Call for Papers Special Issue of the Journal of Parallel and Distributed Computing (JPDC) on Workstation Clusters and Network-based Computing Papers are solicited for a special issue of the Journal of Parallel and Distributed Computing (JPDC) on workstation clusters and network-based computing to be published in February 1997. A new trend in parallel processing has emerged to use ``clusters of workstations'' over Local Area Networks (LANs) as cost-effective parallel computing platforms. This new trend is gaining popularity to establish a new parallel processing paradigm: ``network-based computing''. Since the LAN technology was not initially developed for parallel processing, the communication overheads between workstations are still quite high. This has forced severe constraints on obtaining performance gains in workstation clusters. Many research groups from academia, industry, and research labs have currently engaged in deriving novel hardware and software solutions to alleviate these bottlenecks. This special issue is targeted to include a set of original articles that represent the state-of-the-art in designing workstation clusters and supporting network-based computing. Results of both theoretical and practical significance will be considered. Topics of interest include, but not limited to: architectural and operating system supports for achieving fast communication and synchronization; network interface design; implementation of efficient messaging layers; LAN interconnection with high-speed switches; characterization of communication and synchronization traffic; collective communication support; experience in implementing MPI and HPF; data distribution and load balancing; supporting shared memory paradigm; and performance evaluation and benchmarking. Authors should follow the JPDC manuscript format as described in the ``Information for Authors'' at the end of each issue of JPDC. Five copies of complete double-spaced manuscripts should be sent to either one of the two co-guest editors by March 1, 1996. Authors will be notified of the final publication decision by August 1, 1996. Only original, unpublished work will be considered; manuscripts resembling any previously published work in a journal are unacceptable. Co-Guest Editors Dr. Dhabaleswar K. Panda Dr. Lionel M.
