12core AMD ppd? - Page 2

Are you suggesting to make a 2600k cluster or? I'm confused because I thought with bigadv multiplier scaling for earlier completion its better to have one system with the same power as 2.

I may punch numbers on this later and see what I come up with at work atm.
Thx for suggestion.

Get an SR-2 build with two 6 core Xenons, and 3 or 4 580s and you'll have a massive folding rig

kinda making a cluster - but not really as all the machines would be separate.

A single multi-cpu setup running 1 client can get a lot more points, but at MUCH higher cost. Take an SR2 rig for example - you can get ~120k ppd from one system, but for the same money you can build 3 (maybe even 4) 2600k rigs that will do almost 150k ppd (or 200k if 4 rigs). Any other multi-cpu board aside from the SR2 doesn't allow overclocking, and so the ppd there is even lower for the capital costs.

I been thinking of this for a while now. I think you can buy a G34 quad socket board and use Bulldozer chips. Im waiting to see what kind of PPD thats going to give with up to 16 core cpu's.

There are lots of threads about 48-core folding on folding forum... a few points from there.
  • 200k PPD a day would be stretching it, but you might get close to that.
  • The issue is not how much ram, the issue is populating every slot on the board. (Not cheap with Reg ECC Ram)
  • You should probably just buy the Supermicro barebones server then just add Proc. and Ram (Its power supplys are more than enough)
  • SMP doesn't scale that well and it looks like 64 cores is the limit currently. Then you have to run multiple instances.
  • Nobody is actually running a cluster... just multiple machines (as mentioned earlier) HPC setups will not run the client properly and they cannot effectively move instructions between machines so it is not efficient.
  • It boils down to $8k min for 200k PPD.
  • 2600k can do at least 50k PPD for ~$600
  • Build 4 of them... Profit.

I know this because I was getting ready to build 48-cores to fold on. I have pricing lined out that blows newegg away and it's still not cost effeicient. (I really do want to build it anyway)

(I don't live in the US, but I hope I've done this right.)
  • 12 core build:
  • 4 x $770 = ~3000 on cpu's
  • 1 x motherboard = ~$600
  • Memory = ~$800-1200
  • Harddrive, powersupply, case = $250
  • Total: ~$4500,-

Let's assume 4 Intel 2600k would outrun this machine by about 20% if overclocked to around 4,5Ghz. Should not be a hard job.
  • 4 x 300 = $1200 for the 2600k's
  • 4 x 150 = $600 for P67 motherboard
  • 4 x 45 = $180 for harddrives
  • 4 x 100 = $400 for memory
  • 4 x 50 = $200 for cases for the 4 motherboards
  • 4 x 80 = $320 for some medium/good powersupply's.

Total: ~$2900 dollars

Those opteron's run at such a low speed, those 2600k's can outrun them twice with better clock per clock performance. It's cheaper, might consume a bit more power but more effective.

I've been looking at doing this for a while and can say after all the cost comparisons I've done, the 2600K system wins out every time. I brought my costs down even further than listed above by not using cases and instead mounting each on a rack stacking them to save space (got the idea from a post on this forum, can't remember where it was but I will look). The mb I picked is the ASRock H61M-VS LGA at only $60 each that got great reviews. There isn't much need for a beefy power supply as you aren't running much on it. I picked up my psus and hdds form a local computer surplus store all brand new for very cheap. When I broke it down last time I think each setup will run me around $530.

Tear is getting <6min TPF on his 4p MC system foldingforum.org/viewtopic. So in theory that's 448K PPD.

You can read more about it here, here and here.

Plus you don't need ECC Reg memory on a Suppermicro motherboard, second "here" link above. Also only 4 of the 8 memory slots per CPU need to be filled.
