convex_hull_sample [S] [M[:N]] [-v]

S is the number of points (problem size). M:N are a range of numbers of threads to be used. Use the -v option to turn on verbose output.

To run a short version of this example, e.g., for use with Intel® Threading Tools:

Build a debug version of the example (see the build instructions).
Run it with a small problem size and the desired number of threads, e.g., convex_hull_sample 4 500000.
