The purpose of this list is to provide a ranking of the most energy-efficient supercomputers in the world and serve as a complementary view to the TOP500 List.
This one-day symposium will explore the use of GPUs and Cell processors for scientific and high performance computing. SHARCNET has deployed high-performance clusters containing both architectures, and this symposium will give researchers the chance to learn about these new technologies from keynote speakers who are at the forefront of research in this field.
The aim of the DIET project is to develop a set of tools to build computational servers. Huge problems can now be computed over the Internet thanks to Grid Computing Environments like Globus or Legion. Because most of current applications are numerical, the use of libraries like BLAS, LAPACK, ScaLAPACK or PETSc is mandatory. The integration of such libraries in high level applications using languages like Fortran or C is far from being easy. Moreover, the computational power and memory needs of such applications may of course not be available on every workstation. Thus, the RPC seems to be a good candidate to build Problem Solving Environments on the Grid. Several tools following this approach exist, like Netsolve, NINF, NEOS, or RCS.
Personal supercomputers that lash together a stack of graphics processing units and can sit on a desktop are becoming popular with researchers. These machines can be used to run calculations by the desk instead of waiting for time on one of the national supercomputers.
Before specialized graphics-processing chips existed, pioneers in the field of visualization used multicore supercomputers to realize data in three dimensions. Today, however, the speed at which supercomputers can process data is rapidly outstripping the speed at which they can input and output that data. Graphics-processing clusters are becoming obsolete.
EUCALYPTUS - Elastic Utility Computing Architecture for Linking Your Programs To Useful Systems - is an open-source software infrastructure for implementing "cloud computing" on clusters. The current interface to EUCALYPTUS is compatible with Amazon's EC2 interface, but the infrastructure is designed to support multiple client-side interfaces. EUCALYPTUS is implemented using commonly available Linux tools and basic Web-service technologies making it easy to install and maintain.
As computational scientists are confronted with increasingly massive datasets from supercomputing simulations and experiments, one of the biggest challenges is having the right tools to gain scientific insight from the data. One common method for gaining insight is to use scientific visualization, which transforms abstract data into more readily comprehensible images using advanced computer software and computer graphics. But the ever-growing size of scientific datasets presents a significant challenge to modern scientific visualization tools. As a result, there is a great deal of motivation to explore use of large, parallel resources, such as those at the U.S. Department of Energy's (DOE) supercomputing centers, to take advantage of their vast computational processing power, I/O bandwidth and large memory footprint.
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.
"This project," said Sergiu Sanielevici, PSC director of scientific applications and user support, who also leads user support and services for the TeraGrid, "exemplifies how powerful systems like Pople can open doors to data-mining and data-centric research in fields not traditionally associated with HPC, such as the social sciences, and make it possible to get answers that would otherwise be impractical or impossible." PSC supported this project through the NSF TeraGrid program, which allocates large-scale computing resources free to researchers at U.S. universities on a peer-review proposal basis.
"For a while now, IBM has had multiple and competing tools for managing AIX and Linux clusters for its supercomputer customers and yet another set of tools that were used for other HPC setups with a slightly more commercial bent to them. But Big Blue has now cleaned house, killing off its closed-source Cluster Systems Management (CSM) tool and tapping its own open source Extreme Cluster Administration Toolkit (known as xCAT) as its replacement."
NVIDIA Corporation, the world leader in visual computing technologies and the inventor of the GPU, today announced that the Korea Institute of Science and Technology Information (KISTI) Supercomputing Center has selected NVIDIA Quadro® FX 5600 graphics c
