I currently have cuda 4.0, OS is WIn 7, 64 bit.
I want to use UVA for transfers between CPU and GPU. Do I need linux for this? Or a fermi architecture card (TCC driver model) will do the miracle?
Do I need GPUdirect?
For cuda 4.0 I found the requirements:
[font=“Lucida Console”][i]Supported Platforms
Whether or not a device supports unified addressing may be queried by calling cuDeviceGetAttribute() with the device attribute CU_DEVICE_ATTRIBUTE_UNIFIED_ADDRESSING.
Unified addressing is automatically enabled in 64-bit processes on devices with compute capability greater than or equal to 2.0.
Unified addressing is not yet supported on Windows Vista or Windows 7 for devices that do not use the TCC driver model.[/i][/font]
Does anyone know what happens with toolkit 4.1?
the available cards are geforce gts 450 and gtx 460
