Implementing Parallel Adaptive Procedures for PDEs: Issues and Experiences

The numerical treatment of partial differential equations whose solutions exhibit complex behavior, such as moving fronts, shocks, and boundary layers is extremely computationally intensive. Two important ingredients in making such problems tractable are the use of adaptive methods and parallel computing. A number of difficult implementation issues arise when these two are combined together. This minisymposium will focus on these issues, including parallel mesh generation, parallel refinement and coarsening of meshes, dynamically adapting partitions of meshes across the processing units, and ensuring that the parallel overhead is kept to a minimum.
