High Performance Computers — A status report
نویسنده
چکیده
Some years ago the supercomputer landscape changed dramatically: the supremacy of vector processorbased systems had to give way to machines built from Commodity Of-The-Shelf (COTS) products that promised to deliver a better price-performance ratio. In addition cheap Beowulf clusters emerged and are massively employed in laboratories all over the world. We discuss some reasons for this change and also address questions like: Is there still room for computer architecture research? Is there still value in large systems as built in the ASCI initiative in the USA as opposed to clusters? We will review the present status of the supercomputer field and comment on the (rather limited) architectural range that is offered today. Furthermore, we will discuss some of the latest developments in the field and how they may impact on the machines to come.

Computer-related anxiety: examining the impact of technology-specific affect on the performance of a computerized neuropsychological assessment measure.
This study was conducted to examine the effect of impairment status and computer-specific anxiety on the performance of a computerized neuropsychological assessment measure. Computer related anxiety was measured using a standardized self-report measure tapping anxiety specific to computers and technology. Outcome on this measure was compared with error scores and response timing variables on a ...
متن کاملParallel Spatial Pyramid Match Kernel Algorithm for Object Recognition using a Cluster of Computers
This paper parallelizes the spatial pyramid match kernel (SPK) implementation. SPK is one of the most usable kernel methods, along with support vector machine classifier, with high accuracy in object recognition. MATLAB parallel computing toolbox has been used to parallelize SPK. In this implementation, MATLAB Message Passing Interface (MPI) functions and features included in the toolbox help u...
متن کاملUse of Computer and Internet in Agricultural Extension as perceived by Extension Workers
The purpose of this study was to determine computer and Internet use in agricultural extension by Extension Workers (EWs). This study used a descriptive-correlational design.Population for the study consisted of all extension workers (N= 320) in Isfahan Province, Iran. A stratified sampling technique and census was used to select EWs (n = 200). Overall, findings indicate that EWs have access to...
متن کاملHigh Performance Computer Methods Applied to Predictive Space Weather Simulations
Taking advantage of the advent of massively parallel computers, sophisticated solution-adaptive techniques, and recent fundamental advances in basic numerical methods we have developed a high performance, adaptive-scale MHD code capable of resolving many of the critical processes in the Sun–Earth system which range over more than nine orders of magnitude. The development of such models are of i...
