Parallel algorithms for corner stitching

Corner stitching is the underlying data structure that is used to represent rectangular objects in interactive VLSI layout editing systems such as Magic and Tailor. In this paper we develop efficient algorithms for basic corner stitching operations under the message-passing paradigm. These algorithms were implemented using C and PVM on a distributed network composed of SUN workstations. Experimental results show that significant speed-ups were obtained. © 1998 John Wiley & Sons, Ltd.
