SCVT_MPI
Parallel Program for Centroidal Voronoi Tessellations on Spheres

SCVT_MPI is a C++ program which carries out a procedure that produces Centroidal Voronoi Tessellations (CVT's) on the surface of a sphere.

A CVT is a kind of mesh. Such meshes can be used for weather or climate modeling on the Earth's surface, for instance.

The program uses Jonathan Shewchuk's triangle library, which can triangulate a set of points in the plane.

The program uses the boost library of high-quality arithmetic procedures, in particular, it refers to the boost mpi and boost serialization libraries.

The program relies on the boost mpi library to implement the parallel execution of the algorithm.

The program relies on the boost serialization library to encode a C++ structure as a sequence of bytes that can be recorded in a file or transmitted as a message, which can then be decoded by a receiving program to recover the original C++ structure.
