Search engines require computers with high computation resources for processing to crawl web pages and huge data storage to store billions of pages collected from the World Wide Web after parsing and indexing these pages. The indexer is one of the main components of the search engine that come intermediate between the crawler and the searcher. Indexing is the process of organizing the collected...

We are developing a compiler that translates ordinary MATLAB scripts into code suitable for compilation and execution on parallel computers supporting C and the MPI message-passing library. In this paper we report the speedup achieved for several MATLAB scripts on three diverse parallel architectures: a distributed-memory multicomputer (Meiko CS-2), a symmetric multiprocessor (Sun Enterprise Se...

As a tendency to use new technologies, gadgets such as laptop computers are becoming more popular among students, teachers, businessmen and office workers. Today laptops are a great tool for education and learning, work and personal multimedia. Millions of men, especially those in the reproductive age, are frequently using their laptop computers on the lap (thigh). Over the past several years, ...

In this paper we present the design and implementation of a parallel system for interactive segmentation and visualization of three-dimensional medical images which is distributed on a heterogenous cluster of workstations or personal computers. All image processing functions are multithreaded to use the advantages of symmetric multiprocessors. Its platform-independence is achieved using standar...

There are several existing concepts and solutions that are intended for coupling several parallel computers in means of running a single MPI application on top of them. PACX–MPI [1] is one of them that relies on existing MPI libraries on the respective machines. This paper discusses several facts and aspects for using PACX–MPI in an Cluster–of–Clusters (CoC) environment.

While the number of computers in the classroom continues to increase and tremendous support for technology integration exists in government, business, and academia, a major discrepancy exists between the level of technology use that is expected from the educators and the actual use and integration of technology in the classroom. However, effective technology integration in early childhood educa...

Recent advantages in network and workstation performance have made clustered computer systems an interesting alternative to massively parallel computers. There are many operating systems, languages, programming environments and tools, used in design, optimization and debugging of parallel programs. This article discusses briefly general issues with cluster SW tools as well as discussing some of...

We describe a method of decoupling networks for the purpose of running a simulation in parallel with each separate section executing with different time steps. The speed advantages are system-dependent, but a particular scenario where the method is applicable is studied, resulting in a speedup of more than 5 when running on a cluster of two computers.
