Abstract

The problem of scheduling a set of partially ordered tasks on a nonpreemptive multiprocessor system of identical processors assuming that the execution time of some tasks can vary within a set of known values is studied in an effort to construct a more realistic static schedule.

A new heuristic algorithm (CP/MISF/TD) based on task duplication is proposed. The effectiveness of the algorithm is proved by comparing the results obtained for a wide variety of task graphs with the ones obtained by applying the classical list scheduling algorithms which consider fixed time tasks.

Keywords: Static scheduling, List scheduling, Heuristic algorithms, Task duplication, Multiprocessor systems.

In traditional precedence-constrained scheduling a task is ready to execute when all its predecessors are complete. We call such a task an AND task. In this paper we allow certain tasks to be ready when just one of their predecessors is complete. ...
