Published on February 26, 2026, the diary describes iterative optimization of a CUDA matrix multiplication kernel and decisions made while seeking performance close to cuBLAS.
Published on February 26, 2026, the diary follows iterative optimization of a CUDA matrix multiplication kernel, a common operation on GPUs. Its goal is to understand how to approach cuBLAS performance, not to create a replacement for that library.
The text presents concrete kernel optimization decisions, but the available summary gives no metrics or numerical results. To consult and verify the details, read the original diary and check which changes it tested and how it compared performance.
