These scripts were written as a learning exercise for me to learn OpenCL. 
They were inspired by the excellent _OpenCL Programming Guide_ 
by authors including Apple's Aaftab Munshi, AMD's  Benedict Gaster, 
Intel's Timothy Mattson, NVIDIA's James Fung published July 2011

I've been a fan of Andreas Kloeckner's work since 2009 and PyCUDA.  
PyOpenCL provides a complete set of features for OpenCL 1.1(as of August 2011). 
PyOpenCL provides a fantastic degree of brevity, starkly contrasted to 
the burdensome boilerplate typically required in OpenCL applications written 
with the C API.  I don't exploit all of the possible brevity, but during my learning
phase, I lean on the pythonic wisdom that explicit is better than implicit.  

This doesn't mean that I always go for the lengthiest solution possible, 
but I'm attempting to strike what feels like a natural middle ground 
between the possible verbosity(sometimes good for learners) and ease of coding(good for everyone).

An example of this is that I launch kernels by calling them as methods to the 
OpenCL program object rather than setting their arguments manually and
enqueuing the execution.

    Hello World
        Most of these scripts were written for execution on vertex, one of the most 
        powerful on the UAB hospital network with a dual quad-core Xeon CPU and 
        two NVIDIA GPUs, a Tesla 1060 and one minimal one for the display. 

        There are thus two OpenCL platforms to choose from. Enumerating and querying
        the devices is explored followed by a simple kernel for vector vector addition.
        
    laplace
        Since undergrad, i've repeatedly used a simple Jacobian iteration solution to the laplace 
        equation in order to learn about programming.  This method provides a nice balance
        between a toy learning problem and one with actual use in scientific computing. 
        I implement a steady state solver in two dimensional space using constants
        provided in Chapra's textbook: _Numerical Methods for Engineers_ p. 856
