"3.12 million processor cores." !! don't know what to say.
But, can it play Crysis?
Don't forget that for super-computing they count individual stream processors in GPUs etc. 1160 Titans will get you up to 3.12m "cores" ... ;)Quote:

Well, they are leveraging GPU power (parallel processing) with the Phi's, that's exactly what they do. It's also been stated above, the core count includes all the GPU cores, the Phi has upto 61, so it's actually incredibly efficient.Quote:

WOW. Just WOW. SO MUCH POWER!!!!!!
So the Tianhe-2 must have a great cooling system as well? That sort of thing tends to be the limiting factor at the end of the day.Quote:

Sure it is defective. It is Made in China eh.
They added a big custom floating point unit to an old Pentium design. That's like strapping a rocket to a moped, you are welcome to ride that, I would rather walk :DQuote:

Even Nvidia got this right, they made cheap consumer cards like GT430 run FP64 instructions at a much reduced rate compared to the top end GPGPU cards, but the ability is there.
Oh course Phi failed as a graphics card, maybe the Intel CPU guys can see why and refuse to be tarnished by the project.
Haha, I like the analogy! I've read that the extenstions are only for the specific Xeon CPU and Phi combo. Someone described it to me as - "the Xeon mothership CPU and it's PCIe Phi drones"Quote:

Too powerful indeed! Supposedly Phi failed as a graphics engine because the architecture bottlenecked like crazy, guess it sucks for compute as well. Guess they tried to take their moped around a corner rather than just a straight line :D
Ahaha, that sounds ludicrous.
My main problem with simulations is if they can't saturate the GPU, the speed boost is neglegible over running it on the CPU - so it's a case of finding the sweetspot, it's never simple is it? I thought it would be the same for this, but assumed there'd be plenty of huge simulations to throw at it!
I'm still happy there's competition between the 3 companies in the GPGPU sector, good for the end users.
i reckon minecraft would blue-screen it haha jk
Got up yesterday checked the weather FINE
Played golf at 07.30 RAINED AT 10.00
All this TECH and they cant even get that mornings weather forecast right
