[PC World]1000-Core Processor Eats Quad-Core CPUs For Lunch - Page 8

I agree with those who mentioned this would rock with BOINC and folding@home. Imagine boincing 1000 work units simultaneously. Awesome. Science would seriously progress from a 1k cores processor in every home desktop.

They are, Bulldozer is being prepped.



Clock speed is still very important. If you have software that required 3.0GHz - then it required 3GHz. Most software can not handle or take advantage of multiple cores - so you still need raw CPU speed to do the job.



And Intel gets away with cramming GMA down people's throats. Of course, poor performance gets blamed on other things, like Windows or hard drives or memory - when really, the performance hit comes from poor graphics capability coupled with the robbing of valuable memory from the system.



I would call C2Q "powerful" - it's adequate for basic tasks, but lags like crazy if one wants to use stuff like Office.
I'll leave this here for you, since you obviously do not know the meaning of the word.

This is nothing special. I hate to sound condescending, but if the people at the University of Glasgow could make a processor to beat Intel's best, there'd be something seriously wrong at Intel. For a start, Intel spends something like $15 billion pa on R&D (an amount roughly 6 times larger than the size of the entire FPGA industry). Secondly, Intel has access to fabs and the like that Glasgow can only dream of.

What's really happened is that Glasgow has programmed an FPGA to have 1000 cores, which are then faster at certain types of operations than Intel chips. To the person who said 'can it run Crysis?' - that is exactly the sort of question that is (in this case) relevant. Intel chips are superior because they can do so much more than a relatively simple FPGA.

That's not to say FPGAs are useless - again, they can be programmed, and programmed correctly they can massively accelerate certain tasks (I remember reading a post from an x264 dev explaining how whilst CUDA offered few speedups in terms of rendering speed and quality, the improvements from using a dedicated FPGA add-in card could be vast - purely because they could tailor the specific types of calculations the FPGA card could make to those most often used in video encoding.

FPGAs are excellent for beating stuff like Amdahl's Law, because they can speed up the portions of your code that you can't make parallel.

It'd be slow with 1000 WUs, just have one going across all 1000 cores.

I'm not so sure about that. Just look at Windows Media Player and Media Player Classic: WMP developed by multibillion Microsoft, MPC developed by one guy (Gabest), and MPC was far superior.

Also, universities are often bleeding edge when it comes to science.

Why slow? If a processor has 1000 cores, it can handle 1000 work units simultaneously in BOINC.

This is designed for highly parallel workloads, each individual core is weak in most things, running one WU over all 1000 cores would be far faster.

That remains to be determined. It might not even have the processing power and functions to compute a WU in general, but even if it does, Amdahl's law would probably come into effect long before 1000 cores. In any case - just imagine how hard it would be to program for 1000 cores - short of splitting every WU into lots of smaller ones.

Software development is something that can be done by one person. If I am designing a media player, I can be using the same IDE as Microsoft (if I so choose) and compete - purely because I have no technological advantage. Chip design - much harder on a limited budget. Again, to make a chip from scratch to rival an Intel chip you'd need a massive fab and a hell of a lot of development time. Not cost effective. This is just reprogramming a chip that was designed to be reprogrammed - it's cool, sure, and difficult, but so are a lot of things. You can actually reprogram FPGAs in GUIs, drawing lines between logic blocks. Not saying it's easy - this processor was probably very hard to make - but it's certainly not on a par with Intel's latest efforts - especially considering the hard work was mostly done. It's nothing new - just noone has done it before.

Universities are bleeding edge, sure, but usually only at technologies, rather than products. For example, the University of Tyndall came up with a new type of transistor, which Intel has licensed from them. http://www.bit-tech.net/news/bits/20...with-tyndall/1

To add.... China has spent almost a decade on Loongson processors and it still can't compete. You don't just make up hardware. Chip fabrication is an art that can only learned through experience or acquiring knowledge/talent.
