Urgent computing

Charlie Catlett has an interesting post on the TeraGrid Whiteboard about a new system developed at Argonne to support urgent computing:

Pete [Beckman, at Argonne National Lab] and his team have developed an interesting capability called Special Priority and Urgent Computing Environments (SPRUCE) to give resource providers a set of tools to implement local policy for dealing with high-urgency jobs.

This kind of capability has a variety of uses for enabling infrastructure to respond to urgent computing needs, ranging from harnessing large-scale systems to enabling service providers to automatically contribute smaller resources to ensemble computing arrangements
