I’m getting:
Unhandled exception at 0x00007FF6FB22EFFB in MN2.exe: 0xC0000006: In page error writing location 0x0000000208300000 (status code 0xC0000022).
when iterating over 262144 (exactly the same every time) element of an array allocated with cudaMallocManaged (which returned 0)
I thought it may have something to do with heap/stack allocation limits in VC++ compiler but the problem didn’t get resolved after setting “Heap Reserve Size” and “Stack Reserve Size” to 10000000 both.
int main()
{
float *mat;
cudaMallocManaged(&mat, 1000 * 1000);
cudaDeviceSynchronize();
for (int i = 0; i < 1000 * 1000; i++)
{
mat[i] = 0.0f;
}
return 0;
}
I’m using VC++ and CUDA 10.1 on windows 10.
What is the reason of this error and how can I resolve it? Declaring arrays with more dimensions isn’t an acceptable solution here.
