A Lightweight Specialized Meta-scheduler for Business-Oriented Applications

摘要

The process of meta-scheduling is a key feature in the architecture of typical computational grids. Many meta-schedulers have reached maturity obstacles that slow down their use. On one hand, some meta-schedulers are tied to an environment requiring users to adopt the whole infrastructure in order to use them. On the other hand, remaining meta-schedulers are difficult to deploy. Generally speaking, most of the grid brokers are designed for an all-purpose use and may not fit the needs of specific domain or business constraints. The latter situation happened in the scope of the BEinGRID (business experiments in grid) research project. This paper describes how a lightweight, configurable and easy to deploy meta-scheduler was implemented to meet those constraints and to be able to easily change business and domain specific rules while performing job scheduling and resource allocation. The resulting generic grid broker has been applied to image rendering for architects.
