     7SAS model evaluations can run on your graphics card (GPU) or they can run

    76 SAS model evaluations can run on your graphics card (GPU) or they can run 
    77 on the processor (CPU). In general, calculations performed on the GPU will run faster. 
    78  
    79 To run on the GPU, your computer must have OpenCL drivers installed. 
    80 For information about OpenCL installation see this 
    81 :ref:`opencl-installation` guidance. 
    82  
    83 Where the model is evaluated is a little bit complicated. 
     81The logic for choosing the compute platform is a little bit complicated. 
    8482If the model has the line *single=False* then it requires double precision. 
    8583If the GPU is single precision only, then it will try running via OpenCL

    8987For models with a large number of parameters or with a lot of code, 
    90 the GPU may be too small to run the program effectively. 
    91 In this case, you should try simplifying the model, maybe breaking it 
    92 into several different modules so that you don't need *IF* statements in your code. 
    93 If it is still too big, you can set *opencl=False* in the model file and 
    94 the model will only run as a normal program on the CPU. 
    95 This will not usually be necessary.
