The Official Team TPU Crunching Farm Planning Thread

[Disparia]

10 blades per unit, 4 cpus per blade, 12 cores per CPU (Opteron), so 1920 cores per rack.

Oh, was this thread not for imaginary farms? Well in that case I recently added a 'core' towards WCG recently, giving FAH and WCG two cores apiece. :/

Man, I was thinking to myself "my god, how in the hell can anyone afford 1,920 cores for crunching let alone the cost of utilities

And then I read below the image
Good one Jizzler!!!!!

 

[Disparia]

Yeah, I haven't won the lottery yet. But if I did, would certainly dedicate a rack each to WCG and FAH.

For the FAH rack, hmmm... probably 56 GPU (8 per 4U) and 96 CPU cores, keeping the same UPS and switch.


Hey, what part of Wyoming are you in? I have an aunt and uncle in Riverton.

About 200 miles away in Cheyenne. Awesome seeing someone with relation in Wyoming. Been to Riverton many times. Several times to watch the balloon festival!!!

 

[Disparia]

I haven't been there in... wow... 14 years. But my wife, kids and mom went to visit recently. In fact, they went and saw a balloon festival!

Last time I was there I attended some some festival as well. Parade, classic cars, and a burn-out contest - even got a piece of rubber from a blown out tire that hit my face as souvenir

Also camped in the mountains near there. Was memorable as the rainbow trout were quite tasty. I could really go for some fresh caught fish right now.

SandyBridge chip will do 9 WCG points mer MHz so @ stock 3.4GHz will do ~4372 PPD. The Gulftown does a little more work per MHz so at stock speeds should still yield more PPD. But for crunching the SB makes more sense since it consumes so much less power for 24/7 use.

Well, lets have some watt figures to go with it - 970 @ 4.1 GHz takes around 270 W from the wall and produces around 7500 PPD. (and it does 62 kPPD at folding)

I presume you mean this is a dedicated rig? It would work out as:
7500/270= 27.8 PPD per Watt

A dedicated Sandybridge at 4.6GHz draws 155W and does ~6000PPD (But this is only comparable if the one you mentioned is dedicated too):

6000/155= 38.7 PPD per Watt

thanks, i have been thinking about making a rackmount server, depending on my job career choice.

I was thinking of something around these lines

Looks good. But thought I'd mention: H series motherboards don't allow you to OC the CPU so you might as well save a little and get the non K version. If I assumed correctly that you want to run at stock speeds on this for stability reasons?

If my deductive skills are weak and you do want to OC, you'll need to get the P series version of the motherboard (with K cpu)

well i was hoping to use the H series so i don't have to get a graphics card. so i can use the onboard graphics of the cpu. and with turbo boost at 3.8Ghz i think it will be good for stability so no OC. I would love to get one of these and fill it up

I would love to be able to have something like that too. I think Jizzler's post is coming to mind again..

As for your blade/rack the H makes perfect sense in that case. If you do go for K I suppose it will be easier to re-sell at a future date if necessary. Your components look perfect to me in that case.

 

[Delta6326]

Yeah thats where i kinda got the idea but this won't be a anytime soon project. as i need to get many things done such as college and get a high paying job.

All the best, then

Multiple motherboard gravity flow water cooling system.

Was thinking about it as I have a radiator I never got around to installing in my van, it's a little larger than 2' x 3'. Could attach a $20 box fan if the heat generated demanded active cooling.

Would use N + 1 pumps, so it can survive a failure.

Now I just need like... 20 systems or so to try this out on, and the cheapest blocks I can find

I plan on upgrading my 2 X6 1090Ts when the Bulldozer/Zambezi chips come out next month. If they really perform as well as expected (should kick ass on floating point operations), I might even replace the i7-920 or possibly the 2600k's. Both chips are still current enough that I should be able to sell the chips and boards to help offset the cost and I can recycle the memory.

But we'll have to see. AMD is keeping performance stats close to the vest as of my last search about a week ago.

 

[Chicken Patty]

interesting stuff guys. I never got around to upgrading but if I stop having surprises, I might just be able to build another rig.

 

[KieX]

Downsizing my farm for summer. Like others here, heat is a massive problem. So I've sold my sister's E6300 and put one of my 2600K in her computer. Plan to sell the i7 930 I have at work too.. so I can move another of my 2600K's out of my room.

Essentially I'll be down to 3x 2600K's. One is my sister's, the other is at work... leaving me with just 1 in my room. Think I can manage to sleep in a room with just one. This move also frees up the other shelves for winter

 

[Chicken Patty]

Any update guys, thread has been dead for a bit, I know there has been some new builds and plan since the last post.

 

[KieX]

Got an i5 2500K coming tomorrow. Will be the last cruncher of my current farm. It's the perfect balance for me in terms of electricity cost and heat.

The E3 Xeon's can be great buy's for stock clockers. My every day rig is an E3-1230 (which is a good buy at about $230) and it gets 4,000 - 4,500 or so. Plus I didn't have to spend on a fancy mobo, or cooling fan or have to deal with crashing issues. Overall a good buy for a no hassles cruncher. A bunch of those in micro ATX boards with basic air cooling and ram would make a nice efficient easy to manage farm.
