I'm 19 in chalsall's list. Like 47 in PrimeNet. Currently around 2.9K credit reported to GPU272.

Yes I'm Craig Meyers on the gpu-to-72 list, nucleon on the forums and the website http://www.mersenne.org.
As far as I know I have the fastest gpu farm on gimps. I think Xyzzy is number2. I'm responsible for about 3% ish of the entire GHz-days metric across the entire project at the moment. That's an interesting thought :) I'm not sure my percentage on the sub project. I cracked number 1 for the last 12 months yesterday. Woo :) My farm consists of: - 4x GTX580s - 2x GTX560TI - 1x GTX460 - 1x GT440 The 460 and 440 are doing LL DCs though. One of the GTX580 is running at 80% capacity. Only because I have run out of CPUs to supply them. :) You were would need more than 5x GTX580s to beat me. I only live in a single bedroom high rise unit. So power is probably an issue. I'm not to keen to buy more CPUs. I am keen to upgrade to Ivy Bridge E when it comes out. If it's released at 8cores, I'm there. My 15-day average is 1421GHz-days/day. I think peak is around 1467GHz-days/day. I'm lower than peak for the average as I had a large outage window with one of my nodes. Heat is a major issue. I'm keen to do a write up with more details and photos of my farm if anyone is interested. To keep in line with Xyzzy's stat - I'm 1GHz-day per 60.8secs. -- Craig |

I think 'interested' qualifies as an understatement. Yes please

They are much faster on CudaLucas, which unfortunately does not give the big credit given by mfaktc. To stay in line with your statements, I am the one who did 24 DC's for the project from the total of 47, so more then half, and I am on the same position as you if we talk about how many exponents we cleared. You have 1+32, I have 24+9 (DC plus factors). I think only kyle, pete and xyzzy beat us. Unfortunately, with mfaktc the speed compares to 580's, it seems that mfaktc is not able to get all the juice from the Teslas... To stay more in line: I could get 1GHz-day every 126.31 secs if I run them maxed, as maxed as the CPU's would let me do it, because that is a problem too. Unfortunately they never ran "mfaktc only", I would have no CPU power for it. I pour some CL from time to time and I have other things to do too (CAD software mostly need that power). The BIGGEST issue is also the heat, and that is more acute for the board in the middle, which is squeezed between the other board below and the CPU's fan above, and never gets enough flow of cool air. If I ever succeed to go to water-cooling, then we talk... :P Last fiddled with by LaurV on 2011-12-16 at 06:00 |

I'm sorry but that's not fair :) For the benefit of the project, I cleared a lot of 71-72 TFs. Which has similar chance of factors as 69-70, with 71-72 taking 4x the effort of 69-70. I also have 4x DCs done outside of the GPU-to-72 project. Give me a week, and I'll have another 3more done. If you're going to do that, I'll go grab the 69-70 range currently on the system and have it completed in under a week and see how many that generates. :) I'm sorry you can't use factors found as a strict comparison. Yes I'm aware of the issues with comparing LL GHz vs TF GHz. If you want to combine LL, TF, and P-1 work done into one metric that is fair, then I'd like to see a ranking. I'm thinking you need to find something like average number of TF GHz-days to find a factor (say x). And use that to reduce TF GHz-days down to a work-unit style metric, and reduce LL GHz-days down to a similar metric. -- Craig |

The ultimate goal of the project is to find primes, so therefore, the next-to-ultimate goal is to clear as many expos as possible in as short as possible time. Trial factoring that results into "no factors" does not give us too much gain (don't jump on my head, George said it, and that is the reason they do not really care about checking that "no factors" reports are not lies, see the discussion about adding a checksum (secret key) to mfaktc "no factor" lines, same as P95 is doing, nobody is interested in doing that, and they classified my complain as "overreacting").
So, what we do here? Exactly! We clear exponents. The rest is just talking, arguing, having fun, "my card is better that yours", "my cat can drink more milk" etc The rest, I agree with everything you said. It is impossible to compare different worktype on different platforms (CPU, GPU, etc). We are still arguing about that on a parallel thread on this very subforum. And the discussion is and it will be... endless. Last fiddled with by LaurV on 2011-12-16 at 10:13 |

I'd also be interested in knowing your KWh stats, and how you cool all of that!!! A/C, or vent outside? (Unless, of course, you also use it to heat your living space during the winter (assuming you live somewhere where it gets cold during the winter -- I don't enjoy that "luxury"... ))
