AParallelUnstructuredMeshLibrary optimized for reading large unstructured meshes, version2.

PUML2 is a parallel reader for large unstructured meshes.Currently, it supports meshes stored inHDF5, described by theXDMF format.PUML2 reads meshes in$\mathcal{O}(n + m/n)$ and requires$\mathcal{O}(n + m/n)$ memory per MPI process where$n$ is the total number of processes and$m$ the number of elements.The current implementation is limited to tetrahedral meshes but the code is prepared to support hexahedral meshes as well.

PUML2 is a C++ header-only library written in C++17.You simply copy the header files into your project and start using it.
