The Anatomy of the Grid - Enabling Scalable Virtual Organizations

by Ian Foster, Carl Kesselman, Steven Tuecke - International Journal of Supercomputer Applications , 2001
"... "Grid" computing has emerged as an important new field, distinguished from conventional distributed computing by its focus on large-scale resource sharing, innovative applications, and, in some cases, high-performance orientation. In this article, we define this new field. First, we review ..."

review the "Grid problem," which we define as flexible, secure, coordinated resource sharing among dynamic collections of individuals, institutions, and resources---what we refer to as virtual organizations. In such settings, we encounter unique authentication, authorization, resource access

The implementation of the cilk-5 multithreaded language

by Matteo Frigo, Charles E. Leiserson, Keith H. Randall - In PLDI ’98: Proceedings of the ACM SIGPLAN 1998 conference on Programming language design and implementation , 1998
"... The fth release of the multithreaded language Cilk uses a provably good \work-stealing " scheduling algorithm similar to the rst system, but the language has been completely re-designed and the runtime system completely reengineered. The eciency of the new implementation was aided by a clear st ..."

-rst " principle has led to a portable Cilk-5 im-plementation in which the typical cost of spawning a parallel thread is only between 2 and 6 times the cost of a C function call on a variety of contemporary machines. Many Cilk pro-grams run on one processor with virtually no degradation compared

Executive Compensation

by Kevin J. Murphy , 1999
"... This paper summarizes the empirical and theoretical research on executive compensation and provides a comprehensive and up-to-date description of pay practices (and trends in pay practices) for chief executive officers (CEOs). Topics discussed include the level and structure of CEO pay (including de ..."

A Survey of active network Research

by David L. Tennenhouse, Jonathan M. Smith - IEEE Communications , 1997
"... Active networks are a novel approach to network architecture in which the switches of the network perform customized computations on the messages flowing through them. This approach is motivated by both lead user applications, which perform user-driven computation at nodes within the network today, ..."

, the routers or switches of the network perform customized computations on the messages flowing through them. For example, a user of an active network could send a “trace ” program to each router and arrange for the program to be executed when their packets are processed. Figure 1 illustrates how the routers

Convex Analysis

by R. Tyrrell Rockafellar , 1970
"... In this book we aim to present, in a unified framework, a broad spectrum of mathematical theory that has grown in connection with the study of problems of optimization, equilibrium, control, and stability of linear and nonlinear systems. The title Variational Analysis reflects this breadth. For a lo ..."

was the exploration of variations around a point, within the bounds imposed by the constraints, in order to help characterize solutions and portray them in terms of ‘variational principles’. Notions of perturbation, approximation and even generalized differentiability were extensively investigated. Variational theory

Graphical models, exponential families, and variational inference

by Martin J. Wainwright, Michael I. Jordan , 2008
"... The formalism of probabilistic graphical models provides a unifying framework for capturing complex dependencies among random variables, and building large-scale multivariate statistical models. Graphical models have become a focus of research in many statistical, computational and mathematical fiel ..."

Composable memory transactions

by Tim Harris, Mark Plesko, Avraham Shinnar, David Tarditi - In Symposium on Principles and Practice of Parallel Programming (PPoPP , 2005
"... Atomic blocks allow programmers to delimit sections of code as ‘atomic’, leaving the language’s implementation to enforce atomicity. Existing work has shown how to implement atomic blocks over word-based transactional memory that provides scalable multiprocessor performance without requiring changes ..."

with less than 50 % overhead over a non-thread-safe baseline. We support long atomic blocks containing millions of shared memory accesses with a 2.5-4.5x slowdown. Categories and Subject Descriptors D.3.3 [Programming Languages]:

Sketchpad: A man-machine graphical communication system

by Ivan Edward Sutherland , 2003
"... The Sketchpad system uses drawing as a novel communication medium for a computer. The system contains input, output, and computation programs which enable it to interpret information drawn directly on a computer display. It has been used to draw electrical, mechanical, scientific, mathematical, and ..."

Understanding Code Mobility

by Alfonso Fuggetta, Gian Pietro Picco, Giovanni Vigna - IEEE COMPUTER SCIENCE PRESS , 1998
"... The technologies, architectures, and methodologies traditionally used to develop distributed applications exhibit a variety of limitations and drawbacks when applied to large scale distributed settings (e.g., the Internet). In particular, they fail in providing the desired degree of configurability, ..."

Ptolemy: A Framework for Simulating and Prototyping Heterogeneous Systems

by Joseph Buck, Soonhoi Ha, Edward A. Lee, David G. Messerschmitt , 1992
"... Ptolemy is an environment for simulation and prototyping of heterogeneous systems. It uses modern object-oriented software technology (C++) to model each subsystem in a natural and efficient manner, and to integrate these subsystems into a whole. Ptolemy encompasses practically all aspects of design ..."
