Javelin: Internet-based parallel computing using Java

Abstract

Java offers the basic infrastructure needed to integrate computers connected to the Internet into a seamless parallel computational resource: a flexible, easily-installed infrastructure for running coarsegrained parallel applications on numerous, anonymous machines. Ease of participation is seen as a key property for such a resource to realize the vision of a multiprocessing environment comprising thousands of computers.We present Javelin, a Java-based infrastructure for global computing. The system is based on Internet software technology that is essentially ubiquitous: Web technology. Its architecture and implementation require participants to have access only to a Java-enabled Web browser. The security constraints implied by this, the resulting architecture, and current implementation are presented. The Javelin architecture is intended to be a substrate on which various programming models may be implemented. Several such models are presented: A Linda Tuple Space, an SPMD programming model with barriers, as well as support for message passing. Experimental results are given in the form of micro-benchmarks and a Mersenne Prime application that runs on a heterogeneous network of several parallel machines, workstations, and PCs.

A large-scale study on the usage of Java’s concurrent programming constructs

“…Another limitation is that the Java programming language has a number of external libraries, and several of them are related to concurrent/parallel programming (Christiansen et al, 1997;Ferrari, 1997). In fact, the java.util.concurrent package was an external library for a long time, until the Java Community Process 11 included it in version 1.5 of the language.…”

Visualizing the research on pervasive and ubiquitous computing

“…Its labeling term is called ''internet-based parallel computing.'' One of its citing papers called ''Javelin: internet-based parallel computing using java'' written by Christiansen et al (1997), Schmalstieg et al (2000) mainly used java to construct the internet-based parallel computing and complete application service. The third largest cluster (#1), with 16 members, is labeled as ''wide web'' and one of its active citers designed a system called ''teleweb'' for people to have access to the World Wide Web anytime and anywhere with the purpose of getting work done.…”

Computing on large-scale distributed systems: XtremWeb architecture, programming models, security, tests and convergence with grid

“…Due to its high attractiveness, cycle stealing has been studied in many research projects like Condor [33], Glunix [26] and Mosix [8] to cite a few. A first approach to cross administration domains was proposed by Web computing projects such as Jet [37], Charlotte [9], Javeline [15], Bayanihan [44], SuperWeb [4], ParaWeb [13] and PopCorn [35]. These projects have emerged with Java taking benefit of the virtual machine properties: high portability across heterogeneous hardware and operating systems, large diffusion of virtual machine in Web browsers and a strong security model associated with bytecode execution.…”
