quad_mpi, a C++ code 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.

quad_mpi is available in a C version and a C++ version and a FORTRAN90 version and a Python version.
