  • This summary report describes data management and visualization activities in the Advanced Simulation and Computing (ASC) program at Lawrence Livermore National Laboratory (LLNL). The report covers the period from approximately October 2003 to June 2004 and describes activities within the Visual Interactive Environment for Weapons Simulation (VIEWS) ASC program element. This report and the references herein are intended to document the completion of the following Level 2 Milestone from the ASC FY04-05 Implementation Plan, due at the end of Quarter 3 in FY04:
  • Define a 2-5 year plan that documents facilities, operations, networking, storage and user support efforts to concentrate and coordinate resources within the ASC FOUS Program.
  • The infrastructure for transportation in the United States allows for a high level of mobility and freight activity for the current population of 300 million residents, and several million business establishments. According to a Department of Transportation study, more than 230 million motor vehicles, ships, airplanes, and railroads cars were used on 6.4 million kilometers (4 million miles) of highways, railroads, airports, and waterways in 1998. Pipelines and storage tanks were considered to be part of this deteriorating infrastructure. The annual direct cost of corrosion in the infrastructure category was estimated to be approximately $22.6 billion in 1998. There weremore » 583,000 bridges in the United States in 1998. Of this total, 200,000 bridges were steel, 235,000 were conventional reinforced concrete, 108,000 bridges were constructed using pre-stressed concrete, and the balance was made using other materials of construction. Approximately 15 percent of the bridges accounted for at this point in time were structurally deficient, primarily due to corrosion of steel and steel reinforcement. Iron-based amorphous metals, including SAM2X5 (Fe{sub 49.7}Cr{sub 17.7}Mn{sub 1.9}Mo{sub 7.4}W{sub 1.6}B{sub 15.2}C{sub 3.8}Si{sub 2.4}) and SAM1651 (Fe{sub 48}Mo{sub 14}Cr{sub 15}Y{sub 2}C{sub 15}B{sub 6}) have been developed, and have very good corrosion resistance. These materials have been prepared as a melt-spun ribbons, as well as gas atomized powders and thermal-spray coatings. During electrochemical testing in several environments, including seawater at 90 C, the passive film stabilities of these materials were found to be comparable to that of more expensive high-performance alloys, based on electrochemical measurements of the passive film breakdown potential and general corrosion rates. These materials also performed very well in standard salt fog tests. Chromium (Cr), molybdenum (Mo) and tungsten (W) provided corrosion resistance, and boron (B) enabled glass formation. The high boron content of this particular amorphous metal made it an effective neutron absorber, and suitable for criticality control applications. These amorphous alloys appear to maintain their corrosion resistance up to the glass transition temperature. Visionary research is proposed to extend the application of corrosion-resistant iron-based amorphous metal coatings, and variants of these coatings, to protection of the Nation's transportation infrastructure. Specific objectives of the proposed work are: (1) fabrication of appropriate test samples for evaluation of concept; (2) collection of production and test data for coated steel reinforcement bars, enabling systematic comparison of various coating options, based upon performance and economic considerations; and (3) construction and testing of concrete structures with coated steel reinforcement bars, thereby demonstrating the value of amorphous-metal coatings. The benefits of ceramic coatings as thermal barriers will also be addressed.« less

  • This report describes the deployment and demonstration of the first phase of the I/O infrastructure for Purple. The report and the references herein are intended to certify the completion of the following Level 2 Milestone from the ASC FY04-05 Implementation Plan, due at the end of Quarter 4 in FY05. The milestone is defined as follows: ''External networking infrastructure installation and performance analysis will be completed for the initial delivery of Purple. The external networking infrastructure includes incorporation of a new 10 Gigabit Ethernet fabric linking the platform to the LLNL High Performance Storage System (HPSS) and other center equipment.more » The LLNL archive will be upgraded to HPSS Release 5.1 to support the requirements of the machine and performance analysis will be completed using the newly deployed I/O infrastructure. Demonstrated throughput to the archive for this infrastructure will be a minimum of 1.5GB/s with a target of 3GB/s. Since Purple delivery is not scheduled until late Q3, demonstration of these performance goals will use parts of Purple and/or an aggregate of other existing resources.''« less
