In this paper, we compare the performances of Cg-based and CUDA-based GPU programming APIs. In particular, their performances on squared matrix multiplications are considered. We also discuss other aspects of these widely-used GPU programming APIs. This work can help gain insight on various applications that involve matrix multiplication that are better suited for a specific GPU programming API.
