Collective communication allows efficient communication and synchronization among a collection of processes, unlike point-to-point communication that only involves a pair of communicating processes. Achieving high performance for both kernels and full-scale applications running on a distributed memory system requires an efficient implementation of…

This paper reviews the research on the disruptive and transformative potential of newly-emerging cloud-based pedagogies. It takes into consideration the extent to which Cloud Computing can be leveraged to disseminate and scale web-based applications within and across learning contexts. It examines ideas from current literature in Web 2.0- and…

As news outlets create headlines such as "A Cloud & A Prayer," "The Cloud Is the Computer," and "Leveraging Clouds to Make You More Efficient," many readers have been left with cloud confusion. Many definitions exist for cloud computing, and a uniform definition is hard to find. In its most basic form, cloud…

Mass storage refers to the variety of ways to keep large amounts of information that are used on a computer. Over the years, the removable storage devices have grown smaller, increased in capacity, and transferred the information to the computer faster. The 8" floppy disk of the 1960s stored 100 kilobytes, or about 60 typewritten, double-spaced…

This article discusses the importance of saving data safely. Suggestions include making backup copies of all important computer documents; frequently hitting the Ctrl-S keys to save current documents to the hard disk; periodically save a backup copy to a floppy disk; periodically saving a copy through the Internet to an offsite backup disk; and…

Electronic examination systems, which include Internet-based system, require extremely complicated installation, configuration and maintenance of software as well as hardware. In this paper, we present the design and development of a flexible, easy-to-use and secure examination system (e-Test), in which any commonly used computer can be used as a…

Discusses the pricing of computer services. (PF)

Discusses problems resulting from incompatible computer systems. Outlines how to make interchange of data possible between systems. Concludes that with the popularity of microcomputers increasing, learning how to make information compatible between systems is essential. (BSR)

Describes a recently developed new dimension in management and educational concepts. (Author)

What's the worst thing that can happen to a computer? Worse than a hard disk crash, virus infection, spare assault, denial-of-service attack, hacker take-over, fire, flood or some other human, mechanical or natural disaster is a faulty backup when it is really needed. If the computer blows up, as long as the data is backed up securely, it can be…

This document discusses the importance of data-quality and presents three simple steps that can help lay the framework for an over all data-quality strategy. The first step is to ask some rather simple questions, such as: (1) How much data does the organization have, how fast is it creating new data, and how many redundant copies are there?; and…

The Mini-Computer is compared with the general purpose computer. On a performance basis the Mini-Computer shows several interesting comparisons with the System 360 computer. The Mini-Computer core cycle, instruction execution speeds, and disc operating speeds are quite similar to the much larger 360-30 and 40 while its magnetic tape speeds are…

A disk sector utility program (called TRAX) was designed and developed since a computer aid capable of inspecting and modifying the byte data on a disk platter, independent of any other program or system, was not commercially available. This report: (1) provides an overview of the TRAX system; (2) briefly describes the major system options; and…

The paper descibes a compact and highly efficient disk file management system responsible for the management and allocation of space on moving head disk drives in a medium-scale time-sharing system. The disk file management system is a major component of the Experimental Time-Sharing System (ETSS) developed at the Learning Research and Development…

This paper describes the efforts of the Program on Teacher Effectiveness of the Stanford Center for Research and Development in Teaching to survey and catalog available teacher training products. It is stated that the project developed from the program's own need to identify potential products which could be incorporated into the program's…
