If you mean superlinear speedup there is an obvious explanation for this, your parallel algorithm is smarter than the serial algorithm being used. Note however that is often not the case and some cache etc. explanation might be more valid. Thanks, -- Eray Ozkural (exa) <erayo at cs.bilkent.edu.tr> Comp. Sci.
