A parallel advancing front scheme has been developed. The domain to be grid
ded is first subdivided spatially using a relatively coarse octree. Boxes a
re then identified and gridded in parallel. A scheme that resembles closely
the advancing front technique on scalar machines is recovered by only cons
idering the boxes of the active front that generate small elements. The pro
cedure has been implemented on the SGI origin class of machines using the s
hared memory paradigm. Timings for a variety of cases show speedups similar
to those obtained for flow codes. The procedure has been used to generate
grids with tens of millions of elements. Copyright (C) 2001 John Wiley & So
