Struct CudaDeviceInner 

pub struct CudaDeviceInner { /* private fields */ }

Implementations

impl CudaDeviceInner

pub fn stream(&self) -> &Arc<CudaStream>

pub fn has_func(&self, module_name: &str, func_name: &str) -> bool

pub fn get_func( &self, module_name: &str, func_name: &str, ) -> Option<CudaFunction>

pub fn load_file( &self, path: &Path, module_name: &str, kernels: &[&str], ) -> Result<(), DriverError>

pub fn load_ptx( &self, ptx: Ptx, module_name: &str, kernels: &[&str], ) -> Result<(), DriverError>

pub unsafe fn alloc<T: DeviceRepr>( &self, len: usize, ) -> Result<CudaSlice<T>, DriverError>

Allocate an uninitialized device slice on this device stream.

Safety

The caller must initialize the returned allocation before any device or host read observes its contents.

pub fn alloc_zeros<T: DeviceRepr + ValidAsZeroBits>( &self, len: usize, ) -> Result<CudaSlice<T>, DriverError>

pub fn memset_zeros<T: DeviceRepr + ValidAsZeroBits, Dst: DevicePtrMut<T>>( &self, dst: &mut Dst, ) -> Result<(), DriverError>

pub fn htod_sync_copy_into<T: DeviceRepr, Dst: DevicePtrMut<T>, Src: HostSlice<T> + ?Sized>( &self, src: &Src, dst: &mut Dst, ) -> Result<(), DriverError>

pub fn dtoh_sync_copy_into<T: DeviceRepr, Src: DevicePtr<T>, Dst: HostSlice<T> + ?Sized>( &self, src: &Src, dst: &mut Dst, ) -> Result<(), DriverError>

pub fn htod_sync_copy<T: DeviceRepr, Src: HostSlice<T> + ?Sized>( &self, src: &Src, ) -> Result<CudaSlice<T>, DriverError>

pub fn dtoh_sync_copy<T: DeviceRepr, Src: DevicePtr<T>>( &self, src: &Src, ) -> Result<Vec<T>, DriverError>

pub fn dtod_copy<T, Src: DevicePtr<T>, Dst: DevicePtrMut<T>>( &self, src: &Src, dst: &mut Dst, ) -> Result<(), DriverError>

pub unsafe fn upgrade_device_ptr<T>( &self, cu_device_ptr: CUdeviceptr, len: usize, ) -> CudaSlice<T>

Wrap an existing CUDA device pointer in a typed cudarc slice.

Safety

cu_device_ptr must point to a live allocation containing at least len * size_of::<T>() bytes, and the resulting wrapper must not outlive the allocation or alias another owner that will free it independently.

pub fn attribute(&self, attrib: CUdevice_attribute) -> Result<i32, DriverError>

pub fn synchronize(&self) -> Result<(), DriverError>

pub fn ordinal(&self) -> usize
