    Method
    Description
    static com.jogamp.opencl.CLContext
    createContext()
    Creates OpenCL Context using most powerful available device The decision of the device relies on inner calculations of JogAmp's implementation, which can mistake number of processing units on cards RTX 4xxx as of version 2.5.0
    static boolean
    isOpenCLAvailable()
    Checks if any present device supports OpenCL or returns false straight away, if initialization is impossible Also enforces minimal supported work group size to 256 as this value needs to be present as constant in .c source files
    static void
    release(com.jogamp.opencl.CLContext clContext)
    Should be called before the OpenCL context is erased.
    static CLProgram
    useProgram(com.jogamp.opencl.CLContext clContext, CLProgramDef programDef)
    Compiles the OpenCL program, re-uses already compiled programs.
