        <para>
          OpenCL allows applications to create a program object using the program source or
          binary and build appropriate program executables.  This can be very useful as it
          allows applications to load program source and then compile and link to generate a
          program executable online on its first instance for appropriate OpenCL devices in
          the system.  These executables can now be queried and cached by the application.
          Future instances of the application launching will no longer need to compile and
          link the program executables.  The cached executables can be read and loaded by the
          application, which can help significantly reduce the application initialization time.
