We investigate the maximum flow time minimization problem of on-line scheduling jobs on m identical parallel machines. When preemption is allowed, we derive an optimal algorithm with competitive ratio 2 -1/m. When preemption is not allowed and m = 2, we show that the First In First Out heuristic ach
