Dear All,

Sometimes I got "Segmentation fault (core dump)" error message while training (with Cuda 7.0). If I reboot the machine everything works fine.

I don't know if this is caused by some unfreed GPU memory? Or garbagecollect does free GPU memory as well?

Is there a way to call cudaDeviceReset() via Torch7 / cutorch?

Any hints are highly appreciated!

Best regards,

Balint Toth

Hello,

There used to be a binding to this function but it has been removed due to unexpected behaviors. See https://github.com/torch/cutorch/issues/129 for details.

A call to collectgarbage does free unused memory on GPU.

Without more informations, it is hard to say what's the cause for this segfault. Maybe Soumith has seen this before?
