Linux Clusters: The HPC Revolution 2005 is sponsored in part by the following institutions:

AMD logo

AMD (NYSE:AMD) designs and produces innovative microprocessors, Flash memory devices and low-power processor solutions for the computer, communications and consumer electronics industries. AMD is dedicated to delivering standards-based, customer-focused solutions for technology users, ranging from enterprises and governments to individual consumers.

The world's first 32-bit and 64-bit processor compatible with the x86 architecture, the AMD Opteron processor is based on AMD64 technology with Direct Connect Architecture. Direct Connect Architecture helps eliminate the bottlenecks inherent in a front-side bus by directly connecting the processors, the memory controller and the I/O to the central processor unit to enable improved overall system performance and efficiency. AMD was the first to announce the completion of an x86-based dual-core processor design and the first to demonstrate an x86-based dual-core processor for 32- and 64-bit computing. As more solution providers join the AMD64 ecosystem, the industry is approaching the day when 32-bit-only systems will become obsolete.

APC logo

APC's InfraStruXure™ is on-demand architecture for network-critical physical infrastructure (NCPI). The InfraStruXure design, which integrates power, cooling, rack, management and services, allows the selection of standardized, modular components to create a customized solution. This standardization coupled with APC's Web-based Build Out Tool enables an easily scalable architecture designed to meet changing needs and future expansion.  InfraStruXure increases system availability while decreasing design and install time from months to days, while eliminating the need for raised floors in many applications.

HPCwire continues to be devoted primarily to ongoing developments across the entire spectrum of computationally-intensive hardware, software and integrated systems technology.

HPCwire's "BREAKING NEWS" provides readers with daily HPC news and is published every Friday providing its readers with the most current news and information. HPCwire: keeping its readers in the know.

IBM logo

IBM strives to lead in the creation, development and manufacture of the industry's most advanced information technologies, including computer systems, software, networking systems, storage devices and microelectronics. IBM translates these advanced technologies into value for its customers through professional solutions and services businesses worldwide.

Intel logo

Intel, the world's largest chip maker, is also a leading manufacturer of computer, networking and communications products. Additional information about Intel is available at

Linux HPC is a Web site for system administrators, developers, and enterprise managers, offering recent industry news, events, mailing lists and links, all related to high-performance technical computing and clustering with Linux. is a community-based portal providing information on one subject: Linux high-performance computing. It is part of a small network of technical Web sites that are managed and maintained by Ken Farmer.

Linux Journal logo

Established in 1994, Linux Journal is the original monthly publication of the global Linux community, covering topics critical to intelligent implementation of the Linux operating system. Linux Journal is published by SSC Publishing, the leading Linux and open source authority, which has published reference materials in these fields since 1983. Its properties include,,,, and the monthly international print magazines TUX and Linux Journal. Additional information can be found at

Myricom logo

Myricom, Inc., a privately held California corporation founded in 1994, created Myrinet, the leading high-speed, low-latency network for connecting computers to form clusters. There are many thousands of Myrinet clusters in use worldwide. These clusters are used for computationally demanding scientific and engineering applications, and for data-intensive web and database applications. Myrinet technology is used in 38.6% of the November 2004 TOP500 sites, including clusters of up to more than 3,500 processors. In addition to direct sales, Myricom supplies Myrinet products and software to IBM, HP, Dell, Sun, Linux Networx, and many other OEM and system-integration companies.

NCSA logo

The National Center for Supercomputing Applications (NCSA) at the University of Illinois at Urbana-Champaign is a leader in developing and deploying cutting-edge high-performance computing, networking, and information technologies. NCSA is a partner in the TeraGrid project, a National Science Foundation initiative to build and deploy the world's largest, fastest, most comprehensive, distributed infrastructure for open scientific research. In addition to the NSF, NCSA receives support from the state of Illinois, the University of Illinois, private sector partners, and other federal agencies.

PathScale logo

Based in Mountain View, California, PathScale develops innovative software and hardware technologies that substantially increase the performance and efficiency of Linux clusters. PathScale offers three products focused on HPC clusters: PathScale EKOPath Compiler Suite, the world's highest performance 64-bit Linux compilers for the x86 architecture; PathScale InfiniPath, an InfiniBand-compatible interconnect that offers the lowest MPI latency for Linux x86 clusters, and PathScale OptiPath MPI Acceleration Tools, the first easy-to-use MPI performance analysis tools for scientists.

PathScale believes that 64-bit Linux clusters are the new paradigm for high-performance computing. Relative to large-scale symmetric multiprocessors, Linux clusters are easier to scale, inherently more reliable, and significantly less expensive. PathScale technologies add new capabilities to Linux clusters, ultimately enabling end users to speed up application development, deployment, and performance.
