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