Free upgrade of computer power with java, web-base technology and parallel computing

This paper presents inexpensive ways to implement parallel computing which will make tremendous impact on many areas of computer application, Any one has knowledge of Java and more than two computers can solve their old problems with new technology by use of parallel computing. However, parallel computers are still expensive today and thus only very large companies and rich universities can afford the use of parallel computing technologies to solve their complex problems. Special training is also required for programmers who write parallel programs. With the advancement of Java and Internet/Intranet technologies, small to medium size companies can now also use the benefit of parallel computing to solve computation intensive task with their microcomputers. Most companies have a large number of microcomputers/workstations and these computers are already connected to Internet/Intranet. Additional cost for hardware and software installation is not required to prepare these computers for parallel computing. This paper presents two simple models to use ordinary microcomputers, workstations for parallel computing and a brief tutorial on the concept. Experiments are conducted to test the performance of the parallel systems. The performance of these two models will be compared. The advantages and limitations of these models are also discussed in this paper
