cuda integer of 16 bits

Question

is there any 16 bits long variable in CUDA? I need an unsigned integer of 16 bits. I've tried:

uint16
uint16_t

But no one is recognized by nvcc.

uint16_t is a typedef in stdint.h. Add #include to your file. — Greg Smith, Nov 01 '12 at 01:24

May be you should try ordinary c unsigned short?

CUDA 8 (compute capability 6.x) comes with half-precision intrinsics. You can use the 16-bit floating point data type half or the integral types short2 / char4. These mixed precision types are packed into 32-bit device registers, which can double your performance over just using unsigned short.

some SO answers suggest that using composite types also speeds up code https://stackoverflow.com/questions/26676806/efficiency-of-cuda-vector-types-float2-float3-float4 – Alleo Sep 21 '18 at 22:35
