The DAGH (Distributed Adaptive Grid Hierarchy) data-management infrastructure for parallel adaptive mesh refinement techniques consists of two components:

  • A set of programming abstractions in which computations on dynamic hierarchical grid structures are directly implementable. The appropriate programming abstractions are a hierarchy of scalable distributed dynamic grids and a set of operations on this grid hierarchy. The operations include creation, partitioning, computations on the grid such as stencil operations, communication among grid partitions at a single level and communication among grids at different levels of the hierarchy.
  • A set of distributed dynamic data-structures that support the implementation of the abstractions in parallel execution environments and preserve efficient execution while providing transparent distribution of the grid hierarchy across processing element execution environment.
