If i just run or debug with local windows debugger, everything works fine.
Just 2 weeks ago, i debug with CUDA Debugging(Next-Gen) also works fine.
But today, I try to debug with CUDA Debugging(Next-Gen) just as the weeks before, terrible and strange things happen!
Process:
1、Write a very simple cuda program. Set debug mode with -g -G.
#include <stdio.h>
__global__ void fillArray(int* arr, int size) {
int idx = threadIdx.x + blockIdx.x * blockDim.x;
if (idx < size) {
arr[idx] = idx;
}
}
int main() {
const int size = 10;
int hostArr[size];
int* devArr;
cudaMalloc((void**)&devArr, size * sizeof(int));
fillArray << <1, size >> > (devArr, size);
cudaMemcpy(hostArr, devArr, size * sizeof(int), cudaMemcpyDeviceToHost);
for (int i = 0; i < size; i++) {
printf("hostArr[%d] = %d\n", i, hostArr[i]);
}
cudaFree(devArr);
return 0;
}
2、Build
3、Add some breakpoints
4、Extensions->Nsight->Start CUDA Debugging(Next-Gen)
5、Successfully get into break point in the first line of main function
6、I find that when debugging, i can’t put the breakpoint in global function, and it prompts me that the breakpoint does not exist.
6、Everytime stepping next to cuda function(sometimes cudamalloc, sometimes cudamemcpy), the computer get stuck with no response, sometimes the whole screen gets black, and i have to force to restart my computer.
7、Sometimes the computer will recover after a crash (I still can’t enter the breakpoint, and it prompts me that the breakpoint does not exist), and I saw the following error message.
What is the problem?
I could give any information, can anyone help me?
