I can not figure out the cause of the error when solving the cuda example.

first i use ubuntu 16.04

global void add(int a, int b, int *c){
*c=a+b;

}

int main(){

int c;
int *dev_c;
HANDLE_ERROR(cudaMalloc( (void**)&dev_c, sizeof(int) ) );
add<<<1,1>>>(2,7, dev_c);
HANDLE_ERROR( cudaMemcpy( &c, dev_c, sizeof(int),cudaMemcpyDeviceToHost));

printf("2+7 = %d",c);
cudaFree(dev_c);
return 0;

}

and i have trouble like this

won@won-desktop:~/cuda_example$ nvcc ex1.cu
won@won-desktop:~/cuda_example$ ./a.out
CUDA driver version is insufficient for CUDA runtime version in ex1.cu at line 14
won@won-desktop:~/cuda_example$

i dont know why is it not run…could u help me ?

solved i chnage nvidia-smi to 396.26 then work!!

390.xx did not contain CUDA 9.2 runtime so it can’t run 9.2 compiled apps

use old SDK or, as you did, upgrade to 9.2 capable driver version
