Question

The well know code for getting properties from CUDA devices (!) is enumerating over all devices, and getting properties from then. Then I see such piece, that activates given device.

I have problem in reverse — let’s say the device is already chosen, and I would like to get properties for it (the active one), not for all devices present in the system.

I hope I wrote this in correct way, because I am new to CUDA.

Answer 1

Just call cudaGetDevice() to get the device number of the active context, then call cudaGetDeviceProperties to get the properties of that device. In code that would be something like:

int device;
cudaGetDevice(&device);

struct cudaDeviceProp props;
cudaGetDeviceProperties(&props, device);
