And still moving upward. I think I will top out somewhere in the 675k ballpark without adding any more machines. But I do have another Intel 2500k CPU and motherboard on the shelf and that could easily push me into the 725k Range. I guess the real goal would be 1 Million per day. I would need two more 30amp circuits installed in my office to get to that level. Todd |

Methinks you'd need a dedicated line straight to the SSL too, moving that many WU's a day. By some simple math and gross estimations, you'd have to average ~350k/bits to keep the machines loaded at a 1mil RAC (10,000 WU's a day @ 100pts each, 375k/bytes). Even now I'd say you give your network quite the workout for a small business :) |

The network bandwidth hardly is noticeable - running a 65m/7.5mb connection. What has become ever noticeable is heat - the new rig really blasts out the BTU's! Of course the HAF-X case expells it out nicely so internally it isn't bad at all. Todd |

This is definitely a "live vicariously" situation. I know I'm envious. Get that 1 million/day, I think we'll all be proud. |

I guess the real goal would be 1 Million per day Just a question of having enough systems. Now what would be really impressive is a single system that has an RAC of 100,000. EDIT- Say a multi-CPU Sandy Bridge EP Octo core system with a few GTX 580s? Grant Darwin NT |

EDIT- Say a multi-CPU Sandy Bridge EP Octo core system with a few GTX 580s? A dual six core motherboard with 4 580's crunching around the clock would result in a rather large number for sure. Would hate to see the cost of that machine if/when it becomes reality, not to mention the power bill! Todd has one machine with 4 x 570's that's got 1192 tasks completed on the video cards(~131,120cr.) I imagine a 580 would complete a bit more than that but it's hard to guess how many more. Steve has 1 6 core 980x machine, today he completed 110 WUs(~11,990cr.). So if you had two of those and 4x 470's you should be able to hit about 155,320cr. per day. Of course these are extremely rough estimate as I'm not sure how long they dedicated today to crunching or any downtime they may have had ect. So I guess it could be argued the top machines out there are running on tip top performance and most of the time. The top single machine as of right now is running an i7-920 w/ 3x GTX 295's. His RAC is only 100,873.61. So you could argue with 8 more cores and another card in there you would have a higher RAC, but it wouldn't be 10x higher for sure! That's a ton of credits! None the less we are traveling more and more that way by the day in computing! In '99 the amount of work we are pushing now would have been unbelievable. Traveling through space at ~67,000mph! |

The new Sandy Bridge machine and the lot of my machines at home were all forced offline last evening because my cable modem went down and needed to be reset. Right now my 8 machines here are fighting to upload all of their tasks - more than 10k that need to find their way home. This should make my RAC bounce to the low 630's. I do agreee that having one system that can produce 100k is very impressive and is a goal that I do share. I'm considering moving around some of my GTX-295's into a single system and doing some consolidation. With the majority of my machines running dual hex-core cpu's I do get a benefit of the processing power of my CPU's - however the GPU is much more powerful. But still waiting for the fermi optimized code to become available and thus far this hasn't happened. But with my 570's I am seeing compute times as fast as my 295's ever could. The 580's just don't seem to be worth the extra $150 per card premium that they are calling for right now and the 570's seem to be highly overclockable. The stock gpu clock is 732mhz and without making any changes to voltages I have mine at 795mhz. So a pretty good performance jump. With two tasks ran on each card and 80% gpu usage they are coming in at 12m30s on average. There is still more room for better performance. I wanted to get a better idea on the new platform what to expect before jumping to the next level with an EVGA SR-2 and dual hex-core cpu's. The board is expensive but I already have the cpu's but might be better served just getting a different single socket board that supports 4 cards - EVGA 4 way classified is what direction I'm heading. The additional cpu would add about 13k-15k of performance and that comes with a significant price tag. Considering that a current system with 3 480's and a hex-core cpu running at 3.6ghz does 73k RAC - a 4x-570 system with the 2600k @ 4.5 Ghz should easily come in at 95k if not more. Todd |

Sheesh..... I can remember when one of my goals was to reach 100K RAC with all of my rigs combined. My Frozen 920 with 2 GTX295s is just under 73K RAC....and that's only good enough for the #11 spot in top computers at this time. How things have advanced, eh?

