Cuda related helper functions.

Implementations

impl Cuda

pub fn device_count() -> i64

Returns the number of GPU that can be used.

pub fn is_available() -> bool

Returns true if cuda support is available.

pub fn cudnn_is_available() -> bool

Returns true if cudnn support is available.

pub fn user_enabled_cudnn() -> bool

Returns true if cudnn is enabled by the user.

This does not indicate whether cudnn is actually usable.

pub fn set_user_enabled_cudnn(b: bool)

Enable or disable cudnn.

pub fn cudnn_set_benchmark(b: bool)

Sets cudnn benchmark mode.

When set cudnn will try to optimize the generators durning the first network runs and then use the optimized architecture in the following runs. This can result in significant performance improvements.
