The Lab

As our name implies, our research centers around Dependable Parallel Computers and Networks. Our research in Fault Tolerance and Reliability result in the "Dependable" part of our name. Our research also includes "Parallel Computers", Computer Architecture and "Networks". This Lab is led by Professor Arun K. Somani and Professor James Meditch.

Our research into dependability includes issues in reliability, dependability and fault tolerance in all aspects of computer systems and networks. Currently we have active work occurring in the area of Fault Propagation in Cache Memory to determine effective protocols for detecting and correcting faults in cache memories.

We are building a comprehensive reliablity analysis tool ,HIMAP, the HIerarchical Modeling and Analysis Package.

Our research into Parallel Computers and Parallel Algorithms ranges from interconnection networks and architecture to efficient partitioning methods for parallel algorithms. Currently we have ongoing research in the PROTEUS Parallel Computer, a machine designed and implemented in this lab in conjunction with the Applied Physics Lab here at the University of Washington. This machine is used for applications such as real time Imaging, Visualization, and Rendering in both 2 and 3 dimensions.

Our research into networks is far ranging. Topics range from Video Transmission in ATM Networks, in which we try to characterize traffic sources in ATM networks and address the issues of bandwidth allocation, to High Speed Networks in which we address issues in multicasting, and other inter-networking issues. Another topic of research is Optical Networking. Currently, we are looking at certain issues in wavelength-routing networks.

Currently, 9 Phd students and 3 MS students are working in the laboratory. The DPCNL computer resources consist of 9 Sun SparcStations, a Mac IICi, a Gateway Pentium 60, and a configuration of Proteus parallel machine (12 PE). In addition we also have access to a 32 PE Proteus, a 16 node Intel Paragon machine, and a 53 node KSR at the University of Washington.

We also have access to video digitizers and sources of video streams. The Proteus (Intel i860-based) parallel processor can also be used for processing of information at high speed and to generate realistic input data streams. Our latest acquisition is a 4-port ATM switch from Fore Systems. The switch is being used by the ATM group for research in the field of Video Image transfer and analysis. The switch will also be used to demonstrate its role in an all-optical network backbone in the new EE/CS/CSE building.
