Computing

Design of the Red Storm supercomputing system was completed in a joint effort with Cray Inc. With a peak speed of more than 40 trillion operations per second, Red Storm will be the world's fastest computer when delivered in the fall of 2004. This 10-fold increase in computing capability over Sandia's current system will enable dramatically enhanced simulations of weapons performance and safety, leading to important new insights in stockpile stewardship. (9200, 9300, 9900, 9100, 8900)

3-D resistive magnetohydrodynamics (MHD) modeling implemented in Sandia's ALEGRA code has been used to simulate Z-pinch wire array implosions at levels of detail never before attempted. Nonuniform plasma streamers like those observed experimentally have been computed and can be understood in terms of interactions between local and global magnetic field topologies. Such new physical insights into these phenomena, gained by collaboration of computational physicists and experimentalists, are critical to scaling up to higher currents and radiation pulses on Sandia's Z machine. (9200, 1600)

The new Supercomputer Annex (SCA) was built in preparation for the Red Storm computing system. This ~20,000-square-foot facility will provide up to seven megawatts of electrical power and 4,000 tons of cooling. Additionally, a network infrastructure for Red Storm was developed and will provide a total of 1.2 terabits of switched capacity. (9300, 10800)

An essential ADAPT milestone was reached with a demonstration of the secure collaborative engineering and manufacturing environment being developed for the Nuclear Weapons Complex. The demonstration consisted of an eight-site classified videoconference with 70 participants; the system has the capacity to handle up to 24 sites. This milestone was the first step in an overall plan that will lead to model-based qualification of War Reserve assembly at Pantex. (8200, 8900, 9900)

The Common Component Architecture was founded in 1998 as a grass roots organization of DOE laboratories and universities dedicated to developing a software component system for high-performance computing. Software components are an approach to constructing computer simulations analogous to the way that a radio is constructed out of electrical components. In this way, mixing and matching components can create many different high-performance applications. Using pre-built components for a simulation can meet national needs more quickly and bring together the knowledge of potentially hundreds of researchers. (8900)

Sandia's circuit modeling code, Xyce, running on the ASCI White supercomputer, was used to simulate the largest circuit (14 million devices) ever attempted to be modeled. Xyce is a new massively parallel object-oriented circuit simulation code. Xyce has also been used for predictive modeling of radiation effects in electronics and has been applied to the Permafrost Application Specific Integrated Circuit. New time-parallel algorithms are being developed to enable long-time simulations. (9200, 1700)

Sandia researchers have worked with the Cancer Research and Treatment Center at UNM to develop a methodology to computationally design more potent inhibitors of LFA-1/ICAM-1 binding reaction that is important to leukocyte trafficking. Our novel methodology is based on the transfer of molecular design technology that was previously applied to materials work. This work has successfully resulted in potential new compounds, and we have applied with UNM to the National Institutes of Health to continue this work. (9200)

The Trilinos framework was developed and released to facilitate the design, development, integration, and ongoing support of mathematical software libraries for modeling and simulation applications. A suite of packages including scalable solvers and efficient implementations of common routines are already available with the framework. Trilinos was released publicly on Oct. 1, 2003, and there were more than 100 downloads in the first month. (9200)

Sandia has a large, complex enterprise network of applications, servers, databases, network service, router/switches, and PCs. Maintaining the integrity of this system is critical because it is integral to Sandia's mission work. This year a prototype Cyber Enterprise Management (CEM) system was deployed, creating a framework for an integrated set of tools and processes for end-to-end improvements in security, performance, configuration, and faults. A purpose-built facility, the Integrated Network Security and Reliability Center, was completed in November 2003, enabling co-location of subject matter experts for better communication, coordination, and more rapid response to events. (9300)

Under the corporate plan for enabling wireless networking for business purposes, prototype networks have been deployed at the California and New Mexico sites. Wireless is a key element in network communication advances that will enable portable connectivity and increased functionality. A wireless security plan for corporate use of wireless has been approved by DOE/SSO, and limited deployment is scheduled to begin in 2004.

In September, Sandia's newest High Performance Computer resources were released to the entire Sandia user community. The resources, named Institutional Computing Cluster, are composed of three Linux-based high-performance clusters totaling more than seven teraflops in raw computational power and 25 terabytes total disk storage. There are two 256-node systems in New Mexico, and a 128-node cluster in California. (9300, 8900)

In May, Telecommunications Dept. 9334 was the first large department at Sandia to obtain certification under the 2000 version of the ISO-9000 standard. Using these certified processes, we completed the upgrade to the 5ESS switch; established telecommunications service to the MESA-TOP (EMCORE) facility; deployed the new "all-fiber" standard in Bldgs. 752, 753, and 969; and activated the telephone firewall (Telewall). (9300)

The Engineering Sciences Analysis Process supports the analysis processes used by several Labs organizations by providing an automated method to organize and manage planning documents, analysis artifacts, reviews, and documentation. A development plan and initial implementation pilot was delivered in FY03 and the remainder of the functionality is being added. The process provides a defined level of formality for analysis work that can be managed and tracked with the workflow tool. (9500, 9100, 8700, 15300)

Weaponeers now have nearly instant access to engineering information on our nuclear weapons stockpile via the classified network. The Nuclear Weapons information environment (NWie) portal is a secure web-based application being developed jointly by personnel from 9500, 2900, and 9900. The portal provides access to design definition drawings, engineering bill of materials, system summaries typically found in the Bomb Book, Major Assembly Releases, Military Characteristics, Stockpile-to-Target- Sequence documentation, weapon development reports, and other resources. (9500, 2900, 9900)

The computing and procedural support infrastructure has been established that will enable Labs design engineers to remotely access Interactive Electronic Procedures (IEPs) at Pantex from their classified thin-client or desktop computer. The IEP project is resident at the Pantex Plant with representation across the nuclear weapons complex. Remote access involves connection to Pantex through SecureNet, using authentication protocols. The procedural infrastructure involves provision for help desk support and official documentation for system upgrades. (9600, 9300)

The Advanced Simulation and Computing element of the Simulation Enabled Product Realization Program achieved two major programmatic Level 1 milestones to:

These milestones are critical steps in providing required applications and computing environment to certify that the W76-1 and W80-3 Stockpile Life Extension Programs will meet their Stockpile-to-Target-Sequence requirements. (1700, 9200, 9300, 8200, 8900, 9100, 9900, 15300)

A web-enabled US Savings Bond application was developed and deployed, allowing

employees to manage their bond purchases online. Features include updating bond deduction amounts, bond types, co-owners, and beneficiaries. The previous online capability generated forms that were manually input by Payroll. The new application provides real-time input into the PeopleSoft system. Eliminating duplicate data input reduced the administration time by 97.9 percent. The application increased data accuracy and timeliness and won a gold President's Quality Award. (3500, 9500, 10500)
