Did any of you guys ever think about CUDA and backplane risers a la compute cluster for folding?

I haven't seen any of these setups yet but I'm curious about it.
The possibilities are endless :p Moar density!

I found this: https://bitcointalk.org/index.php?topic=64450.0

Guy couldn't get it to work, probably because he was using radeons, but if CUDA clusters are built like this, then a CUDA folding/mining cluster is ought to work, right?

:comp:
 
I haven't seen a backplane folder set up. 12 GPU's sounds like a ****load of power would be needed. A 20A circuit wouldn't do it, so you'd need to change from the normal wire size, etc.

Anything that requires hacking the BIOS and the Linux kernel, is a project that is beyond my abilities, even if I wanted to set it up.
 
It looks like it'd be the ideal setup for a super dense compute cluster.
I'm working with an investor with deep pockets, I'll see if I can get a dev to work on this.
If I get a working os and a part list I'll post it here for you guys.
 
A stand of mobo's, with 6 GPU's each, isn't dense enough? (a la Atlas Folder's first set up on YouTube)?

You could spend a lot of time and money on getting this cluster to work, and there are real doubts that it would ever work at all. Compare that to using a known method.

There is a reason backplanes are not more popular. My one experience with a multi-board backplane computer was FAR from being a dream. (Quite the nightmare.)
 
Was just wondering...6 gpu per board is good but even that can get hard to pull off. :p
I was going with 4 per board, using server fans and no riser cable nor adapters, all that chinese crap parts tend to burst into flames eventually.
 
Honestly, it's been several years since I saw Atlas Folder's old gpu "farm". I am not sure if he had 4 or 6 GPU's per mobo. Six does sound too high.
 
Good.

I'll build at least 24 rigs with 4 r9 290 with risers cause I couldn't find boards for decent $$.
I chose the msi z87 g45, which takes up to 6 gpus with risers.

Isn't that going to cause a tremendous load problem on your home electric power panel and circuits? (Not to mention the cost.)
