Abstract The finishing time properties of several heuristic algorithms for scheduling $\textit{n}$ independent tasks on $\textit{m}$ nonidentical processors are studied. In particular, for $\textit{m}$ = 2 an $\textit{n}$ log $\textit{n}$ time-bounded algorithm is given which generates a schedule having a finishing time of at most (√5 + 1)/2 of the optimal finishing time. A simplified scheduling problem involving identical processors and restricted task sets is shown to be P-complete. However, the LPT algorithm applied to this problem yields schedules which are near optimal for large $\textit{n}.$
