Abstract

Parallel mask verification algorithms have been developed for the Connection Machine, a massively parallel processor with up to 64K processors. We discuss the design and implementation of algorithms for several essential primitives: generation of completely-intersected mask data, mask-to-mask Boolean operations, labeling of connected regions, and identification of width and spacing violations. Performance results from experiments on a 16K-processor machine are presented. Speedups between 40 and 240 over a VAX 11/785 have been measured.
