Do you know if Intel Xeon Coprocessors work with BOINC? A 57 cores 1.1 GHz costs about 200€.

BOINC doesn’t know anything

BOINC doesn’t know anything about the Xeon Phi. It has code to check for CAL devices (ATI GPU’s from last decade), CUDA devices (Nvidia GPUs) and OpenCL devices which usually picks up the Intel iGPU’s and AMD GPU’s if the device driver is loaded. I’m not sure if the Phi has a suitable OpenCL device driver.

Even if it could be detected there aren’t any Phi apps, although in theory the OpenCL apps should work.

The server wouldn’t give out work for the Phi as it doesn’t know about it as a co-processor.

there are two varieties of xeon phi.

the card and the chip.

from what i've read, your money might be better spent

with either AMD or nVidia...

i think the phi was intel experimenting with scalability.

Pretty sure Intel abandoned

Pretty sure Intel abandoned Phi at this point. I remember seeing an announcement this year or last. It might be hard to find a motherboard that supports it as well. There was a sale when the product was still current. I asked Gigabyte whether the card is supported and it was a flat no and my MB was the top of their consumer lineup. You probably need a server board in order to get it working at first place, which is likely a few times more expensive than this card...

Also the picture you've shown is passively cooled, even though there was an active cooling variant. This means you likely need a server chassis as well. The normal air flow in a typical tower probably wouldn't be able to tunnel enough air through to cool it.

a particular Asus board, P9X79 Pro supported it. i have one. i still would waste money on it. from articles i have read the

card underperformed both nVidia and AMD at its debut.

The Co-Processor card

The Co-Processor card (Knights Corner) won't run BOINC for sure, it requires dedicated applications.
The CPU (bootable) version of Knights Landing should be able to run any x86 applications, but I believe its performance will be poor. It's based on older Atom cores with added AVX512 support. So if anyone is looking for a good multi-core machine, a Threadripper is a much better choice.
