Abstract
A problem that requires I inputs, K outputs and I computations is to be solved on a d -dimensional parallel processing machine (usually d ⩽3). Finite transmission speed and other real-world conditions are assumed. It is proved that the time needed to solve the problem is t =Ω max (I 1d/, K 1d/, T 1(d+1)/). This result is demonstrated for the standard algorithm for multiplying two n ×n matrices
