PPGP - A Parallel Partitioner for Unstructured Grids and Random Particles <author>Hong Q. Ding / hding@redwood.jpl.nasa.gov <version> <abstract> Until recently, most unstructured grids/particles are first partitioned on a sequential computer and then loaded into a parallel computer. For large grids, this scheme becomes a serious bottleneck, both in the size of the grids it can handle and in the time of partitioning such a large grids on sequential computer. PPGP instead loads the entire grids first into a parallel computer and then partition the grids in a parallel fashion. This enables one to do much larger grids and speeds up the partitioning process significantly. <reference><url></url> <contact>Hong Q.
