Hi, My idea is to use external graphic card for connecting monitor ang IGP HD 4000 (on CI7-3770) or HD3000 (on CI7-2600) for parallel computing support using OpenCL. Is it possible? What system configuration I should use?
I think it's not possible as the GPU cannot not be accessed in headless mode. I have a i7-3770K with a GTX680. When I'm using GT2, I make iGPU my primary GPU (boot from IGPU).

It's a pity:(
Hi Mikhail,
We are aware of this limitation and looking into this. Unfortunately I dont have any more details at this point.

Hi Raghu, looking forward hearing news from you.
I found out more about the issue. Theoritically this is supposed to work _if_ you are in a hybrid mode - meaning you have Intel's Processor graphics and have a discrete card - with both the drivers installed and using the discrete as your primary adapter. Currently this is not working and we are working on a fix in the driver.
Now, if you have switchable graphics then the proxy driver comes from the discrete graphics card vendor and that's a different story.
Can you let me know what your configuration is and whether your system has switchable graphics?
Thanks,
Raghu
I have Ci-7 3770 with external nVidia card. Display is connected to nVidia. My idea was to use IGP for calculation of my algorythm. I have Linux and Win7. I'm not sure i have IGP drivers installed, i'll check. Ans this is desktop, so no switchable graphics, i think...
