Workflow Management Through Cobalt

Workflow management is an important part of scientific experiments. A common pattern that scientists are using is based on repetitive job execution on a variety of different systems, and managing such job execution is necessary for large-scale scientific workflows. The workflow system should also be client-based and able to handle multiple security contexts to allow researchers to take advantage of a diverse array of systems. We have developed, based on the Java Commodity Grid Kit (CoG Kit), a sophisticated and extensible workflow system that seamlessly integrates with the queueing system Cobalt through the advanced features provided by the CoG Kit.
