I'm a new user of linux. I installed the CUDA C driver. I run the executable file of the sample bandwidth test and it worked well. But when I tried to run the executable file of this code :
#include <stdio.h>
__global__ void helloFromGPU (void)
{
printf("Hello World from GPU!\n");
}
int main(void)
{
// hello from cpu
printf("Hello World from CPU!\n");
helloFromGPU <<<1, 10>>>();
cudaDeviceReset();
return 0;
}
I got :
$ ./code_1
Hello World from CPU!

and the device code doesn't show the expected result of repeating the string 10 times.
