Preliminary Results of Autotuning GEMM Kernels for the NVIDIA Kepler Architecture – GeForce GTX 680 – LAPACK Working Note 267

Kepler is the newest GPU architecture from NVIDIA, and the GTX 680 is the first commercially available graphics card based on that architecture. Matrix multi-plication is a canonical computational kernel, and often the main target of initial optimization efforts for a new chip. This article presents preliminary results of au-tomatically tuning matrix multiplication kernels for the Kepler architecture using the GTX 680 card.
