Dynamic-level scheduling for heterogeneous processor networks

Dynamic-level scheduling is an effective compile-time scheduling technique which accounts for interprocessor communication overhead when mapping precedence-constrained, communicating tasks onto arbitrarily interconnected processor networks. Scheduling and routing are performed simultaneously to account for limited interconnections between processors, and communications are scheduled along with computations to eliminate shared-resource contention. The paper extends the dynamic-level scheduling methodology to encompass heterogeneous processing environments, and presents two techniques designed to enhance scheduling performance: forward/backward scheduling, and precedence constraint appendage.<
