Hi
Newbie question...
Would something like this Xeon Phi PCI co-processor card "just work" with BOINC?
http://www.ebay.com.au/itm/Intel-Xeon-Phi-31S1P-Coprocessor-8-GB-57-Cores-1TFLOP-270W-Sealed-BC31S1P-New-/222098831440?hash=item33b61f3850:g:fVwAAOSwpDdVTyRr

i.e. plug it in and you get 57 cores crunching away?
Or is a high end video card better?

Thanks
Dave.

Xeon Phi is more kin to a GPU than a CPU. The first benchmark I found suggests its performance is not that hot http://blog.xcelerit.com/intel-xeon-phi-vs-nvidia-tesla-gpu/.
Further it would probably need a custom build of the applications to run properly, and as far as I'm aware nobody has trodden that path with v8.

I think someone on here had a Phi when they first launched but I'm not sure if they ever managed to do anything with it.

That Xeon Phi looks to have similar performance specs to my R9 390X. Plus we already have apps for GPUs.

You need to talk with Ivan as he was playing with them. ;-)

Cheers.

Would be nice if we could use those since they going for dirt cheap on ebay

I came down with a bad case of i don't give a crap

It looks as if Ivan gave up with trying some time ago.
This appears to be his last message on the subject:

Problems like those expressed by Ivan may well explain why they are going cheap on flee-bay

As I wrote in that thread - a way to try could be to check if OpenCL runtime available for such device and if yes, to rebuild current OpenCL SETI sources with this device as a target.
Perhaps some porting efforts could be required but at least in such approach parallelization work mostly done by runtime and already existing code. Should be much easier than write new heavely parallel app with native API whatever it is.

i wish i would know more about these cards you can buy 10 of those for about 600$
thats quiet a bit of computing power

If they are going for $60 a piece. Then donating one for development probably wouldn't would to awful.
