Evaluation of architectural paradigms for addressing theprocessor-memory gap (open access)

Evaluation of architectural paradigms for addressing theprocessor-memory gap

Many high performance applications run well below the peak arithmetic performance of the underlying machine, with inefficiencies often attributed to poor memory system behavior. In the context of scientific computing we examine three emerging processors designed to address the well-known gap between processor and memory performance through the exploitation of data parallelism. The VIRAM architecture uses novel PIM technology to combine embedded DRAM with a vector co-processor for exploiting its large bandwidth potential. The DIVA architecture incorporates a collection of PIM chips as smart-memory coprocessors to a conventional microprocessor, and relies on superword-level parallelism to make effective use of the available memory bandwidth. The Imagine architecture provides a stream-aware memory hierarchy to support the tremendous processing potential of SIMD controlled VLIW clusters. First we develop a scalable synthetic probe that allows us to parametize key performance attributes of VIRAM, DIVA and Imagine while capturing the performance crossover points of these architectures. Next we present results for scientific kernels with different sets of computational characteristics and memory access patterns. Our experiments allow us to evaluate the strategies employed to exploit data parallelism, isolate the set of application characteristics best suited to each architecture and show a promising direction towards interfacing leading-edge …

Colorado Energy and Cost Savings for New Single- and Multifamily Homes: 2009 and 2012 IECC as Compared to the 2006 IECC (open access)

Colorado Energy and Cost Savings for New Single- and Multifamily Homes: 2009 and 2012 IECC as Compared to the 2006 IECC

The 2009 and 2012 International Energy Conservation Codes (IECC) yield positive benefits for Colorado homeowners. Moving to either the 2009 or 2012 IECC from the 2006 IECC is cost-effective over a 30-year life cycle. On average, Colorado homeowners will save $1,528 over 30 years under the 2009 IECC, with savings still higher at $5,435 under the 2012 IECC. Each year, the reduction to energy bills will significantly exceed increased mortgage costs. After accounting for up-front costs and additional costs financed in the mortgage, homeowners should see net positive cash flows (i.e., cumulative savings exceeding cumulative cash outlays) in 2 years for the 2009 and 2 years with the 2012 IECC. Average annual energy savings are $119 for the 2009 IECC and $392 for the 2012 IECC.

Opportunities to change development pathways toward lower greenhouse gas emissions through energy efficiency (open access)

Opportunities to change development pathways toward lower greenhouse gas emissions through energy efficiency

There is a multiplicity of development pathways in which low energy sector emissions are not necessarily associated with low economic growth. However, changes in development pathways can rarely be imposed from the top. On this basis, examples of energy efficiency opportunities to change development pathways toward lower emissions are presented in this paper. We review opportunities at the sectoral and macro level. The potential for action on nonclimate policies that influence energy use and emissions are presented. Examples are drawn from policies already adopted and implemented in the energy sector. The paper discusses relationships between energy efficiency policies and their synergies and tradeoffs with sustainable development and greenhouse gas emissions. It points to ways that energy efficiency could be mainstreamed into devel?opment choices.

Study of the properties of mine waste in the midwestern coal fields. Phase I report (open access)

Study of the properties of mine waste in the midwestern coal fields. Phase I report

In an effort to assist the coal industry in complying with the applicable regulations, to design safe and environmentally acceptable disposal systems, and to encourage secondary use of coal mine waste, the US Department of Energy has initiated research programs to develop coal mine waste disposal and use technology. This study of the properties of mine wastes in the Midwestern coal fields has been limited to the waste materials obtained from underground coal mines and preparation plants attached to both underground and surface mines. The program has been divided into two phases. In Phase I, the 20 most important properties relevant to safe disposal, reclamation, underground disposal, and secondary uses have been identified. An inventory of the significant waste disposal sites in the Midwestern coal fields has been prepared. The site locations have been plotted on USGS maps. Estimates of coal production and coal mine waste production during the next 2 decades have been prepared and are presented in this report. Also, all available information obtained from a search of existing literature on physical and chemical properties, including analysis results of the general runoff from the refuse disposal areas, has been collected and is presented. In order to fill the …

Test and demonstration of a 1-MW wellhead generator: helical screw expander power plant, Model 76-1. Final report to the International Energy Agency (open access)

Test and demonstration of a 1-MW wellhead generator: helical screw expander power plant, Model 76-1. Final report to the International Energy Agency

A 1-MW geothermal wellhead power plant incorporating a Lysholm or helical screw expander (HSE) was field tested between 1980 and 1983 by Mexico, Italy, and New Zealand with technical assistance from the United States. The objectives were to provide data on the reliability and performance of the HSE and to assess the costs and benefits of its use. The range of conditions under which the HSE was tested included loads up to 933 kW, mass flowrates of 14,600 to 395, 000 lbs/hr, inlet pressures of 64 to 220 psia, inlet qualities of 0 to 100%, exhaust pressures of 3.1 to 40 psia, total dissolved solids up to 310,000 ppM, and noncondensible gases up to 38% of the vapor mass flow. Typical machine efficiencies of 40 to 50% were calculated. For most operations efficiency increased approximately logarithmically with shaft power, while inlet quality and rotor speed had only small effects. The HSE was designed with oversized internal clearances in the expectation that adherent scale would form during operation. Improvements in machine efficiency of 3.5 to 4 percentage points were observed over some test periods with some scale deposition. A comparison with a 1-MW back-pressure turbine showed that the HSE can compete …

Program GROUPIE (version 79-1): calculation of Bondarenko self-shielded neutron cross sections and multiband parameters from data in the ENDF/B format

Program GROUPIE reads evaluated data in the ENDF/B format and uses these data to calculate Bondarenko self-shielded cross sections and multiband parameters. To give as much generality as possible, the program allows the user to specify arbitrary energy groups and an arbitrary energy groups and an arbitrary energy-dependent neutron spectrum (weighing function). To guarantee the accuracy of the results, all integrals are performed analytically; in no case is iteration or any approximate form of integration used. The output from this program includes both listings and multiband parameters suitable for use either in a normal multigroup transport calculation or in a multiband transport calculation. A listing of the source deck is available on request.

The computer code LINEAR converts evaluated cross sections in the ENDF/B format into a form that can be defined by applying linear--linear interpolation to energy and cross section parameters. The code also thins those sections already in that form. The main advantage of the code is that it eliminates the need for any subsequent code to consider anything but linear--linear data. 2 figures.

The unusual stability of TATB (1,3,5-triamino-2,4,6-trinitrobenzene): A review of the scientific literature (open access)

The unusual stability of TATB (1,3,5-triamino-2,4,6-trinitrobenzene): A review of the scientific literature

This review is intended as an up-to-date review of the scientific literature on TATB since its discovery as a high explosive. In particular, it focuses on clarifying our current understanding of the relationship between the structure of TATB and its unique thermal stability. We review a large number of different publications by many authors. A small portion of the work on TATB'' presented actually consists of experimental studies on TATB formulated as PBX-9502 or as LX-17. Where relevant, this distinction is indicated. However, inasmuch as this review focuses on thermal response and the relationship of chemical reactivity to the molecular and lattice structure of TATB as a pure material, results from these other formulations may not be directly applicable, and in general we have omitted them. 4 refs.
