For the real divisible load applications

additional information and overlapped partitions are always needed.This paper introduces these factors into the divisible load scheduling model.We revised three efficient-proved schemes:equal allocation

LIFO and FIFO for the extended model

on two platforms the master with or without communication coprocessor.Closed-form solutions for the response time of these schemes are derived.Based on these expressions

we rigorously compared the performance of the three schemes

and proved that FIFO is always the best not as without additional information

independent of the scale or type of the systems.
