WebIt is easy to see that this is essentially optimal, for a 1D blocked layout on a bus or ring, because the matrix multiplication formula we use requires every product A(i)*B(i,j) to eventually accumulate on processor j, which entails some data of size n*(n/p) moving from each processor i to each processor j, and this requires at least p-1 messages of size n^2/p. Web23 nov. 2024 · In this way, researchers have discovered new algorithms that multiply n-by-n matrices using fewer than the standard n 3 multiplication steps for many small matrix sizes. But algorithms that outperform not only the standard but also Strassen’s algorithm for small matrices have remained out of reach — until now.
