    : Convert Kernel.run() to OpenCL;
    note
       We also convert all 
       methods reachable from
       kernel.run()
    end note
    if (?) then (Conversion was successful)
       : Compile OpenCL;
       : Map compiled OpenCL to this Kernel;
    else (Conversion unsuccessful)
    endif
else (not first call)
endif
if (?) then (OpenCL mapped for this instance)
   : Bind args (send to GPU);
   : Execute kernel;
else (false)
   : Execute using a Java Thread Pool;
endif
