The Fat-Pyramid And Universal Parallel Computation Independent Of Wire Delay, Ronald I. Greenberg

Computer Science: Faculty Publications and Other Works

This paper shows that a fat-pyramid of area Θ(A) requires only O(log A) slowdown to simulate any competing network of area A under very general conditions. The result holds regardless of the processor size (amount of attached memory) and number of processors in the competing networks as long as the limitation on total area is met. Furthermore, the result is valid regardless of the relationship between wire length and wire delay. We especially focus on elimination of the common simplifying assumption that unit time suffices to traverse a wire regardless of its length, since the assumption becomes more and more …

Toward Scalable Parallel Software: An Active Object Model And Library To Support Von Neumann Languages, George K. Thiruvathukal

Computer Science: Faculty Publications and Other Works

Scalable parallel processing has been proposed as the technology scientists and engineers can use today to solve the problems of tomorrow. Many computational Grand Challenge problems require between two and three orders of magnitude than can be provided with the scalable parallel hardware of the early nineteen-nineties. While hardware continues to become more scalable and cheaper, software is not advancing at the same pace and remains a very expensive part of systems development.

A great deal of emphasis on software technology to support scalable parallel processing is placed on von Neumann languages. One of two approaches is common: (a) augment …

Inter-Relations Of Solvable Potentials, Asim Gangopadhyaya, Prasanta K. Panigrahi, Uday P. Sukhatne

Physics: Faculty Publications and Other Works

Solvable Natanzon potentials in nonrelativistic quantum mechanics are known to group into two disjoint classes depending on whether the Schrödinger equation can be reduced to a hypergeometric or a confluent hypergeometric equation. All the potentials within each class are connected via point canonical transformations. We establish a connection between the two classes with appropriate limiting procedures and redefinition of parameters, thereby inter-relating all known solvable potentials.

A Generic Software Modeling Framework For Building Heterogeneous Distributed And Parallel Software Systems, William T. O'Connell, George K. Thiruvathukal, Thomas W. Christopher

Computer Science: Faculty Publications and Other Works

Heterogeneous distributed and parallel computing environments are highly dependent on hardware and communication protocols. The result is significant difficulty in software reuse, portability across platforms, interoperability, and an increased overall development effort. A new systems engineering approach is needed for parallel processing systems in heterogeneous environments. The generic modeling framework de-emphasizes platform- specific development while exploiting software reuse (and platform-specific capabilities) with a simple, well defined, and easily integrated set of abstractions providing a high level of heterogeneous interoperability.

Distributed Memo: A Heterogeneously Distributed And Parallel Software Development Environment, William T. O'Connell, George K. Thiruvathukal, Thomas W. Christopher

Computer Science: Faculty Publications and Other Works

Heterogeneously distributed and parallel computing environments are highly dependent on hardware, data migration, and protocols. The result is significant difficulty in software reuse, portability across platforms, and an increased overall development effort. The appearance of a shared directory of unordered queues can be provided by integrating heterogeneous computers transparently. This integration provides a conducive environment for parallel and distributed application development, by abstracting the issues of hardware and communication. Object oriented technology is exploited to provide this seamless environment.

Environmental Attitudes And Knowledge: An International Comparison Among Business Students, Raymond Benton Jr., G. Ray Funkhouser

School of Business: Faculty Publications and Other Works

This article investigates international differences in environmental knowledge and attitudes among business administration students. The Environmental Knowledge and Attitude Scale, developed by Maloney, Ward, and Braucht (1975) and used by Synodinos (1990), was administered to 85 upperdivision business administration students at Loyola University Chicago and 111 upperdivision business students at the National University of Singapore. No significant differences were found between the two samples on the Knowledge, Concern, or Willingness to Act subscales. The United States students' higher mean score on the Actual Behavior subscale was significant but may only reflect relative possibilities for participation in environmental activities. Overall, the …
