Pegasus 4.0 Released!

Pegasus

Delivers robust and scalable workflow management tools to the scientific community!

The Pegasus project encompasses a set of technologies that help workflow-based applications execute in a number of different environments including desktops, campus clusters, grids, and now clouds. Scientific workflows allow users to easily express multi-step computations, for example retrieve data from a database, reformat the data, and run an analysis. Once an application is formalized as a workflow the Pegasus Workflow Management Service can map it onto available compute resources and execute the steps in appropriate order. Pegasus can easily handle workflows with several million computational tasks.

Pegasus in the cloud

 
Cloud computing is a new way of thinking about large-scale computing infrastructure. It combines utility computing with virtualization to provide highly configurable computational resources for business and science applications.

There are many different cloud computing architectures in use. These include:
