GEMV Tutorial 5: Multiple PEs
=============================

The power of the Wafer-Scale Engine lies in its hundreds
of thousands of processing elements.
Now that we've covered some basics for writing a complete
program using a single PE,
let's create our first program using multiple PEs.

Now that we've introduced multiple PEs into our program,
instead of duplicating our GEMV problem between them,
let's actually distribute the work for computing a single GEMV.
