Unstructured mesh preprocessing library hm4PreprocessorLib

This paper contains the description of the parallel library hm4PreprocessorLib. The library includes routines for the unstructured meshes and graphs processing during initialization of parallel computing experiments. We present the results of the mesh processing, comprising $230\cdot10^6$ elements such as a tetrahedron, a prism, a pyramid and a hexahedron with the launch of $336$ MPI-processes.
