This paper introduces Exdasy, a user-friendly and extendable software tool for partitioning unstructured meshes and mapping mesh partitions to parallel computers. Ex-dasy was designed to meet the increasing demands to today's data distribution systems, which are posed by the variety of mesh computations, the ongoing development of distribution algorithms(More)
On distributed-memory systems, the quality of the data distribution has a crucial impact on the eeciency of the computation. Sophisticated visualization of large in-core and out-of-core data, and steering capabilities of the debugging system sig-niicantly reduce program development cycle, especially for irregular applications. In this paper we present an(More)
