“…ADH evolves the mesh resolution to efficiently capture dynamic boundary conditions, forcing functions, and sharp fronts. ADH runs on parallel architectures because problems of interest have high memory and/or run-time requirements [9,24]. This paper describes the mesh refinement and unrefinement algorithms used to control mesh evolution in ADH.…”

Problems in hydrology frequently have moving fronts and dynamic driving mechanisms such as wells. Since the location of important features changes during a simulation, accurate modeling requires uniformly fine resolution or the ability to change resolution during the simulation. We will describe an algorithm for refinement and unrefinement of tetrahedral/triangular meshes that has been implemented in the adaptive hydrology (ADH) code. The codes including the refinement/unrefinement algorithms are implemented in parallel to accommodate problems with large run time and memory requirements. In this paper, we describe the parallel, adaptive grid algorithm used in ADH and show the resulting grids from some example problems.

An asynchronous communication library for accessing and managing dynamic hash tables over a network of Symmetric Multiprocessors (SMP) is presented. A blocking factor is shown experimentally to reduce the variance of the wall clock time. It is also shown that remote accesses to a distributed hash table can be as effective and scalable as the one-sided operations of the low-level communication middleware on an IBM SP.
