this test case shows how to execute CM kernel via OpenCL APIs.
the CM kernel source code is already compiled into file "cmrt_utest_genx.isa" with offline compiler.

I also copied the CM kernel source code and CM host source code here for your reference.

CM kernel source code:
#include <cm/cm.h>
extern "C" _GENX_MAIN_  void
simplemov(SurfaceIndex ibuf, SurfaceIndex obuf, uint d)
{
    matrix<uchar, 1, 4> in;
    matrix<uchar, 1, 4> out;

	uint h_pos = get_thread_origin_x();
	uint v_pos = get_thread_origin_y();

	read(ibuf, h_pos*4, v_pos, in);

	out = in / d;
	write(obuf, h_pos*4, v_pos, out);
}

CM host source code:
