GEMV Tutorial 4: Parameters
===========================

We've written a complete program that copies data to and from the
device, but both our host and device still need to define the
dimensions ``M`` and ``N``.
Now we introduce compile time parameters to set ``M`` and ``N``
while compiling our code, and show how our host code can read
these values from the compile output.

We've gone over some basics for writing a complete program
using a single PE.
Now let's move on to using multiple PEs.
