8 GPU system possible running from home power socket?

[Jules123]

Hi,

I have a need to put together a research compute machine consisting of 8 NVidia Titan cards that will be running CUDA. All this running from normal house power socket(s). If it can play games off a multi-monitor set up too, that be good.

Budgets are relatively tight so don't want an expensive enterprise solution. Water cooled be good, can imagine it's going to generate some heat though, not to mention electricity bills.

All the GPU cards must be running off one host computer. So I'm looking for a solution that is more prosumer and I don't mind a bit of DIY.

Thanks for any help,
Jules

I hope you live in a detached house (Preferably in the middle of nowhere) As when its fully populated and running flat out it sounds like a 747. The fans are about 2" thick and are paired up..

Everything goes up in the attic conversion, no problem up there. Maybe keep the birds awake though?

I also noticed that solutions can't fit eight cards, Titans are dual slot, or am I missing something?

The stuff I am doing will be compute intensive so I don't think older cards are going to cut it. I'll be also using dynamic parallelism in CUDA supported only on GK110s.

How does a 16x to dual 8x riser work?

Cheers,
Jules

The PCIe slots are spaced in 2 slot intervals so you can fit 8 cards. The one that is currently in test has 8xTesla K20's in it. I have also tried it with 8 x GTX 680.

Okay, I get it, 2 slot spacing.

I didn;t think it would be possible to do all this on one computer. Can you elaborate more on the cooling? Do you know what temperatures you were getting? Did you OC the cards?

Cheers,
Jules
