Research Overview

Techniques for parallel processing are absolutely essential for achieving dramatic improvements in computer system performance. Therefore, it is necessary to conduct a broad range of research, covering everything from hardware architecture to operating systems, programming languages and applications, in order to establish techniques for integrated parallel computer systems. In the last few years, we have mainly been focused on "cluster systems," consisting of multiple personal computers (PCs) or workstations (WSs) interconnected via a network. We have built such systems, evaluated their performance, developed parallel programs, and conducted research on support systems. By designing and developing actual systems, and comparing them with systems using different parallel processing methods such as shared-memory multiprocessors, we qualitatively and quantitatively examine the various tradeoffs in terms of hardware and software for achieving efficient parallel processing systems.
