This is the static webpage and code for mpitutorial.com. View mpitutorial.com/about/ for guidelines on how to contribute tutorials, or feel free to open a pull request to fix any issues.

For those that simply wish to view MPI code examples without the site, browse the tutorials/*/code directories of the various tutorials. The tutorials/run.py script provides the ability to build and run all tutorial code.

The number of processes run for each of the tutorial exists within as a dictionary in run.py itself. In order to change the configurations, please edit the run.py, and then run the example that you want the arguments to run against.
