Hi, it would not make sense to develop a new GPU-Aplication to finish the Project in 100 instead of xx days. I expect a lot of new HCC-Work for us to crunch. I would also guess that WCG is looking at other projects to bring into the gpu arena too. Time frame obviously unknown at this point in time. Maybe Lawrence can shed some light on that, but it is likely those kinds of things are being held close to the vest. There ARE of course some things still be tweaked in the current gpu process so I personally am not looking for another project in the near future. But once that path is started it is hard to get off, after all more work in less time is usually a VERY good thing!   [Edit 1 times, last edit by mikey159b at Oct 21, 2012 12:49:10 PM] |

For very much people on the world the save of 1,5-2 Years is more then they has lifetime left..so im sure it make sense for them or better (because the laboratory work that must be done after calculations) the future generation who get ill in the next years..

If you could convince those bitcoin miners, they could complete this project in one day. There are a lot of them out there that own 100+ HD 7970s, that is how they make their living. Looking at the estimate in February. The Bitcoin network made up of entirely AMD graphics cards (everyone makes sure to buy several of the latest cards every 2 years with the bitcoins earned), with a total of 208,000 TFLOPS of power, in comparison, Folding@Home only averages 8,600 TFLOPS. WCG is tiny compared to that. I think when the new bitforce FPGAs come out they will ditch their graphics cards (sell them on ebay or use them on BOINC).
----------------------------------------Fun fact: Fastest supercomputer in the world is only 20,000 TFLOPS. On another note: graphics cards are slow, I'd like to see some FPGA action here in the near future. They are typically several hundred/thousand times faster than a graphics card at the same power level. [Edit 3 times, last edit by mmstick at Oct 21, 2012 5:08:18 PM] |

Providing that ALL have 7970 cards, realistically how many % of all the GPU crunching at this moment and 1 year ahead do you think have or will have 7970 cards? Well, this was a rough estimate by me of how few cards HCC would need to handle newly-crystallized results themselves, after the WCG-part is finished, so can expect all cards would be equal. Now, if this would be very expensive Tesla-cards to also handle other things besides HCC or instead cheap Amd-HD7950-cards is another matter. As for 22 seconds per task as mmstick hinted at, if HCC does the crunching themselves it's unlikely they'll overclock their systems and running more than one task per GPU is also doubtful. The possible speedup from 89xx-cards on the other hand can be significant, so let's say HCC uses 1 minute per image and would need 70 GPU's to handle 100k crystallizations per day. By using WCG to do the work instead and if assumes all GPU's only uses 22 seconds per task, to handle 100k images per day there's only work for 51 GPU's.  "I make so many mistakes. But then just think of all the mistakes I don't make, although I might." |

my 7870 isn't much slower than the 7970. also at least 100.00 cheaper

my 7870 isn't much slower than the 7970. also at least 100.00 cheaper HD 7870 = 256-bit memory interface & 1280 HD7xxx shaders @ $230 HD 7950 = 384-bit memory interface & 1792 HD7xxx shaders $ 310 HD 7950 has +40% the total computational cores and + 50% faster memory interface for +35% the extra cost. Sounds like a much better deal to me. All HD 7950s are guaranteed to clock to at least 1100Mhz core and 1400Mhz memory with little to no voltage increase, which makes them as fast, or a little bit faster than a 7970 running at stock frequencies. At one point HD 7970s did reach around $350 mark, but it seems they have gone back up again. The difference between 7970 and 7950 is +15% additional computational units. Rumour is HD 8970 will have ~2300 cores compared to the 2048 in HD 7970, with likely higher frequencies and hopefully some nice architectural improvements for making OpenCL faster.

I'm not to geeky so i only run 1 wu at a time some finish in 1.28 min and some 1.34 min elapsed time.
----------------------------------------points per day not sure but my credit per day according to boinc stats has gone from 5k to 32k per day stock out of the box no oc done to it. also when idle goes to 37c while crunching it peaks at 44c. so it goes off and on as needed between wu's. use's only 83% of compute power [Edit 2 times, last edit by Former Member at Oct 23, 2012 11:57:24 AM] |
