Quad GPU Folding Rig v2

Postby klasseng » Fri Oct 12, 2012 11:14 am

A number of years back I had built up a Wintel box dedicated to folding. I had started with some 9600GSO"s and eventually upgraded to GTS450's. Then this spring it became unstable with repeated blue screens. Just as well, it was a warm summer and I didn't need the extra heat in the house.

Now that it has turned colder, it was time to get it back up . . . with an upgrade:
ASUS Rampage IV Extreme motherboard
Intel i7, 6 core, 3.2Ghz
16GB RAM

Kept the same 850W power supply and the GTS450"a

Will see the points jump today, I hope, I hope!
peace,
Grant

Sounds impressive indeed! Let us know what the result is :wink:

Last two weeks with:
1 X Mac Mini Core2Duo
1 X MacPro 8-Core Zenon
1 X Dell 4 Core Intel
about 33,000PPD combined

Friday, first full day of the new Quad GPU Folding Rig v2:
All of the above machines +
1 X 3.2GHZ Intel i7
4 X GTS450's
96,783PPD combined

I'm already looking ahead to the next upgrade, waiting for:
a) F@H support for the new Kepler GPU's (they sort of work, but not great points)
b) price drop on something like the new GTX650TI

Awesome! Takes me a week with 3 machines to match your latest one for a single day 8-)

It's difficult to make firm calculations, depending on the WU mix that's available from day to day or week to week, but the rough numbers are:

Before the quad GPU/6-core i7 CPU kicked it was around 33,000PPD.

After the quad GPU machine has been running for a week it's around 95,000PPD.

Because some WUs are quite long (>18 hrs) there's quite a bit of fluctuation. Some days as little as 70,000; I've observed some 24hr periods have had more than 120,000 points.

Did you happen to read [url=http://folding.typepad.com/news/2012/10/unified-gpusmp-benchmarking-scheme-equal-points-for-equal-work.html]this blog post[/url];

[quote]OCTOBER 21, 2012
Unified GPU/SMP benchmarking scheme: equal points for equal work

The current benchmarking calculations for SMP and GPU projects are performed on different machines since originally the SMP cores could not perform the calculations that the GPUs cores could and vice versa (GPUs were only for implicit solvent calculations and SMP only for explicit solvent calculations). With recent advances in both cores and completion of our testing of these capabilities to ensure agreement, we are now confident we can do the same work on both cores. Thus, we feel that it is time to unify GPU and SMP benchmarking, both for simplicity and fairness.

In order to complete the move towards this plan of "equal points for equal work," new GPU projects will be benchmarked using the existing SMP benchmarking scheme. Based on our internal tests, the end effect of this new, unified benchmarking scheme would boost the points for the GPU projects, both in terms of base points but also by bringing Quick Return Bonuses to GPU clients. In order to test the new scheme, we have started a GPU3 project (Project ID: 8057) and released it for beta testing. Once the benchmarking scheme has been tested, all the current GPU projects will be re-benchmarked to reflect the changes in the benchmarking scheme.

Awwwww yeee-ah! Looks like my old MSI K9A2 Platinum quad GPU rigs will be brought out of storage and upgraded for some GPU lovin' once again! I wonder if they make a PSU capable of handling 4 x GTX 690 in a single machine? 8 cards total plus ~250K points each equals an insane amount of computational power (and heat with noise)! Things that make you go hmmmmm. :rofl:

Surely it must be possible to put multiple PSU in a single machine :rofl:
Actually, I remember seeing that somewhere on the net :idea:

Yes you can, but I just wanted to keep it simple. I will have to see how much a single GTX 690 pulls at full load first, then go from there. Might have to take a serious look at an [url=http://www.techpowerup.com/mobile/reviews/EVGA/SuperNOVA_NEX1500/1.html]EVGA SuperNOVA NEX1500[/url]. :)

That thing costs more than my entire machine :D Looks pretty sturdy though 8-)
