OpenCLMemoryCopyToHost
OpenCLMemoryCopyToHost[mem]
force copies OpenCLMemory from the GPU to the CPU.
Details and Options
- The OpenCLLink application must be loaded using Needs["OpenCLLink`"].
- OpenCLMemory is returned by OpenCLMemoryLoad or OpenCLMemoryAllocate.
Examples
Basic Examples (1)
First, load the OpenCLLink application:
Needs["OpenCLLink`"]This loads the Range[10] list into OpenCLLink:
mem = OpenCLMemoryLoad[Range[10]]This gives information about the returned memory. Notice how the "DeviceStatus" is "Uninitialized":
OpenCLMemoryInformation[mem]This forces a copy from the host memory (CPU) to the device memory (GPU):
OpenCLMemoryCopyToDevice[mem]This gives information about the returned memory. Notice how both "HostStatus" and "DeviceStatus" are "Synchronized":
OpenCLMemoryInformation[mem]This will perform an unnecessary copy from the device to the host:
OpenCLMemoryCopyToHost[mem]The information is not changed:
