2) Message boards : Number crunching : Best credit-per-watt platform? (Message 825684) Posted 1 Nov 2008 by Paul Hayslett Post: You folks are the best. That's exactly the kind of info I wanted. I'd been seeing fan-less embeddable boxes in the 5W range and couldn't get them out of my head. Like this one, which is more $$$ than I want to spend but I like the form factor and power use. I just had no clue about the AMD Geode and how it would crunch. Based on all your responses, I think I will just do the Cheap-n-Cheerful thing and forget about the low-power boxes for now. Thanks again!

(Message 825563) Posted 1 Nov 2008 by Paul Hayslett Post: This is my Cheap 'N' Cheeerfull Crunching Box. http://setiathome.berkeley.edu/forum_thread.php?id=49285#806872 ... It was that thread that got me started down this path, actually. I read it and got to thinking how I really don't high-end disks, network cards, etc. just to crunch. I'm burning watts for stuff I don't use. And I'll probably end up building something along the same lines. I just wanted to check first whether anyone had experience with mini- or nano-ITX form factor boards. Some of these can be used to build fanless systems drawing very few watts. You could stack 5 or 6 little Linux machines for $500. I just can't get a handle on performance. Has anyone used these?

If your kitties are anything like my 3, they will sabotage any attempt to head in a low-wattage direction. Nothing the cats like more than a warm box to lie on. They probably saw my post and scrambled the logic. [I'll admit that I was hoping that the answer to my query would involve some no-fan enclosures. That would have meant an end to the quarterly clean-the-cat-hair-out-of-all-the-heatsinks chore.]

I did try "search" before posting. I guess I didn't hit the right combo of keywords. Thanks for your help. Paulie

6) Message boards : Number crunching : Best credit-per-watt platform? (Message 825303) Posted 31 Oct 2008 by Paul Hayslett Post: I'm coming up on 2E6 SETI credits (well past 2E6 for total BOINC) and I'm starting to feel guilty about my power consumption. I'm thinking maybe it's time to let the big boxes power down, replacing them with something less carbon-intensive. The question is: what? I guess the first part is: am I better off going for one over-clocked quad or multiple low-power boxes? Are the new quads so much faster than power-sipping, embeddable SBCs that I still get more credit/watt at the high end? Or could I put together a small stack of 5-watt machines which approach a high-end box in throughput? The second part is: how low can I go, consumption-wise, and still help the SETI cause? What kind of RAC can I get for 5W? 3W? 1W? These boxes would only crunch for BOINC -- they don't need any sort of fancy graphics or big hard drives. Yes, I know I could do my own research on the SBCs available. I'm not asking you to do that work for me. I'm just hoping someone here can give rough estimates off the top of his head and save me a little time. I am totally comfortable building my own boxes. My money isn't infinite but I'm willing to spend a few bucks to help the planet. TIA.

Slowly but surely my upload queue is shrinking and WUs are trickling down too. Thanks for making it happen!

Now down to 45. WUs have been trickling in. It seems like bruno is slowly catching up. Eric really rang the bell with that config change.

Didn't you know that tidying up causes bitrot? The table which we sit around and eat lunch ... And who gave you permission to stop and eat lunch? If you have time for that then you obviously aren't working hard enough. ;-) Seriously, you folks deserve much more praise than you get around here. You've got an awesome uptime record spanning years and years. We'll wait patiently until things are back on line.

I hope that means whatever was broken is now fixed and everyone else's clients will get new work soon. The SETI crew can brag that they beat Rosetta today. R@H is still wedged tight.

Cycled the router, flushed the caches, no joy. BUT, Matt shouldn't waste his time looking at the SETI servers. I'm getting the same thing at Rosetta, starting at the same time. So the problem must lie elsewhere.
