Driver version? #53

Closed NeuralDip closed 6 years ago

NeuralDip commented 6 years ago

Hi, i am using CudaContext.GetDeviceInfo() to get the driver info among other things, but for 'DriverVersion' i get a 9.0. Not a 22.21.13.8541 nor a 385.41. am i looking the wrong place?

CudaContext.GetDeviceInfo() calls cuDriverGetVersion() to get the driver version, which indeed returns the Cuda version number of the installed driver and not the driver version itself. As far as I know, there's no way to determine the exact driver version (e.g. 385.41) using the Cuda API. But if you really need that version number you can use NVML-library (also part of managedCuda but only in a very rudimentary way...) and use nvmlSystemGetDriverVersion().
