As the size of crews continues to be reduced on modern warships, and at the same time the complexity of the tasks that warships have to handle continues to increase, the amount of computing power aboard a warship will have to increase dramatically. One of the most cost-effective ways of creating supercomputers is to cluster inexpensive off-theshelf commodity computers so that they act as a sing...

Over the past few years cluster computers have become commonplace. During that time the interconnect choices have gotten more numerous. For the early clusters the obvious choice was Fast Ethernet. However, today there are several options including Gigabit Ethernet, Myrinet, SCI and others. Which one is right for your cluster will depend on many factors including cost, cluster size, latency and ...

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...

Two new schemes for computing molecular total atomization energies (TAEs) and/or heats of formation (∆H • f) of first-and second-row compounds to very high accuracy are presented. The more affordable scheme, W1 (Weizmann-1) theory, yields a mean absolute error of 0.30 kcal/mol and includes only a single, molecule-independent, empirical parameter. It requires CCSD (coupled cluster with all singl...

Automatic text summarization has become important due to the rapid growth of information texts since it is very difficult for human beings to manually summarize large documents of texts. A full understanding of the document is essential to form an ideal summary. However, achieving full understanding is either difficult or impossible for computers. Therefore, selecting important sentences from t...

We investigate the use of a cluster of networked Apple iMac or Power Macintosh personal computers as a compute server for sequential and parallel programs, and describe our experiences with a cluster of iMacs used primarily for an undergraduate teaching laboratory. We explore the support for cluster computing ooered by the various operating systems available for the Macintosh: MacOS 8; the upco...
