Workflow Management System (Pegasus-WMS)

A project of the USC Information Sciences Institute and the Computer Science department at the University of Wisconsin Madison

Funded by the National Science Foundation under the OCI SDCI program, grant #0722019

Project Goal: To Deliver robust and scalable workflow management tools to the scientific community.

Introduction

As part of SDCI, we are making Pegasus-WMS  a system that is easy for a broad range of users to configure, deploy, and use on the evolving cyberinfrastructure.  We provide maintenance of the software, troubleshooting and bug fixes. We are improving the usability of our middleware by enhancing current software installation and configuration procedures and expanding the current documentation. We plan to develop user-friendly workflow execution monitoring tools as well as developing new debugging capabilities that will enable users to trace problems more efficiently.  We also plan to expand the expressiveness of the user-level workflow descriptions to support a broader range of applications.

We are committed to work with the science community to help them solve computational problems using our workflow technologies.

The first release of Pegasus-WMS, which includes the Pegasus mapper and the DAGMan workflow execution engine is expected January 2008. In the meantime you can install and use the Pegasus mapper and DAGMan from separate code distributions.
