DAGH 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.

However, g77 seems not working very well for DAGH. Software/Hardware Requirements: MPI, xgraph (for visulaization), HDF/rnpl (for IO).
