Parallel algorithms for dynamic shortest path problems

by Ismail Chabini, Sridevi Ganugapati - International Transactions in Operational Research , 2002
"... The development of intelligent transportation systems (ITS) and the resulting need for the solution of a variety of dynamic traffic network models and management problems require faster-than-real-time computation of shortest path problems in dynamic networks. Recently, a sequential algorithm was dev ..."

complexity can be discovered. Consequently, in order to derive algorithms to solve all-to-one shortest path problems in dynamic networks, one would need to explore avenues other than the design of sequential solution algorithms only. The use of commercially-available high-performance comput-ing platforms

Saluki: a High-Performance Wi-Fi Sniffing Program

by Keren Tan, David Kotz
"... Abstract—Building a campus-wide wireless LAN measurement system faces many efficiency, scalability and security challenges. To address these challenges, we developed a distributed Wi-Fi sniffing program called Saluki. Compared to our previous implementation and to other available sniffing programs, ..."

and the back-end server was secured using 128-bit encryption; and (4) the traffic load on the backbone network was reduced to only 30 % of that in our previous implementation. In this paper, we introduce the design and the implementation details of this high-performance sniffing program, along with preliminary

Preference SQL -- Design, Implementation, Experiences

by Werner Kießling, Gerhard Köstler , 2002
"... Current search engines can hardly cope adequately with fuzzy predicates defined by complex preferences. The biggest problem of search engines implemented with standard SQL is that SQL does not directly understand the notion of preferences. Preference SQL extends SQL by a preference model based on st ..."

Characterizing and Evaluating Desktop Grids: An Empirical Study

by Derrick Kondo, Michela Taufer, Charles L. Brooks III, Henri Casanova, Andrew A. Chien - IN PROCEEDINGS OF THE INTERNATIONAL PARALLEL AND DISTRIBUTED PROCESSING SYMPOSIUM (IPDPS’04 , 2004
"... Desktop resources are attractive for running compute-intensive distributed applications. Several systems that aggregate these resources in desktop grids have been developed. While these systems have been successfully used for many high throughput applications there has been little insight into the d ..."

MTC emphasizes using many computing resources over short periods of time to accomplish many computational tasks (i.e. including both dependent and independent tasks), where the primary metrics are measured in seconds. MTC has already proved successful in Grid
