Struct coaster::frameworks::cuda::Driver

pub struct Driver;

Defines the Cuda API.

Implementations

impl API

pub fn create_context(device: Device) -> Result<*mut Struct_CUctx_st, Error>

Creates a Cuda context.

An Cuda context can only be created with one device. Contexts are used by the Cuda runtime for managing objects such as command-queues, memory, program and kernel objects and for executing kernels on one or more devices specified in the context. An Cuda context is a synonym to a Coaster device.

pub fn destroy_context(context: *mut Struct_CUctx_st) -> Result<(), Error>

Removes a created Cuda context from the device.

Should be called when freeing a Cuda::Context to not trash up the Cuda device.

pub fn synchronize_context() -> Result<(), Error>

Synchronize the CUDA context associated with the current CPU thread.

Should be called when you want to make sure that previous asynchronous operations have been executed.

impl API

pub fn load_devices() -> Result<Vec<Device>, Error>

Returns fully initialized devices available through Cuda.

Combines the fetching of all device ids and the fetching of the individual device information.

pub fn load_device_list() -> Result<Vec<Device>, Error>

Returns a list of available devices for the provided platform.

pub fn load_device_info( device: &Device, info: CUdevice_attribute ) -> Result<DeviceInfo, Error>

Returns the requested DeviceInfo for the provided device.

impl API

pub fn mem_alloc(bytesize: size_t) -> Result<Memory, Error>

Allocates memory on the Cuda device.

Allocates bytesize bytes of linear memory on the device. The allocated memory is suitably aligned for any kind of variable. The memory is not cleared. Returns a memory id for the created buffer, which can now be writen to.

pub fn mem_free(memory: c_ulonglong) -> Result<(), Error>

Releases allocated memory from the Cuda device.

pub fn mem_cpy_h_to_d( host_mem: &FlatBox, device_mem: &mut Memory ) -> Result<(), Error>

Copies memory from the Host to the Cuda device.

pub fn mem_cpy_d_to_h( device_mem: &Memory, host_mem: &mut FlatBox ) -> Result<(), Error>

Copies memory from the Cuda device to the Host.

impl API

pub fn init() -> Result<(), Error>

Initialize the Cuda Driver API.

must be called before any other function from the driver API.

Trait Implementations

impl Clone for API

fn clone(&self) -> API

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for API

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
