/*
According to the OpenCL v1.1 & v1.2 chapter 6.11.
Now define local and global size as following:
globals[0] = 4;
globals[1] = 9;
globals[2] = 16;
locals[0] = 2;
locals[1] = 3;
locals[2] = 4;
Kernel:
int id = get_local_id(0) + get_group_id(0)*2 + \
get_local_id(1) * 4 + get_group_id(1)*12 +\
get_local_id(2) *36 + get_group_id(2)*144;
