Pageable host memory aysnchrounous copy to Device #92

Closed chenw11 closed 3 years ago

chenw11 commented 3 years ago

I want to set a copy action from pageable host memory to device memory into a Cuda Stream. But the CopyToDevice() does not have a overload method for Stream parameter? Although AsyncCopyToDevice() has parameter input support for cuda Stream, but it is intended for copy from device to device.

Look like we can only use PageLocked memory to do sync copy from host to device.

The (async) copy methods for pageable host memory are provided in the CudaPageLockedHostMemory class.
