MPI Documentation

The manual pages are split into four categories; we recommend that you begin with basic functionality and then gradually explore more sophisticated library features.

• Beginner - Basic usage

• Intermediate - Setting options for algorithms and data structures

• Advanced - Setting more advanced options and customization

• Developer - Interfaces intended primarily for library developers
