Microsoft Funds Research in Cycle Harvesting at UC Berkeley


Deb Agarwal, who heads CRD's Distributed Systems Department, along with Yoram Rubin, a professor in Civil Engineering on campus, were recently awarded a $35,000 grant from Microsoft's Technology Computing Initiative to develop a cycle harvesting portal. Their research proposal, “Combining Disparate Donated HPC Computational Resources into an Integrated Environment,” explains how synthesis in hydrology can be aided through development of a user portal.

A vital component of synthesis will be making computing capabilities available to allow modeling and analysis at regional and global scales. Several HPC resources are available, but these donations are useless without a means for researchers to easily utilize them. We will develop a portal to provide a single point of authentication and authorization for users along with access to a model repository and data. This new portal would provide mechanisms for researchers to authenticate and launch computations by choosing a model, a dataset, and a computational resource. In the longer term, the portal will offer resource advice based on location of data, type of computation, expected running time of computation, model compatibility with computational resource, and other factors as necessary.


CITRIS Distinguished Speaker Talk TODAY: Sun Microsystems' Dr. Marc Tremblay


Dr. Marc Tremblay, Sun Fellow, VP and Chief Architect, Scalable Systems Group of Sun Microsystems, Inc., will be presenting "High-Performance Throughput Computing” this afternoon at 4 p.m. in 306 Soda Hall on the UC Berkeley Campus. His talk is one in a series of CITRIS Distinguished Speakers. There is a reception to follow in Soda Hall.

Here's the abstract:

Throughput computing, achieved through a new generation of microprocessors composed of multiple multi-threaded cores, can lead to performance improvements that are 10 to 30 times those of conventional processors and systems. This talk will discuss how the value of a robust, high-performance single thread leads to even higher throughput rates. I will also describe some of the techniques we are implementing in future mainstream processors that accomplish the somewhat conflicting goal of attacking both latency and throughput.

About Computing Sciences at Berkeley Lab

The Lawrence Berkeley National Laboratory (Berkeley Lab) Computing Sciences organization provides the computing and networking resources and expertise critical to advancing the Department of Energy's research missions: developing new energy sources, improving energy efficiency, developing new materials and increasing our understanding of ourselves, our world and our universe.

ESnet, the Energy Sciences Network, provides the high-bandwidth, reliable connections that link scientists at 40 DOE research sites to each other and to experimental facilities and supercomputing centers around the country. The National Energy Research Scientific Computing Center (NERSC) powers the discoveries of 6,000 scientists at national laboratories and universities, including those at Berkeley Lab's Computational Research Division (CRD). CRD conducts research and development in mathematical modeling and simulation, algorithm design, data storage, management and analysis, computer system architecture and high-performance software implementation. NERSC and ESnet are DOE Office of Science User Facilities.

Lawrence Berkeley National Laboratory addresses the world's most urgent scientific challenges by advancing sustainable energy, protecting human health, creating new materials, and revealing the origin and fate of the universe. Founded in 1931, Berkeley Lab's scientific expertise has been recognized with 13 Nobel prizes. The University of California manages Berkeley Lab for the DOE’s Office of Science.

DOE’s Office of Science is the single largest supporter of basic research in the physical sciences in the United States, and is working to address some of the most pressing challenges of our time. For more information, please visit science.energy.gov.
