Phoenix++ is a shared memory implementation of MapReduce that can leverage multicore architectures. As a result, it is a very useful way to introduce students to MapReduce, and demonstrate speedup with the paradigm. This module provides a gentle introduction to MapReduce and the Phoenix++ MapReduce framework. Students trace through a simplified version of the the word_count application provided with Phoenix++, and complete simple exercises to benchmark and modify the code.
