Abstract

Multi-physics HPC applications with mixed discretization schemes, adaptive unstructured meshes, and parallel distributed data sets have inherent complexity that must be managed. Design concepts embedded in the mesh data structures will either segregate complexity from, or compound complexity throughout, such applications. A recent research effort at Sandia National Laboratories is focusing on performance modeling and analysis of these complex applications. For this effort portable compact mini-applications (a.k.a. "dwarf" applications) are being developed to approximate the performance of corresponding "real" applications. For one of these mini-applications a new, fully functional, component has been developed for parallel, heterogeneous, and dynamic unstructured meshes (phdMesh). This component will be made available at software.sandia.gov. A decade of experience with a variety of target applications has led to the concise concepts, object oriented design, and minimalistic application programmer interface (API) of the phdMesh component.
