QUAD_MPI\ Quadrature using MPI {#quad_mpi-quadrature-using-mpi align=”center”} ====================

---

QUAD_MPI is a C++ program which approximates an integral using a quadrature rule. The computation is done in parallel by using MPI.

The latest versions of MPI no longer support the special C++ MPI bindings, so the examples given here have reverted to using the C MPI bindings.
