+This will result in some comparison metrics between the OpenCL implementation (if installed - should revert to using ctypes if no OpenCL is installed) and a plot of the two calculations and a comparison plot; ie, three plots. If you do not see three plots, see the note on OpenCL issues at the bottom of the page.

 Once compare and the unit test(s) pass properly and everything is done, commit your new model to the repo and then edit the models table at [http://trac.sasview.org/wiki/ListofModels] to indicate that the conversion is complete.

+'''OPENCL ISSUES'''
+If the compare.sh modelname -1d test only generates one plot instead of three, or the compare.sh modelname -2d test complains that there is "No module named pyopencl", then you may not have OpenCL installed or set-up correctly. There are two parts to satisfying this:
+
+1. Make sure you have an OpenCL driver installed that is compatible with your graphics card:
+ - GeForce (Nvidia): [http://www.nvidia.com/Download/index.aspx?lang=en-us]
+ - Radeon/FirePro (AMD): [http://support.amd.com/en-us/kb-articles/Pages/OpenCL2-Driver.aspx]
+ - Iris/HD (Intel): [https://software.intel.com/en-us/articles/opencl-drivers]
+
+2. Make sure you have pyopencl installed:
+ - Windows binaries are available at [http://www.lfd.uci.edu/~gohlke/pythonlibs/#pyopencl]
+ - Note: the link above distributes packages as 'wheels' (.whl).
+ - To install a wheel (this example being for a 32-bit Python 2.7 installation with no additional packages), cd to the download folder and then:
+{{{
+python -m pip install pyopencl-2015.1-cp27-none-win32.whl
