Route Packets, Not Wires: On-Chip Interconnection Networks

by William J. Dally, Brian Towles , 2001
"... Using on-chip interconnection networks in place of ad-hoc global wiring structures the top level wires on a chip and facilitates modular design. With this approach, system modules (processors, memories, peripherals, etc...) communicate by sending packets to one another over the network. The structur ..."

Efficient Software-Based Fault Isolation

by Robert Wahbe, Steven Lucco, Thomas E. Anderson, Susan L. Graham , 1993
"... One way to provide fault isolation among cooperating software modules is to place each in its own address space. However, for tightly-coupled modules, this solution incurs prohibitive context switch overhead, In this paper, we present a software approach to implementing fault isolation within a sing ..."

Concurrent Constraint Programming

by Vijay A. Saraswat, Martin Rinard , 1993
"... This paper presents a new and very rich class of (con-current) programming languages, based on the notion of comput.ing with parhal information, and the con-commitant notions of consistency and entailment. ’ In this framework, computation emerges from the inter-action of concurrently executing agent ..."

agents that communi-cate by placing, checking and instantiating constraints on shared variables. Such a view of computation is in-teresting in the context of programming languages be-cause of the ability to represent and manipulate partial information about the domain of discourse, in the con

Myrinet: A Gigabit-per-Second Local Area Network

by Nanette J. Boden, Danny Cohen, Robert E. Felderman, Alan E. Kulawik, Charles L. Seitz, Jakov N. Seizovic, Wen-king Su - IEEE Micro , 1995
"... Abstract. Myrinet is a new type of local-area network (LAN) based on the technology used for packet communication and switching within "massivelyparallel processors " (MPPs). Think of Myrinet as an MPP message-passing network that can span campus dimensions, rather than as a wide-a ..."

Critical Power for Asymptotic Connectivity in Wireless Networks

by Piyush Gupta, P. R. Kumar , 1998
"... : In wireless data networks each transmitter's power needs to be high enough to reach the intended receivers, while generating minimum interference on other receivers sharing the same channel. In particular, if the nodes in the network are assumed to cooperate in routing each others ' pack ..."

as the number of nodes in the network goes to infinity. It is shown that if n nodes are placed in a disc of unit area in ! 2 and each node transmits at a power level so as to cover an area of ßr 2 = (log n + c(n))=n, then the resulting network is asymptotically connected with probability one if and only

SPINS: Security Protocols for Sensor Networks

by Adrian Perrig, Robert Szewczyk, Victor Wen, David Culler, J. D. Tygar , 2001
"... As sensor networks edge closer towards wide-spread deployment, security issues become a central concern. So far, the main research focus has been on making sensor networks feasible and useful, and less emphasis was placed on security. We design a suite of security building blocks that are optimized ..."

Convex Position Estimation in Wireless Sensor Networks

by Lance Doherty , Kristofer S. J. Pister , Laurent El Ghaoui
"... A method for estimating unknown node positions in a sensor network based exclusively on connectivity-induced constraints is described. Known peer-to-peer communication in the network is modeled as a set of geometric constraints on the node positions. The global solution of a feasibility problem fo ..."

The process group approach to reliable distributed computing

by Kenneth P. Birman - Communications of the ACM , 1993
"... The difficulty of developing reliable distributed softwme is an impediment to applying distributed computing technology in many settings. Expeti _ with the Isis system suggests that a structured approach based on virtually synchronous _ groups yields systems that are substantially easier to develop, ..."
Abstract - Cited by 572 (19 self) - Add to MetaCart
distributed operating systems have placed emphasis on communication performance, overlooking the need for tools to integrate components into a reliable whole. The communication primitives supported give generally reliable behavior, but exhibit problematic semantics when transient failures or system

Re-place-ing Space: The Roles of Place and Space in Collaborative Systems

by Steve Harrison, Paul Dourish , 1996
"... Many collaborative and communicative environments use notions of “space ” and spatial organisation to facilitate and structure interaction. We argue that a focus on spatial models is misplaced. Drawing on understandings from architecture and urban design, as well as from our own research findings, w ..."

Bullet: High Bandwidth Data Dissemination Using an Overlay Mesh

"... In recent years, overlay networks have become an effective alternative to IP multicast for efficient point to multipoint communication across the Internet. Typically, nodes self-organize with the goal of forming an efficient overlay tree, one that meets performance targets without placing undue burd ..."
