PARAMESH: A Parallel, Adaptive Mesh Refinement Toolkit and Performance of the ASCI/FLASH code
Abstract
We describe a package of routines known as PARAMESH which enables a user to easily convert an existing serial, uniform grid code to a parallel code with adaptive-mesh refinement. The package does this through the use of a block-structured form of AMR in combination with a tree data structure for distributing blocks to processors. We also describe some of the applications which have been developed using PARAMESH with special emaphasis on the ASCI/FLASH code. Performance results are also discussed for a variety of parallel architectures.
