Abstract - In this paper we present two approaches for parallel out-of-core mesh generation. The first approach is based on a traditional prioritized page replacement algorithm using prioritized version of accepted LRU replacement scheme proposed by Salmon et al. for n- body calculations. The second approach is based on the percolation model proposed for the HTMT petaflops design. We evaluate both approaches using the parallel constrained Delaunay mesh generation method. Our preliminary data suggest that for problem sizes up to half a billion element meshes the traditional approach is very effective. However for larger problem sizes (in the order of billions of elements) the traditional approach becomes prohibitively expensive, but it appears from our preliminary data that the non-traditional percolation approach is a good alternative.
