-To generate random numbers on the host CPU, the memory allocation in step one should be made using a host memory allocation call. In step two ``rocrand_create_generator_host`` should be called respectfully. In the last step, the appropriate memory release should be made using the ``rocrand_destroy_generator``. All other calls work identically whether you are generating random numbers on the device or on the host CPU.

 In the example below, the C host API is used to generate 10 random floats using GPU capabilities.
