125 dolara 10 komada deluje pristupacno 58 jezgara, spominje se c++ ali pise da su koprocesori zanimljivo nema sta samo ti sto znaju da ovo radi nemaju vremena ni zelju da pisu o tome mlate lovu trenutno...ja 1kom ako radi
*For the cost, you'd be better off just buying an Nvidia card like the 970, especially after this promo ends. You could buy a bunch of 970s for $1700. Also, it would take serious modding to the engine itself. Waaaayyyyy more trouble than it's worth.
*Not exactly. The attraction of the Xeon Phi is that it's x86 based and is (oversimplifying) a cluster of processors on a single die. Software needs to be recompiled to take advantage of the Phi, but not necessarily designed specifically for it. I've run large-scale MPI codes on the Phi unmodified, apart from recompiling them with the appropriate flags in the Intel compiler. The programming model is basically the same as how you code for distributed memory clusters/supercomputers. Software could also potentially get a boost with no changes at all if it dynamically links against Intel's MKL, which will use a Phi automatically to accelerate numerical calculations if one is available.
This is a ridiculously good deal (I'm drooling here over how much time 10 of these could save me at work, we're talking literally months or years), but you shouldn't be buying one unless you already know how to use it. It's an enormous waste for pretty much anything a home user would ever want to do, even an advanced one. And it'd probably melt under load without high-displacement fans pulling air though it, these things run pretty hot in my experience.
Edit: Well, I guess they might be good for Bitcoin mining, I suppose that might be a legit "home" use case.
*Folks, despite the issue raised with fans, etc, the largest issue with the Xeon Phi Copro cards is that your motherboards will not work with it.
The cards require an 8GB aperture for memory mapped I/O. Unless you purchased your motherboard for the Xeon Phi, it's likely not compatible.

This is not something that a buncha fans ziptied to the card can solve, it just means you won't be able to use the tiny supercomputer.
