### OpenCL Parallel Reduction Example ###

===========================================================================

DESCRIPTION:

This example shows how to perform an efficient parallel reduction using OpenCL.

Reduce is a common data parallel primitive which can be used for variety

of different operations -- this example computes the global sum for a large

number of values, and includes kernels for integer and floating point vector

types.

Note that the .cl compute kernel file(s) are loaded and compiled at

runtime.  The example source assumes that these files are in the same 

path as the built executable.

For simplicity, this example is intended to be run from the command line.

If run from within XCode, open the Run Log (Command-Shift-R) to see the 

output.  Alternatively, run the applications from within a Terminal.app 

session to launch from the command line.
