This book constitutes the refereed proceedings of 11 IPPS/SPDP '98 Workshops held in conjunction with the 13th International Parallel Processing Symposium and the 10th Symposium on Parallel and Distributed Processing in San Juan, Puerto Rico, USA in April 1999. The 126 revised papers presented were carefully selected from a wealth of papers submitted. The papers are organised in topical sections on biologically inspired solutions to parallel processing problems: High-Level Parallel Programming Models and Supportive Environments, Biologically Inspired Solutions to Parallel Processing, Parallel and Distributed Real-Time Systems, Run-Time Systems for Parallel Programming, Reconfigurable Architectures, Java for Parallel and Distributed Computing, Optics and Computer Science, Solving Irregularly Structured Problems in Parallel, Personal Computer Based Workstation Networks, Formal Methods for Parallel Programming, Embedded HPC Systems and Applications.
