CUDAMemoryCopyToHost

CUDAMemoryCopyToHost[mem]

force copies CUDAMemory from the GPU to the CPU.

Details and Options

Examples

Basic Examples  (1)

First, load the CUDALink application:

Wolfram Language code: Needs["CUDALink`"]

This loads a Range[10] list into CUDALink:

Wolfram Language code: mem = CUDAMemoryLoad[Range[10]]

This gives information about the returned memory. Notice how the "DeviceStatus" is "Uninitialized":

Wolfram Language code: CUDAMemoryInformation[mem]

This forces a copy from the host memory (CPU) to the device memory (GPU):

Wolfram Language code: CUDAMemoryCopyToDevice[mem]

This gives information about the returned memory. Notice how both "HostStatus" and "DeviceStatus" are "Synchronized":

Wolfram Language code: CUDAMemoryInformation[mem]

This will perform an unnecessary copy from the device to the host:

Wolfram Language code: CUDAMemoryCopyToHost[mem]

The information is not changed:

Wolfram Language code: CUDAMemoryInformation[mem]
