Radeon 卡是否可以从 DisplayPort 读取数据（使用 OpenCL）？
Radeon 即将发布带有 DisplayPort 的显卡。我需要做的是不使用主机内存 (RAM)，而是直接读取从 Pegasus R6（直连 RAID 设备）传递到显卡的数据。也许使用 OpenCL 并在主机上利用 C/C++ 来控制流程。

Radeon is about to release videocards with DisplayPort. What I need to do is instead of using host memory (RAM) I want to read data passing from Pegasus R6 (direct-attach RAID device) straight to video card. Perhaps using OpenCL and utilizing C/C++ on host to control the flow.

已经有一些带有 DisplayPort 的基于 ATi 的卡，例如 PowerColor AX5770 (我用过）有一段时间了。但是你正在谈论将存储设备连接到显卡，据我所知这是不可行的。您提到的存储设备具有 Thunderbolt 接口，但虽然 Thunderbolt 确实支持 DisplayPort，但反之则不然。 Thunderbolt 是一种支持 DisplayPort 和 PCI Express 的混合接口，我当然会假设存储设备使用 PCIe 模式进行通信。因此，典型的显卡（仅支持 DP）无法承载存储设备（仅支持 PCIe），因为虽然物理和连接可能兼容，但协议却不兼容。
There have been ATi-based cards with DisplayPort such as the PowerColor AX5770 (which I use) for a while now. But you are talking about connecting a storage device to a video card, and this is not feasible as far as I can tell. The storage device you mentioned has a Thunderbolt interface, but while Thunderbolt does support DisplayPort, the converse is not true. Thunderbolt is a hybrid interface supporting DisplayPort and PCI Express, and I would certainly assume that storage devices communicate using the PCIe mode. So there's no way for a typical video card (which only supports DP) to host a storage device (which only supports PCIe), because while the physical and connection may be compatible, the protocols are not.
