Methods

Dispose()

Declaration

public virtual void Dispose()

Download(TensorShape)

Returns an array filled with the values of a tensor. Depending on the implementation and underlying device this array might be a copy or direct reference to the tensor values. This is a blocking call, unless data from device was requested via ScheduleAsyncDownload beforehand and has already arrived.

Declaration

public virtual float[] Download(TensorShape shape)

Parameters

Type	Name	Description
TensorShape	shape	the TensorShape (and thus length) of the data to copy

Returns

Type	Description
float[]	Tensor data as float arrary

~TextureTensorData()

Declaration

protected ~TextureTensorData()

Reserve(int)

Reserve uninitialized memory.

Declaration

public virtual void Reserve(int count)

Parameters

Type	Name	Description
int	count	element count to reserve

ScheduleAsyncDownload(int)

Schedule an asynchronous download from device memory. count is the number of element to readback.

Declaration

public virtual bool ScheduleAsyncDownload(int count)

Parameters

Type	Name	Description
int	count	count of elements to download

Returns

Type	Description
bool	false until data from device arrives to CPU and is ready for access

SharedAccess(out int)

Returns an array filled with the values of multiple tensors that share the same tensorData on device. Depending on the implementation and underlying device this array might be a copy or direct reference to tensor values, no conversion from on device memory layout will occur. This is a blocking call, unless data from device was requested via ScheduleAsyncDownload beforehand and has already arrived.

Declaration

public virtual BarracudaArray SharedAccess(out int offset)

Parameters

Type	Name	Description
int	offset	This function outputs offset from the beginning of the array to location of values for specific tensor. offset parameters is specified in float elements

Returns

Type	Description
BarracudaArray	array filled with the values of multiple tensors that share the same tensorData on device

ToString()

Declaration

public override string ToString()

Returns

Type	Description
string

Overrides

object.ToString()

Upload(float[], TensorShape, int)

Initialize with data. shape is the TensorShape (and thus length) of the data to copy. managedBufferStartIndex is the offset where to start the copy in the data

Declaration

public virtual void Upload(float[] data, TensorShape shape, int managedBufferStartIndex = 0)

Parameters

Type	Name	Description
float[]	data	data as float array
TensorShape	shape	Tensor shape
int	managedBufferStartIndex	managed buffer start index
