Error (vl_nnconv as a function) when using multiple GPU's #863

Open anestisp opened 7 years ago

anestisp commented 7 years ago

I am running Windows 8.1 (64bit) with Matlab 2016b and Cuda 8.0. Up to this point I had been using a GeForce GTX TITAN X and everything was working correctly. I just added a second GPU in my system (TITAN X (Pascal)) and I get the "Attempt to execute SCRIPT vl_nnconv as a function" error when trying to use both with cnn_train.

If I only use each card individually the code is executing as expected without any errors (although the Pascal card takes longer to start, which is a known issue accordin to Mathworks). The problem only appears if I attempt to use both GPUs at the same time.

Do you have any suggestions? I tried searching for similar issues online but I could not find anything relevant.

Regards, Anestis

For anyone else that might encounter this issue, Matlab 2017a seems to work properly.
