Status and Future Perspectives for Lattice Gauge Theory Calculations to the Exascale and Beyond
In this and a set of companion whitepapers, the USQCD Collaboration lays out
a program of science and computing for lattice gauge theory. These whitepapers
describe how calculation using lattice QCD (and other gauge theories) can aid
the interpretation of ongoing and upcoming experiments in particle and nuclear
physics, as well as inspire new ones.Comment: 44 pages. 1 of USQCD whitepapers
Attitudinal and behavioural determinants influencing decision makers when adopting integration technologies in local government
Over the last few years, the advent of innovative
or revolutionary integration technologies has
influenced pivotal decisions within top management
to strategically transform Local Government
Authorities (LGAs). These technologies may
represent a huge cost for adopting LGAs, but may
also offer the chance to achieve competitive
advantage through superior service delivery. With
the emergence of electronic Government (e-
Government), LGAs are turning to integration
technologies to fully automate and e-enable their
business processes and integrate their IT
infrastructures. While prior research on the adoption
of integration technologies in the private and public
domain has considered several determinants (e.g.
benefits, barriers, costs), little attention has been
given to investigate the attitudinal and behavioural
determinants influencing top management’s decision
making process for the adoption of integration
technologies in LGAs. Notwithstanding, the
implications of this research have yet to be assessed,
leaving scope for timeliness and novel research.
Therefore, it is of high importance to investigate this
area within LGAs and contribute to the area of
strategic decision making by examining attitudinal
and behavioural determinants of top management in
relation to integration technologies adoption
Financial Architecture and Economic Performance: International Evidence
The paper examines the relations between the architecture of an economy's financial system - its degree of market orientation - and economic performance in the real sector. We argue that the relative effectiveness of bank-based versus market-based financial systems depends on the strength of the contractual environment and the extent of agency problems in the economy. We find that while market-based systems outperform bank-based systems among countries with developed financial sectors, bank-based systems fare better among countries with underdeveloped financial sectors. Countries dominated by small firms grow faster in bank-based systems and those dominated by larger firms in market-based systems. The findings suggest that recent trends in financial development policies that indiscriminately prescribe market-oriented financial-system-architecture to emerging and transition economies might be misguided because suitable financial architecture, in and of itself, could be a source of value.http://deepblue.lib.umich.edu/bitstream/2027.42/39833/3/wp449.pd
Computer architecture for efficient algorithmic executions in real-time systems: New technology for avionics systems and advanced space vehicles
Improvements and advances in the development of computer architecture now provide innovative technology for the recasting of traditional sequential solutions into high-performance, low-cost, parallel system to increase system performance. Research conducted in development of specialized computer architecture for the algorithmic execution of an avionics system, guidance and control problem in real time is described. A comprehensive treatment of both the hardware and software structures of a customized computer which performs real-time computation of guidance commands with updated estimates of target motion and time-to-go is presented. An optimal, real-time allocation algorithm was developed which maps the algorithmic tasks onto the processing elements. This allocation is based on the critical path analysis. The final stage is the design and development of the hardware structures suitable for the efficient execution of the allocated task graph. The processing element is designed for rapid execution of the allocated tasks. Fault tolerance is a key feature of the overall architecture. Parallel numerical integration techniques, tasks definitions, and allocation algorithms are discussed. The parallel implementation is analytically verified and the experimental results are presented. The design of the data-driven computer architecture, customized for the execution of the particular algorithm, is discussed
