A Reference Architectural Pattern: Component-Based Scheduling System for Heterogeneous Computing Environment

The paper presents a conceptual design pattern for a component-based scheduling framework for several classes of multi-component applications. In addition, we propose an object oriented reference architecture, which guides the design of a general purpose scheduling system inside a wide-area heterogeneous computing environment or meta-systems. The heterogeneity nature of today´s application and computing environment, make this a challenging problem. However, the current off-the-shelf scheduling software can hardly cope with the rapid innovation in distributed computing applications frameworks, and therefore, the need for an adequate scheduling system with diversified features, and capability for robustness and optimal scheduling efficiency. The design goal is based on the assumption that effective scheduling of multi-component applications is possible, if only sufficient application and system resource cost information would be provided to the scheduler prior to scheduling processes.
