SGI Expands Portfolio of Available CAE Software for U.S. Department of Defense Applications

Silicon Graphics (OTC: SGID) today announced the addition of two important government off-the-shelf (GOTS) application software, CTH and Xpatch(R), to the growing portfolio of computer-aided engineering (CAE) software immediately available on the SGI(R) Altix(R) and Silicon Graphics Prism(TM) family of servers, clusters and visualization systems -- the first Linux(R) High-Performance Compute (HPC) environment capable of scaling to hundreds of Intel(R) Itanium(R) 2 processors with distributed shared-memory and integrated visualization. CTH, a widely-used shock wave physics software that simulates high speed impact and penetration, and Xpatch, an electromagnetics radar simulation software suite for predicting and analyzing high frequency signatures, are now fully optimized for SGI systems.
Significant numbers of U.S. Department of Defense (DoD) research organizations, agencies and prime contractors rely on CAE applications to improve design quality, mission and target precision and to reduce design-cycle time and costs in the development of warfighter systems for sea, land, air, and space-based defense applications. By combining the leading HPC technologies of the Intel Itanium 2 processors, the open-source 64-bit Linux operating system and SGI(R) NUMAflex(TM) scalable system architecture, the SGI Altix and Silicon Graphics Prism family of systems can offer the capability to meet the essential needs of CAE simulation environments for advanced DoD weapons development.
CTH and Shock Wave Physics
Developed by Sandia National Laboratories, CTH is a widely-used shock wave physics software that simulates high-speed impact and penetration phenomena involving a variety of materials. Uses of CTH software include studying weapon effects, armor/anti-armor interactions, warhead design, high-explosive initiation physics and weapon safety considerations. Primary users include DOE national laboratories, the U.S. Army, Navy, Air Force and other DoD-sponsored research and development organizations. CTH is also used in national missile defense, hazardous material dispersal by explosive detonation, weapon components design and reactive materials research.
This release of CTH v7.0 includes performance enhancements from code optimizations invoked with the Intel compiler, and the use of SGI(R) Message Passing Toolkit (MPT) which provides industry-standard message-passing libraries optimized for SGI systems running Linux. These high-performance libraries permit application developers to use standard, portable interfaces for developing parallel applications software while obtaining the best possible communications performance.
Xpatch and High Frequency Electromagnetics
Xpatch, developed by Science Applications International Corporation (SAIC) is a premier electromagnetic software suite for predicting and analyzing high-frequency radar signatures. Xpatch is a set of prediction and analysis tools that use the shooting-and-bouncing ray (SBR) method to predict realistic far-field and near-field radar signatures for 3D target models. SAIC also develops and distributes SAF, a method of moments full-wave solver for low frequency electromagnetics predictions, which is also available for SGI Altix.
The Xpatch toolset is used by the U.S. Air Force Research Laboratory and Defense Advanced Research Projects Agency (DARPA) for multiple radar simulation programs. There are over 500 organizations across the U.S. in both industrial and government applications using Xpatch to produce and analyze scattering data for realistic aircraft, missiles, ships, spacecraft and ground vehicles.
According to Luke Lin, deputy division manager, SAIC, "The technology and applications engineering investments from SGI and Intel provide SAIC with a solid foundation for Xpatch software development and radar cross-section simulation, design and analysis. The computing capabilities of the SGI Altix and the Silicon Graphics Prism's ability to tightly integrate HPC with advanced visualization can provide efficient and cost-effective simulation environments for SAIC's computational electromagnetics applications."
SGI Focus on the CAE Simulation Workflow
The current DoD challenges in CAE workflow requirements continue to benefit from the industry-leading SGI technology of HPC servers and clusters for computation, visualization systems for pre- and post-processing, and file management solutions for CAE simulation data.
The availability of CTH and Xpatch build upon SGI's and Intel's already successful efforts to offer DoD-critical CAE software from the GOTS community, and commercial off-the-shelf (COTS) CAE software from a variety of independent software vendors. Samples of available GOTS and COTS software for CAE simulation include:

"SGI is helping to advance a growing class of DoD scientists, researchers and engineers who are moving from proprietary architectures to industry standard technologies that drive value and efficiencies into their CAE workflow," said Anthony Robbins, president, SGI Federal. "We are satisfied in our joint-collaboration with Intel as we focus on our growing list of application software developers that further enhance DoD's capabilities in CAE simulation for the warfighter."
