Wiggo, We found you a new heater for the 'shed' :D Although your solar array may need a tad of an upgrade! |

Wiggo, We found you a new heater for the 'shed' :D I like to be warm, but not cooked. :-O Cheers. |

Wiggo, We found you a new heater for the 'shed' :D I don't know. It's probably only about 50KW or 180,000 BTU. That's only like 100,000 BTU more than the furnace in my home... I'd ballpark a RAC of around 8.5-9 million. SETI@home classic workunits: 93,865 CPU time: 863,447 hours Join the [url=http://tinyurl.com/8y46zvu]BP6/VP6 User Group[ |

I'll take up some of the slack. Just brought 7000+ cores online on SETI@Home. The reason why is hilarious, but unfortunately I can't share it here. Yupper, I just looked and he has 255 computers online mostly with 32 cores / motherboard. Apparently many are just starting so the RAC's aren't anything to write home about. Yet. On the other hand, most of his computers don't have gpu's crunching. So as soon as someone starts donating say all their old GXT 750 Ti's to him...(they all upgraded to GTX 1060s) things will move up even faster..

Read the article also, and after your post checked this website statistics page: . . Maybe someone did some housekeeping on the database and some of the gunk fell out .... :) . . For many contributors there is a fine line between active or not ... Stephen ?? |

Sadly, this. It to me is somewhat of a similar correlation to what we are seeing in retail, big box traditional retail is dying a slow (but seems to be accelerating) death due to pressure from the online retailers who are catering to 'lazy consumers', having found ways to now even offer same day delivery on a growing number of items, and similarly PCs and notebooks are going in the same direction. Not that either brick and mortar stores or PC's will go away anytime in the foreseeable future, but both will continue to lose market share, and on our side of things, even if mobile BOINC apps become more common and powerful (if they even exist, as I have no idea, I don't pay attention to that side of things, I'm a PC guy) I seriously doubt that they could process tasks at anywhere near the rate that a decent powered PC could due to all their limitations- battery, processor, effect on system performance would be a few guesses. Just my .02 on it. . . Hi Al, . . I'm wid you! I like a nice powerful PC with a screen I can read and a keyboard I can type on. But there are lots of ppl testing and using BOINC/Seti apps on mobile devices. The return rate from these devices is about what you would have seen from the average desktop 15 years ago so I don't think they represent any serious alternative to the traditional desktop PC for processing Seti data. But the number of ppl moving to using such devices may greatly reduce the numbers of people like ourselves who are doing their best with much more powerful equipment. It could come down to a split between the serious geek crowd of crunchers and the general populace. But with the millions of mobile device users if a significant percentage adopted Boinc/Seti it could add up to a sizeable contribution overall. . . And being a bit of a troglodyte I also like to shop in person ... :) Stephen :) |

I personally know of 11 friends who are former hard core crunchers for Seti and they invested a lot of money on high performance multi GPU equipped rigs. But they felt their contributions to the project were not appreciated after the introduction of Creditnew (also known as credit screw!). They found themselves crunching the same amount of tasks as the previous week but for half the credit and got disheartened. They are still crunching for other projects with more generous credit schemes. . . Hi Chris, . . I can sympathise with your friends' feelings but really, it is about processing as much data as possible and finding E.T. It is sad they do not share that dream. But there are many worthwhile science projects on BOINC so hopefully they are still doing good. . . Somehow I doubt that CreditScrew will get fixed any time in the near future. :( . . In the long run it does tend to average out though. Stephen <shrug> |

. . Hi Tom, . . I only counted 225 but it still makes him a contender and serious rival for BojanR :) . . There are 2 with GPUs and I suspect they are personal rigs or supervisor terminals. I also suspect the others are in an environment where he cannot upgrade them with GPUs. . . Nonetheless, 223 rigs crunching on say 30 cores, getting through a WU in an average of say 3 hours, at an average of 95 kermudgeons. . . <licks pencil tip> 223 * 30 * 24/3 * 95 + 40,000 (for the supervisor terminals) = 5,100,000 approx. Of course if he can only crunch on half the cpu cores for logistical reasons then a mere 2.5 million RAC. BojanR should definitely feel nervous :). Stephen :) |

Impressive farm there Jaun, tasks are starting to validate now and showing what is possible out of it. It definitely beats your typical 60k/day RAC :D FreeDC Stats: How long do you plan on leaving it run? It typically takes weeks for the RAC to average out. |

How long do you plan on leaving it run? It typically takes weeks for the RAC to average out. 6-8 weeks. It would be interesting to see how it goes over a 3 month period (to allow for unexpected outages and the like). And running stock it'll take a few days to pick (hopefully) the fastest application.

Wiggo, We found you a new heater for the 'shed' :D I only want to keep 80 cubic metres of my shed warm, not all 460 cubic metres of it, so yes I'd be well done in no time. :-O Cheers. |

I'll take up some of the slack. Just brought 7000+ cores online on SETI@Home. The reason why is hilarious, but unfortunately I can't share it here. Something like management want to stress test the disaster recovery site? Sounds like more cores than the Atlas cluster that Einstein use. They aren't the latest kit but a year or two old judging by the Xeon v2 and v3's. Hate to think what the electricity bill would be like. I need a shed like Wiggo, my loft gets too hot even in winter 😩 BOINC blog |

Speculation is pointless, I have a good reason to do this and SETI@Home serves the purpose. I may do more, as this is only a few racks in one row of several in my data center. It's only temporary, will end when it ends. Enjoy the fireworks. I will say that I am not interested in competing against anyone. I just happen to like SETI@Home, even though I know the odds of it finding what it is looking for are infinitesimal. |

Stephen, agree, maybe if we get all those millions and millions of smartphone users crunching, it will eventually add up to a big number, who knows, though with the limitations stated above, battery above 90%, plugged in, who knows? And I am with you, all things being equal, I like to lay my hands on things before I purchase them too, unless it's a commodity item, but for big ticket ones, strongly prefer local, do more easily deal with the inevitable issues. :-)Sadly, this.

Smartphones apps are a really good mean to get more people interested in Seti@home, for those out there (Millions) that don't even know that Seti@home exists. Then, in addition to crunching on their smartphones, some of them who get really interested in the science could also use their Personal Computers to crunch. There is a lot of cumputing power out there to be harnessed. |

Maybe it is Marketing that is required. Based on searches for 'tech' products, to push ads for a FREE way to donate to the cause. |

It's only temporary, will end when it ends. Enjoy the fireworks. Oh don't get me wrong I'm in this for science and am more than happy you've dedicated your machines to the search. I'm just a little envious of your data center compared to my small farm. Unfortunately I'm constrained by available space, power and finances. BOINC blog |
