Abstract

The authors present a compile-time scheduling heuristic called dynamic level scheduling,which accounts for interprocessor communication overhead when mappingprecedence-constrained, communicating tasks onto heterogeneous processorarchitectures with limited or possibly irregular interconnection structures. This techniqueuses dynamically-changing priorities to match tasks with processors at each step, andschedules over both spatial and temporal dimensions to eliminate shared resourcecontention. This method is fast, flexible, widely targetable, and displays promisingperformance.
