Abstract

This document provides an understanding of the near and long term computing and I/O resources in the Secure Computing Facility (SCF) and Open Computing Facility (OCF). Requirements for data flows, storage capacities and transfer rates are determined. Recommendations are made for architectures, timeframes for major deliverables, and procurements for the next fiscal year.

  • This document provides an understanding of the near and long term computing and I/O resources in the Secure Computing Facility (SCF) and Open Computing Facility (OCF). Requirements for data flows, storage capacities and transfer rates are determined. Recommendations are made for architectures, timeframes for major deliverables, and procurements for the next fiscal year.
  • This document describes I/O focused requirements, issues, options, plans, deliverables and budgets for Livermore Computing (LC) in FY02. Areas covered include I/O for archival storage, network, platform, visualization and the I/O Testbed. Implementation Plan (IP) milestones and tasks in each of these areas map to the efforts and plans described in this document. When developing FY02 I/O requirements, a survey of key LC customers was performed (see Appendix A and D) and DisCom2 requirements were gathered. The LC customer provided throughput and capacity estimates were quite conservative when compared to ASCI curve projections and were history-based rather than being basedmore » on hardware capabilities. Because substantial differences exist in the ASCI platform in FY02, required I/O throughput rates were raised appropriately (i.e., by over 200% platform-to-archive). Archive capacity requirements remain fairly stable in FY02 as aggressive FY01 plans and purchases will accommodate most of the volume of data received through FY02. 10 Gigabit Ethernet network infrastructure will begin to get deployed in early FY02. When full implementation becomes cost effective it will allow us to greatly increase bandwidth between computer facilities. In addition pre-production OC-48 Ultrafastlane encryptors will be installed in early FY02 at each of the Tri-Labs. Preliminary testing of these encryption units and production unit installation will also take place in FY02. Significant network tuning, routing and protocol efforts will be investigated during FY02. These include channel bonding, gigabit ethernet flow control and HPSS protocol enhancements. Changes to and investigation of archive mover platforms and tape technologies are planned in FY02. 1BM tape robotics and tape devices will be phased out. New Storage Area Network (SAN) and platform-based mover architectures will be prototyped and investigated as approaches capable of significantly reducing archive expenditures in support of future 60 or 100 TFLOP platforms. Disaster recovery and RAIT device strategies will be formulated and HTAR porting (machine-to-machine and Linux) and deployment efforts will be completed. The I/O Testbed will continue to be instrumental in pursuit of procuring reliable high performance hardware and software solutions. The Testbed will be used to provide a proof-of-concept for both the direct-to-tape and HPSS SAN investigations, as well as for benchmarking new node and disk platforms and storage devices. Implementation of the FY02 I/O Blueprint will require $2.2M in network investments, $6.25M in archive improvements and a $.37M I/O Testbed investment. Manpower costs will remain constant. The requirements justifying these costs are found in Appendix A. The procurements are detailed in Appendix E.« less
  • Results are given of a spacecraft-electric-generating and propulsion- system integration study. This program consisted of the adaptation of the so- called LEADER technique to the analysis of nuclear-electric power and propulsion systems integration. Analytical models of each of the major components of a 350 kw spur-arc jet system and a 1 Mw spur-ion engine system were developed and processed by the LEADER optimization technique in order to demonstrate its capabilities for obtaining the design criteria for minimizing overall system weight. The specific output of the program included the optimum design variables, the constraints preventing further design improvement, and the sensitivitymore » of the final design to subsequent changes in the independent design variables.

  • The economic success of an Ocean Thermal Energy Conversion (OTEC) system is highly dependent on a platform which provides adequate support for the power system, accommodates reliably the cold water pipe, and is most cost effective. The results of a study conducted for the Department of Energy to assess six generic types of platforms to determine the most satisfactory platform for severl potential sites are presented. The six platform configurations are ship, circular barge, semi-submersible, Tuned Sphere, submersible, and spar. These represent directional and symmetric types of platforms which operate on the surface, at the interface, and submerged. The fivemore » sites for this study were primarily New Orleans, Keahole Point (Hawaii), Brazil, and secondarily Key West and Puerto Rico. Electrical transmission of energy by submarine cable is the planned form of energy transmission for all sites except Brazil, where chemical conversion is to be the method of transmission. This study is devoted to the platform (or ocean systems) of the OTEC plant which is chiefly comprised of the hull and structure, the seawater system, the position control system, and miscellaneous support/assembly systems. The principal elements in the work breakdown structure for the commercial plants are presented. The assessment of the six platform configurations was conducted utilizing a baseline plan (100-MW(e) (Net)) and site (New Orleans) with variations from the baseline to cover the range of interested platforms and sites.« less
  • The report documents the procedures used by the Texas Transportation Institute in developing Neuces County Mobile Source Emissions Inventories for FY93, FY96, FY99, and FY07. The emissions inventories are submitted in support of the Coastal Oxidant Assessment for Southeast Texas (COAST) Project. COAST is a large-scale study conducted by the Texas Natural Resource Conservation Commission to model the formation of ozone in the Houston-Galveston and Beaumont-Port Arthur air quality nonattainment areas. The software used for these procedures is described in Research Report 1279-9, `Texas Mobile Source Emissions Software Version 2.0: User`s Manual.` No further implementation of the materials in thismore » report is needed.« less