Correction, the 570's are doing two WU's in 13m30s on average and advancing 7k RAC per day. It has only been online for 5 days total and has reached a 32.5k RAC - and there were some problem days in there without the ability to upload and also the weekly outage so I'm sure that some of my wingmen might not have been able to get their tasks in as of yet. For me having a 10 day cache is almost mandatory on these higher performing systems until I get the DCF leveled off to normal rates. Todd |

Things over the years have changed a great deal. It is easy to see the effects of Moore's Law just on this project alone. And that Law doesn't take into consideration the impact of GPU computing. Todd |

I just ordered a dual x5680 with 4 gtx580 cards from digital storm, all water cooled and overcloked, just for processing units for Seti. Can't wait to see what kind of numbers this rig can produce. For those interested the cost of this setup is a little over 14 grand. I'll be looking for some advice on how to tweek things for Seti. I have had Seti for a number of years, but just recently finding out about optimized programs like Lunatics, and have no idea where to change the settings to let each gpu process multiple units like I have read about here. So maybe I can get some help from someone with patience for the inexperienced to help out. I have an alienware area 51 with the 980x and 2 gtx 580s now, but so far ot appears one of my olders systems with 2 gtx280s is outperforming it. ( I just installed the gtx580s, replacing the 2 hd5970s that came in the system) I have a long way to go catch Todd:-), but don't mind trying. |

It's easy to set your count to run multiple WUs at a time. Shut down SETI and BOINC, go into your app_info file and find each instance where it says <count>1</count> and change it to .5 for two at a time, .33 for three or .25 for four at a time. In a 64 bit system I believe there are six you have to change. Be sure to open the app_info file with notepad so that nothing else gets added to your changes. Save, exit and start BOINC manager. That should do it. PROUD MEMBER OF Team Starfire World BOINC |

What would put Todd waaaay over the top is if somehow the folks at lunatics managed to get the AVX instruction set working on his new core i7 systems. I don't know if y'all have seen the benchmarks for computing with the avx instructions enabled, but they're extremely extremely extremely fast. When used for encoding video, it's faster than a 980x WITH a GTX 580. I don't even know if it's possible to use AVX with seti, but if so, I suspect that we will see a ton of people upgrading (or at the very least, those of us who enjoy the competition side of it). I know I'll be jumping on that bandwagon if that comes to pass. It's really amazing just how far we've come over the past few years. I ran seti for many years back in around the turn of the century (sounds so funny to say that now) and I racked up about a million credits. I stopped for several years because I got into animation and video editing, so my CPU time was always being used for something or other. I began crunching again late last year and I've already surpassed the TOTAL amount of work units that I did in several years by a factor of two. I still feel giddy when I open up the windoze task manager, or look at my CPU usage monitor on my desktop and I see the 8-cores on my laptop (4 with hyperthreading) and the TWELVE on the 980x. The first dual-CPU machine I got was a Powermac Dual G4 1ghz...back in the day, that thing would FLY through seti units. Now, it wouldn't stand a chance against the lowest end CPU I could buy. I remember watching in awe as my first 64-bit CPU (AMD Athlon FX-57) crunched through work units at its overclocked speed, thinking "man, how will it ever get any better than THIS??". I dunno, every time I get a new CPU or GPU for seti, it feels the same as I felt on Christmas morning when I was a kid. I'm always so excited to get it installed and letting it start crunching. I watch in awe as the little progress bar moves. Seems like every time I add something new, that little bar moves faster and faster. Pretty amazing stuff, if you ask me. I, for one, can't wait to see what happens in the future with the whole CPU/GPU in the same package...that's going to be a ton of fun when AMD throws their hat into the ring. And what's after that? Who knows? But I can't WAIT to see it, to put it to work crunching for seti! Very exciting times we're living in here, folks, very very exciting! -baron_iv Proud member of: GPU Users Group |
