You sure sound very confused Jack007
---------------------------------------- Calculating your own GFlops contribution is easier than you might think. Here's how: 100 BOINC points per day equal 1 GFlops (1 GFlop/second) by definition. So take your average BOINC points per day for WCG (RAC) and devide that by 100 and you have your GFlops contribution. I have about 780 Boinc points per day, so that's 7,8 GFlops. That's it !! If you take your average WCG points per day devide by 700 to get GFLops. |

Ok thanks for responses.
----------------------------------------I've still only had like 3 hours sleep but lets see if I got this. Roughly 35000 WCG points/day is 5000 BOINC points. 5000 Boinc points is 50 GFLOPS. (should be Belly flops for Billions) so 400 Tflops is 400,000 GFlops, which means my computers are 1/8000 of daily production. (or in case of I7 that I used in above example about 30 GFlops 1/12727 of WCG power) suspiciously close to my 13000 I estimated earlier. So if my numbers worked out that neatly, I get nervous. I'll reread and see if I can get anything else out of your previous responses. Edit: Ok, after rereading Sekerob's post for the 3rd time it's starting to sink in. If a Q6600 is/would be 1/22000 of total, then 1/13000 is about right for I7. (I have one of each plus a laptop). Ok, it's becoming less fuzzy, thank you so much for your clearing it up for me. (I'ma right down the quick and easy divide by 700 to get GFlops formula, I have serious sleep issues, therefore, memory issues) On a bright note, got back a 1.8 ghz (think/hope it's a dual core). Gonna get that sucker up for a couple days of runtime, for grand total of 15 cores.   [Edit 1 times, last edit by Jack007 at May 7, 2010 7:10:04 PM] |

Ahhh! At last it is clear for me. I had given up calculating these ratios months ago because I was going nowere. In fact I was starting from the rated i7 CPU performance published by Intel through their proprietary benchmarks which made everything very confusing.
----------------------------------------Now I can finally relate credits points and TFlops.!!!! So 100 Boinc Credits are 1 GFlop. Or 700 WCG points are 1 GFlop. Result for yesterday: 525'759 ------> 751 GFlops. My all time daily max was: 587'452 -------> 839 GFlops Wow! I am not so far from the Teraflop. Dunno if I can reach that in the future but not bad at all. It means I contribute in average 1/500 of the total crunching power. Excellent!   |

WOW Hypernova that is AWESOME!
----------------------------------------And 'knowing' you, you won't be able to stand it. You'll have that Terra flop, at least a record day by the fall (earlier if heat doesn't become an issue I bet!) I can't remember if you OC, but if you don't, I bet you could hit it in a couple days  Another way to look at it, if I do 50 GFlops then I do 3 terraFlop (s) in a min. so 3*60= 180 terraFlop(s) (plural not per second) in an hour, or 4.3 PetaFlop(s) per day. (and yes I use misspelled terra on purpose since you & I are running bodies of the solar system). |

I can't remember if you OC, but if you don't, I bet you could hit it in a couple days Jack all my machines are already overclocked a lot but not to an insane level. Don't want to fry my nice little 980X chips. I am running out of available electrical power and space. Heat is also a problem if external temps raise to high. So it will be a challenge to reach the 1TFlop. I expect to reach this as a peak performance but not as a base daily level. You are right I love challenges but this one will be a very hard one. Anway I'm already working on it.  |

Movieman, I could not believe my score yesterday.
----------------------------------------0.986 TFlop.  Nearly did it.  This score is fully crunching on HCMD2. Back to work. [Edit 1 times, last edit by Hypernova at May 13, 2010 6:34:28 PM] |

Movieman, I could not believe my score yesterday. 0.986 TFlop. Nearly did it. Back to work. Like I said,you'll get there and soon.. Small technical issue that the hardware people might be interested in: One of the problems in getting high speed ( above 4000-4200MHz) from the new 6core Intel cpu's has been the locked uncore at 20x. Say you've got a X5650 Westmere with it's 20 multi and you want 4000mhz you need to push the BCLK to 200 (20x200) BUT for 200BCLK you need 1.4VTT and 1.4VTT ( IMHO) is a way to slow death on the cpu if used for 100% load 24/7 work as we do. Now heres where it gets interesting. Gigabyte has just released a new bios for their X58 UD7 boards with the new microcode patch from Intel and now that uncore is unlocked. That means you can push upwards of 220BCLK with just 1.3VTT( very safe voltage) I know this isn't directly related to the 400TF machine but it is. I can see 60,000PPD coming from a single socket 6 core running at 4400-4500MHz.. [Edit 1 times, last edit by Movieman at May 13, 2010 6:36:01 PM] |

I can see 60,000PPD coming from a single socket 6 core running at 4400-4500MHz.. With air cooled CPU? And at 4'500 Mhz what kind of power consumption will we have? 300-350 Watts at wall socket. Global power consumption at those clocks will increase exponentially. What d'u think?  |

Global power consumption at those clocks will increase exponentially. What d'u think? No, for above app 4200mhz you do need water cooling. Yes, power levels do increase but I can rationalize it this way: It's one system producing that output and the energy needed to make all the parts for the second system wasn't needed.. My SR2 rig draws app 620w at 4200MHz( on air) making over 100,000PPD With a i7-920 based machine you'd need three of them to match that and I'd guess the three would draw more than 620W total. Anyway, thats my logic and I'm sticking to it! |
