger pipelines. Technologies/skills demonstrated: kernel-level debugging and optimization, memory management and transpiler refactoring, dynamic type handling, and script maintenance.
