We probabilistically model dynamic packet routing on unbuuered 2-D and 3-D toroidal networks. We consider shortest-path routing with packet loss and retrans-missions versus a newly proposed all-link busy (ALB) hot-potato routing strategy with packet deeections. Computations of the sustained packet generating rate, node throughput, and average packet latency indicate that the proposed ALB strate...

* Dr. Rosen is with the Naval Air Warfare Center, Aircraft Division, Warminster, PA Abstract A critical factor in the design of any parallel processing computer system is the interconnection network between processors. Latency, throughput and other network factors weigh heavily on the performance of any parallel program. In this paper, the average latency and sustained throughput for a ten-node...

Jei-Tun Wu Department of Psychology National Taiwan University, Taiwan, R.O.C. Abstract This paper proposes two experiments to examine the effects of human head movement and latency compensation in 3D sound localization. There are two hypotheses, the first hypothesis is that through the computer simulation of 3D sound, dynamic head movement can help in the localization of sound in space, as com...

The University of Waterloo participated in the Temporal Summarization Track at TREC 2013 and submitted 8 runs for the Sequential Update Summarization Task. Methods like query likelihood ranking, pseudo relevance feedback, BM25 and cosine similarity, as well as, algorithms for passage retrieval and term expansion using distributional similarity to a set of seed words, were used for returning rel...

In this paper, we propose a novel compact BDD structure, called Non-crossing ordered BDD (NCOBDD), that can be mapped directly to a regular circuit structure. Compared with other BDD-based regular structures, NCOBDDmapped circuits reduce the costs of area, power and latency, while preserving the regularity of the structure. We also present an algorithm that uses a top-down level-by-level sweep ...

In the current experiment, we used the saccadometric test to study the effect of a single therapeutic dose of methadone on the integrity of cortico-subcortical brain functioning. In this prospective study, we used the Saccadometer System (Advanced Clinical Instrumentation, Cambridge, UK). The saccadometric test was performed before and 1.5 hours after methadone dosing. We analyzed the following...

The latency-associated transcript (LAT) gene the only herpes simplex virus type 1 (HSV-1) gene abundantly transcribed during neuronal latency, is essential for efficient in vivo reactivation. Whether LAT increases reactivation by a direct effect on the reactivation process or whether it does so by increasing the establishment of latency, thereby making more latently infected neurons available f...

Switch design for interconnection networks plays an important role in the overall performance of multiprocessors and computer networks. In this paper, a new switch design, namely FC-CB, is proposed that offers low average message latency and high throughput over a wide range of input workloads. The FC-CB switch incorporates wormhole routing and virtual channels with a full crossbar connection. ...

Abstmct-VLSI communication networks are wire-limited. The cost of a network is not a function of the number of switches required, but rather a function of the wiring density required to construct the network. This paper analyzes communication networks of varying dimension under the assumption of constant wire bisection. Expressions for the latency, average case throughput, and hot-spot throughp...
