Just got this up and running over the weekend!
---------------------------------------- Over 22GHz of AMD crunching power in one box:From the front: ![]() A little closer: ![]() The back-side: ![]() Cooling: ![]() BoincView: Parts used: 4 DFI motherboards 4 Fortron 400w power supplies 4 dual-core AMD Opteron 165’s @ 2808MHz 4 sticks of Kingston 512MB RAM 4 miscellaneous HD’s 4 Swiftech Apogee waterblocks Swiftech 3x120mm rad Swiftech MCP-655 pump Swiftech Micro reservoir Buffalo wireless ethernet bridge I still need to mount the door and paint everything but it's up and running great right now, cranking out 50+ results and 20,000+ points per day! Maybe once quad-core CPU's cost less than $200 I'll build another one...lol! ![]() |

Wow, that's a nice little cruncher!

I believe 'giga-flops(Floating Point Operations Per Second)' is a more accurate measure then 'giga-hertz' but, still pretty impressive. (An old argument AMD made against Intel long ago)
Olympic, I am curious as to how you interfaced and connected all them motherboards? How does it all tie and work together? I see the ethernet bridge yet I don't understand. I'm not familiar with how to connect motherboards to work together into one interface. Are they all controlled by one computer and all the results displayed on one central monitor? I'd probably think about building one myself if I understood how this works. I have only built single machines. Do they all use seperate hard drives with operating systems? Thanks Randy |

Making a faraday cage using brass/metal mesh like the myth busters did to keep noise and microwave radiation out? I Wonder if the components are shielded enough internally or if using a cell phone nearby would cause errors or crashes? I know a computer case is usually metal and thereby shielded. I don't suspect it would be a problem but, just a thought. |

All 4 systems are seperate, the same as they would be if they were installed in their own case. There's 4 power supplies, 4 hard drives and 4 operating systems. The ethernet bridge connects all of them to my home network for internet access. About the only reason I stuffed all of them in one box was so they could share a cooling system. I guess I can admit that the "cool factor" played a part as well.
---------------------------------------- Each system is pretty much autonomous. They will happily crunch away for weeks at a time with no input from me. I use a program called BOINCview on my main computer to monitor the status and progress of all the computers on my home network. If one of them goes offline, I'll know immediately and can take action to correct it, which usually means a simple reboot. Shielding is a non-issue. The metal in a computer case is more for grounding than shielding. You'd need some pretty strong RFI to cause a problem with a computer. ![]() |

Nice!
That's some serious devotion to crunching! Which reminds me, I must upgrade my main cruncher soon... |

I guess I can admit that the "cool factor" played a part as well. wink Each system is pretty much autonomous. What you did is just what I've been looking at to do myself. Recently looked at rack mounting but the systems have to much AC power, memory, video when looking at servers. I'm just now looking at small Single Board Computers (SBC). So, . . . . . I've much decided on buying, like you did, mother boards (MoBs) or SBC's and installing into a rack like you've done. You've done a great job but now that your project is completed what would you change for better efficiency? For instance, 400W PS's seem like overkill for each board and consume electicity produceing much heat. 230W seems better for both consumption and cooling or one PS supplying power to two or more boards (cut costs) ? Add 512GB memory sim for other projects. Keywords -- scale up expansion? Do you think we should ask the Aministrators to start a new forum "WCG HW Builders" for HardWare builders where we could interact, maybe join purchases for cheaper prices, pass on knowledge, etc. ??

Hi PTabolinsky,
There is another distributed computer board with an active Hardware forum that covers all the distributed computer projects - The DC Zone at http://forum.thedczone.com/ Lawrence |
