Conveyor: a workflow engine for bioinformatic analyses

Workflow Engine for Clouds

A workflow models a process as consisting of a series of steps that simplifies the complexity of execution and management of applications. Scientific workflows in domains such as high-energy physics and life sciences utilize distributed resources in order to access, manage, and process a large amount of data from a higher level. Processing and managing such large amounts of data require the use...

CiAN: A Workflow Engine for MANETs

The practice of using workflows to model complex activities in stable networks is commonplace and is supported by many commercially available workflow management systems (WfMSs). However, the use of workflows to model collaborative activities in mobile environments, while possible at the model level, has not gained traction due to the lack of a suitable WfMS for mobile networks and devices. Thi...

Developing a reusable workflow engine

Every time a workflow solution is conceived there is a large amount of functionality that is eventually reinvented and redeveloped from scratch. Workflow management systems from academia to the commercial arena exhibit a myriad of approaches having as much in common as in contrast with each other. Efforts in standardizing a workflow reference model and the gradual endorsement of those standards...

Media360 Workflow-Implementing a Workflow Engine Inside a Database

I describe a Workflow Management System, where the workflow engine is implemented inside a database. The focus here is on the architectural approach and on the lessons learned from a commercial implementation in the workflow component of the Informix Media 360 content management solution. Conceptually, the two main primitives of workflow are activities, which represent the work items of a large...
