Ulrich Huber: A Scalable Mesh Format for Parallel Unstructured Meshes in Scientific Applications

A common goal of all scientific applications is an optimized workflow and good scalability. Therefore the code of such applications as well as the used file formats for initialization need to be optimized, both in time consumption as well as scalability. PXDMF, a mesh format for parallel unstructured meshes providing small file sizes, scalability and small generation and initialization times, is presented in this talk. The format is not tailored to a specific use case, but supports various topologies for cells and can handle additional data, needed by using applications. An initialized mesh is stored in the library within a traversable data structure, by which applications can access all data. Furthermore PXDMF provides all required information, enabling applications to establish a communication structure. Finally PXDMF is compatible to visualization tools, such as ParaView and VisIt and supports homogeneous as well as heterogeneous clusters. All this makes PXDMF applicable to a broad spectrum of scientific applications, using unstructured partitioned meshes, to solve their scenarios.
