Has anyone tried this? I found this guide regarding Folding@Home. Just wondered if it would be a good way to save power, especially with how much idle GPUs are using.

Yes, a team-mate of mine done this in April/May on a large scale, saving the instance to central disk if the device was needed for other purposes, PXE/linux environment. Initially there was a conflict issue of duplicate client IDs, but with some change and a faster retry setting by the WCG tech, server side, he was on a blazing trail.

Thus, suitable for docking, comparing, folding, matching, seeding, positioning you name it in a grid computing ambience.

What's more, with BOINC, multiproject and not only with a proprietary client doing just one thing.

Every so often when one of my servers stops being used as a server I use a USB-boot ubuntu distro. I run boinc on it. I can disable lots of things like the CD and hard drives.
----------------------------------------All it takes is a single 2 gb flash drive, a motherboard, a powersupply, RAM and a CPU. [Edit 1 times, last edit by Nick-MMX at Jun 2, 2009 12:17:45 PM] |

Thanks. I think the Flash drive option might be the best for me although I've never used Ubuntu before. Is it easy to do?

Well.. you do have to know how to use the command line in a limited way but mostly ubuntu it easy to use, First you order (for free) a ubuntu live cd (or download from the internet). You then boot it up and go into system and then administration and there is a option to make a usb bot drive. Once it has made the drive you download the boinc client from the boinc website. You then copy this to the flash drive. You then double click the install file which you copied onto the flash drive. You then go into the terminal and type: cd /media/Something(just push tab usually)/BOINC
now you type ./boinc you then open a new terminal while keeping the old one open. In this new one you type: cd /media/Something(just push tab usually)/BOINC Then you type ./boincmgr This opens boinc like normally and lets you do whatever you want. |

Hello gibbcorp et.al., I have not tried this exact image, but built my own. "notfred's" instructions seem sound at first glance, and because I like getting under the hood and tinkering on my own, there are a lot of moving pieces 'software-wise' that have to be correct in order to work. The image(s) I use are quite a bit larger than his and I run into NIC driver issues once in a while. I built it all with power consumption in mind and YES! It pays off. Add ten machines minus ten hard disks = quite a bit of energy savings. I started to do the math, but saved it for the monthly electric bill  It's still affordable for me.P.S. I run it (almost) entirely out of RAM and there are limited WCG projects that fit in the smaller space requirements (e.g. HCC, Rice), prepare for a busy network switch...

Hello yes there is a very easy way you can do it. Do this: go to http://drbl.sourceforge.net/ And follow instalation instructions. It is very easy to make. After that
----------------------------------------go to /etc/drbl/boinc-url-authkey.conf and type the URL and boinc key (found in account settings) http://www.worldcommunitygrid.org YOUR_KEY then do /opt/drbl/sbin/drbl-live-boinc Note ubuntu 9.04 is not supported, I use 8.04 because it is LTS It takes some fiddleing though. Also that 1000Mbps can do about 10-16 computers only after that the lag starts to timeout various operations. Mostly at boot. I made my setup more isolated from the rest of my network by making a really long cable to increase lag. That way any tftp and dhcp requests from the nodes never make it outside the setup or vice versa. If you need help i would beglad to help! But the DRBL website is pretty over informative hope this helps Oh also note that if you DO decide to use a flash drive setup to be vary careful. Flashdrives have a limited number of write cycles. Try to get a good drive or set init to copy all to ram before booting and rsync to disk a backup every so often. I am doing an experment currently with how long a flash drive would work in this setup and so far no bumps. (modern ones have nice load balanceing) [Edit 1 times, last edit by Lightningrunner at Jun 2, 2009 11:41:14 PM] |
