Restrictions

For SIMT programming, this API is not supported.

Header Files to Be Included

To use this API, the simt_api/vector_functions.h header file must be included.

#include "simt_api/vector_functions.h"

Examples

For SIMD and SIMT programming:

__simt_vf__ __launch_bounds__(1024) inline void kernel_make_uchar4(__gm__ uchar4* dst, __gm__ unsigned char* x, __gm__ unsigned char* y, __gm__ unsigned char* z, __gm__ unsigned char* w)
{
    int idx = threadIdx.x + blockIdx.x * blockDim.x;
    dst[idx] = make_uchar4(x[idx], y[idx], z[idx], w[idx]);
}
