Has anyone here run the Folding@Home SMP client on a Core i7 system? And if so, could you provide numbers as to what the PPD is for whatever CPU, OS & system configuration you have?
 
I don't think anyone on this team who regularly posts built one yet, but a number of people mentioned they were planning or thinking of doing so in the near future. Although I seldom build single socket systems, I am also very curious to see some [H]ard i7 F@H numbers.
 
There is grea thread over at the FoldingForum.

You cant hardly compare crippled windows with a1 cores to Linux and A2s anyway.

I realize that this thread is titled i7 920 but I thought some might be interested in i7 940 output.

The computer is using Ubuntu 8.04 and running @ stock with the -smp 8 flag and HT on.

I tried Intrepid but the PPD dropped to around 5400. Apparently from what I've read so far this drop has to do with the later kernels, but I can't say for certain that is the cause.

Where is he getting his Q6600 numbers at?? Mine at 3.6 running two VMs of Ubuntu 8.04 are each producing close to 3100PPD. Thats while also feeding two 8800GTs.



 
The ppd with ubuntu 8.10 is quite a bit lower than 8.04. I remember reading it had something to do with the newer kernel and f@h not maxing out the cores....

Does that affect even the distros that are based on Ubuntu??
 
I think so yes, I've also heard that it effects fedora core 10 (and possibly 9) as well.
 
Core i7 920 OC'd to 3.4 GHz with HT on and SpeedStep Tech off with Ubuntu 8.04 Server:

Averaging ~3m frames and showing 9000 to 9200 PpD on 2669 and 2671 WUs. * As reported by FAHMon.

Those are some really nice numbers there Tobit ...

We need to get some $$ and power figures so we can see how this stacks up with the GPU2 clients ...

Probably quite favourably. A 130W TDP chip kicking out 10k PPD is actually probably more power-efficient than GPUs considering there are no single-GPU cards capable of that much production. It would take something like two 9800GTs or GTXs to put out that many points, and even one of those cards would probably use more power than a single i7 CPU.
 
Since I don't have any nVidia GPU, I had to look up Kendrak's Stats on his 9800GX2
Each Card was getting 9400 PPD (4700 per Core)

So on the PPD area ... it is about even ...

I think in the end, it is cheap to go with the GPU, but building a new system a Core i& base would be a good foundation ... wish the motherboards were cheaper ...

Yeah, the cheapest i7 920 combo I can come up with for dedicated CPU folding (at NewEgg) is $563.00 - CPU, mobo, and a single 2GB DDR3-1333 stick.

I never intended for my Core i7 purchase to be used for dedicated folding but, there it sits *points to corner*, folding away without a video card installed. I must be addicted. Next pay day (Feb 3), I am either going to add 6 x 9800GT's or a couple 9800GX2's. I want to go with the 6 x 9800GT's just so I can say I have 6 video cards in the box but it might not be the most efficient way to go. :rolleyes:
 
Man, how much do you get paid Tobit??? I wish I could afford that amount of hardware every payday!!!

Not that much really and pay day is only once a month. :p It's called being single with no other bad habits/hobbies and very few bills.

Why not just go the extra mile and load it up with three GTX295s? :D

Because I am not as rich as lelliott731 thinks I am. :p $1500 is a bit much, for me, to spend on GPUs for folding. :eek: 6 x 9800GT's for $600 is bad enough. :rolleyes:
 
Wow those are some seriously impressive numbers. As others have said, if the MoBo's weren't so expensive, I'd go this route :)

Better to go with three 9800GX2s than 6 9800GTs actually, since they have more shaders. That is, assuming it's feasible for you.

Only issue seems to be finding three 9800GX2s. The 'egg used to have the PNY 9800GX2 for ~$234, but they've been sold out for a couple of weeks. It hasn't been deactivated yet, however, it IS the only remaining 9800GX2 on the 'egg. Other websites start at $500 for the 9800GX2. If you're patient enough (which I am certainly not that), then you can find them through e-bay or FS forum

Yeah, I will probably just go with 2 x 9800GX2's for now.

Back to the Core i7 topic, I have 18m left on this WU and then I am going to shut down and try and push my overclock a bit harder. I'd really like to hit that 10K PpD mark. :cool:

Quite true. However, NewEgg is still listing two 9800GX2's - one from PNY and one from BFG.

That's what I meant when I said if it's feasible. If they can be found, GX2s are the ideal price/performance folding cards at the moment.
 
Wow, I remember those days, but now I am married, with a disabled wife who can't work, and I myself have a few medical problems, so our medical bills are sky high. I've had to go from having a hundred or two every month to spend on hardware to about $25 a month, so it'll be a graphics card a year or so for me. Unless I can find people willing to let me run it on their systems, which some people have been kind enough to let me do, but so far those have only been P3's and below, but anything is better then nothing!
 
Here are some benchmark numbers on the last three projects. With HyperThreading enabled, I can't overclock my CPU any harder that 3.4 GHz and fold stable. I get kernel panics on some of the HT "cores". It's not worth it to me to run without HT. However, it might be an interesting test someday.

Very impressive numbers Tobit! Thanks for posting. What kind of cooling do you have on that i7?

Noctua NH-U12P SE1366 - My weak overclocking isn't caused by any thermal issues as I am able to run some Windows based overclocking tools at clock speeds much higher than this and still achieve reasonably temperatures with HT enabled. Many times, the kernel panics occur during the actual booting of Linux so it might be an issue with the kernel revision I am using. I'm on Ubuntu 8.04 which is using a much older kernel than I would normally like.

It's pretty stable at 3.4 so I am fine leaving it like this for now.
 
Yeah, I can't wait to get my box set up this weekend. So Tobit, you are just running Ubuntu 8.04 only? And how many SMP clients are you running?
 
lelliott: Unbuntu 8.04 server only, no updates done to it. Only one smp client with the -smp 8 flag and advmethods and bigWUs set in the config.
 
Looks like I might have to dabble with a Linux VM and the SMP client this weekend...Replaced the Q9450 in sig with a i7 rig and loving it. Mine's only (only!) running at 3.2.
 
SatTech: Let me know how that goes. I was pulling my hair out trying to get VMWare Server 2.0 on XP-64 to produce decent PpD on this i7 box. WinAFC, and other affinity tools, was having a really hard time managing affinity properly and managing priority was a pain in the ass. I suspect this is because of the four HT cores and the fact that vmware server can only attach itself to two cores. After 2 days, I said screw it and went to Linux and haven't looked back. :D Hopefully you'll have better luck.
 
Not much luck. VMWare server isn't playing nice at all. I can only dedicate 2 cores so I'm not going to mess with it much more right now. As this is my gaming box, I need to keep Windows on it...
 
Just run more than one virtual machine in VMWare. That'll let you get around the 2-core limit.
