mpi-travis

This project is a minimal template for setting up continuous integration testing of MPI projects with travis. The template demonstrates:

• Building mpich 3.2 on travis from source.
• Use of the travis container architecture for faster builds.
• Use of caching to save the mpich installation.
• Test execution with mpirun -np 4.

A more complete example including integration with cmake and ctest can be found in BeamLaser.
