Eigen::gpu::HostTransfer< Scalar_ > Class Template Reference

#include <contrib/Eigen/src/GPU/DeviceMatrix.h>

Detailed Description

template<typename Scalar_>
class Eigen::gpu::HostTransfer< Scalar_ >

Future for an asynchronous device-to-host matrix transfer.

Returned by gpu::DeviceMatrix::toHostAsync(). The transfer runs asynchronously on the given CUDA stream. Call get() to block until complete and retrieve the host matrix, or ready() to poll without blocking.

Member Function Documentation

get()

template<typename Scalar_>

PlainMatrix & Eigen::gpu::HostTransfer< Scalar_ >::get ( )

inline

Block until the transfer completes and return the host matrix. Idempotent: subsequent calls return the same matrix without re-syncing.

ready()

template<typename Scalar_>

bool Eigen::gpu::HostTransfer< Scalar_ >::ready ( ) const

inline

Non-blocking check: has the transfer completed?
