    Interface ITensorData

    Interface for device dependent representation of Tensor data.

    Namespace: Barracuda
    Syntax
    public interface ITensorData : IDisposable

    Methods

    Download(Int32)

    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. count is the number of elements to readback. count can be less or equal to the number of elements in a specific tensor.

    Declaration
    float[] Download(int count)
    Parameters
    Type Name Description
    Int32 count
    Returns
    Type Description
    Single[]

    GetMaxCount()

    Return the maximum number of element this tensorData can contain.

    Declaration
    int GetMaxCount()
    Returns
    Type Description
    Int32

    Reserve(Int32)

    Reserve uninitialized memory.

    Declaration
    void Reserve(int count)
    Parameters
    Type Name Description
    Int32 count

    ScheduleAsyncDownload(Int32)

    Schedule an asynchronous download from device memory. count is the number of element to readback. returns false until data from device arrives to CPU and is ready for access.

    Declaration
    bool ScheduleAsyncDownload(int count)
    Parameters
    Type Name Description
    Int32 count
    Returns
    Type Description
    Boolean

    SharedAccess(out Int32)

    Returns an array filled with the values of multiple tenors that share the same tensorData on device. This function outputs offset from the beginning of the array to location of values for specific tensor. offset paramater is specified in float elements. Depending on the implementation and underlying device this array might be a copy or direct reference to tensor values. This is a blocking call, unless data from device was requested via ScheduleAsyncDownload beforehand and has already arrived.

    Declaration
    float[] SharedAccess(out int offset)
    Parameters
    Type Name Description
    Int32 offset
    Returns
    Type Description
    Single[]

    Upload(Single[], Int32, Int32)

    Initialize with data. offset is the offset where to start the copy in the data count is the number of element to copy. If count is -1 (default) number of element will be (data.length - offset).

    Declaration
    void Upload(float[] data, int offset = 0, int count = -1)
    Parameters
    Type Name Description
    Single[] data
    Int32 offset
    Int32 count
