Abstract: I will describe the Screen Saver Science project (SSS), a project aimed at harnessing the unused processing power of desktops, workstations, and other processors, using nothing more than a thin software layer on top of the technologies available in Java, Jini, and JavaSpaces (JJJ). I will first describe the basics of the JJJ technologies and the basic SSS infrastructure. I will then outline the parallel programming model this environment will expose to the user and the general characteristics of applications that will best fit this model. Many questions remain on the feasibility of this type of system as a production quality scientific computing environment, such as computing and communications performance and security, however I am optimistic that these issues will soon be solved or minimized. The ultimate goal of this project is to make available, here at NIST, a scientific computing resource capable of handling very large computations that may not be suitable for any other available computing resource. To place this project in context, comparisons will be made to related topics such as Grid computing, Peer-to-Peer computing, and High-Throughput computing (e.g. SETI@Home).
