It supports both synchronous and asynchronous processing, focusing on speed and simplicity. High Performance: Processes millions of … Read more
Abstract:We present a new algorithm RXTX that computes product of matrix by its transpose $XX^{t}$. RXTX uses $5%$ less multiplications and additions than State-of-the-Art and achieves accelerations even for small sizes of matrix $X$. The algorithm was discovered by combining … Read more
