Virtual Machines and Types of Service for TeraGrid Computing Foundational capabilities we provide in TeraGrid, such as "roaming" access and a "coordinated" software environment, open new possibilities in terms of more specialized services, or to allow the TeraGrid, as a system, to respond to supply and demand. For example, a resource provider might elect to increase the "price" of a queue in order to improve turnaround time by reducing demand, or decrease the price to increase demand (and thus utilization).
Last week I moderated a webinar entitled Optimizing Performance for HPC: Part 2 - Interconnect with InfiniBand. It was a great presentation with a lot of practical information and good questions. If you missed it, it will be available for a few months, so you still have a chance to check it out. As part of the webinar, Vallard Benincosa of IBM, mentioned that the speed of light was a becoming an issue in network design. In engineering terms, that is refered to as a hard limit.
IBM's future Power7 chip may be just about done as far as the engineering is concerned, and its server designs might also be more or less completed as well. But there is plenty of time yet to tweak the boxes, and I doubt very much that the final packaging and pricing for the future Power7 machinery is anywhere close to being set. Which is a pity, really.
Jay Boisseau, widely credited with bringing the University of Texas from Nowheresville to near the front of the pack in the world of supercomputing, "is a force of nature," says UT Earth scientist Omar Ghattas.
Building and Promoting a Linux-based Operating System to Support Virtual Organizations for Next Generation Grids (2006-2010). The emergence of Grids enables the sharing of a wide range of resources to solve large-scale computational and data intensive problems in science, engineering and commerce. While much has been done to build Grid middleware on top of existing operating systems, little has been done to extend the underlying operating systems to enablee and facilitate Grid computing, for example by embedding important functionalities directly into the operating system kernel.
Multi-million dollar supercomputers take up most of the headlines, but many organizations are now considering the addition of smaller, personal supercomputers to their desktop fleet. Despite some strong global sales, find out why the idea still hasn’t taken off at most companies
You read that right. Now you can show up at your next tour or high school science fair judging with a confident swagger, knowing you have a secret weapon: the best darn presentation ever about what HPC is all about, and why everyone should care.
