Going to use this thread to pimp and discuss my slowly growing farm.

Nodes currently running 24/7:

  • io - E6600 @ 275x9 w/ 2GB - ATI HD3870 - XP x64 (Only GPU2 client presently)
  • ganymede - Core i7 920 @ 3.4 GHz w/ 6GB - Ubuntu 6.04 Server - LinSMP v6.23Beta Client (-smp 8 -advmethods bigWUs)
  • metis - P4 @ 3.0 GHz with 1GB - BOINC (SHA-1)
 
Question on my E6600 - I am currently running normal WUs with -advmethods and -smp 2. I am near completion on the first WU, a 2669, and averaging 12m per % mark. Is this a good rate or could this config be optimized a bit better?

Sounds about right for 275x9 and a 2669 on a dual core.
 
FahInfo shows ~460 PpDpGhz for p2669 on a C2D.
So 0.275 Ghz x 9 Multi x 2 Cores x 460 PpDpGhz = ~2,250 PpD.

At 12 mins a frame the whole work-unit will take 12 x 100 / 60 = 20 hours per work-unit.
So you'll do 20 / 24 = 1.2 work-units per day.
So 1920 x 1.2 = 2,300 PpD

How close is that .......... :p

Luck ....... :D
 
Thanks guys, the E6600 is performing well and can now be left alone.

My workstation, the new Core i7, on the other hand is causing me a little grief trying to max out the PpD but I'm working on it. On the i7, I'm trying to run 1 x GPU2 and 2 x vmware with Linux SMPs. The GPU2 and one of the vmware consoles perform well. However, the 2nd vmware console initially starts off running well but ultimately CPU utilization starts to fall off and the console ends up hanging.

For some odd reason, I am unable to set affinity on the two vmware-vmx processes. I get "access denied" when I try to do this through task manager and the one affinity changer I tried didn't recognize the process. This is VMWare Server 2.0 so I'm not sure if that has something to do with it or if it is the Core i7.

I just disabled SpeedStep and tried to set some priority levels in the vmware .ini file to see if this helps the problem.
 
Ok, I think I am making some progress with performance tuning on my Core i7. I've almost broken the 10K PpD goal I am trying to reach on the two boxen combined. On the i7 boxen, I think there is a bit more that can be tweaked out as CPU usage is only @ 59%.

What ATI card do you have in that box? That GPU2 client should probably be doing a little more PPD if its a 4800 series. ;)

It's just a 3870. Nothing special. :rolleyes: Going to get two or three 4870's next month for this box. :D
 
Well that will get you over 10K PPD. :D:D

Yeah I guess that sounds about right for a 3870. Are you using HT on your i7?

Yup and it's overclocked to a modest 3.0 GHz. I'm sure I can push it harder. I'm going to try and get 3.4 to 3.5 out of it after these current WUs finish. I'm sure the PpD will come up real close to 10K PpD once I am done tweaking and find my stable sweet spot and can leave it running uninterrupted. :cool:
 
Until you get said cards you'd get a lot more ppd outta the core i7 if you run the linux client on it. I think someone posted they get about 10k ppd outta their i920 oc'd to 3.6ghz running the linux client with the -smp 8 flag.

Yeah, I really think that is what I am going to do. Was just thinking of that before you posted. I've been fighting all day with trying to balance affinity and priority levels between dual vmware consoles and not getting anywhere at all.

Will make the i7 920 the dedicated folder and put the ATI card in my E6600 and make that my windows box.
 
Ok, life is much better with the Core i7 920 dedicated to folding on Linux. I am now working on this 2669 and showing 3m frames for a PpD of 9267.49. :D Once I get my E6600 folding again on XP, I will be close to 12K PpD. :cool: Will edit first post with changes once everything is finalized.
 
Woke up this morning to find everything folding right along with no problems. ganymede is now on it's 3rd WU since installing Linux (Ubuntu 8.04 Server). OP has been edited with recent node changes. Next step is to try and get a couple more PpD by running a Windows client along side the GPU2 on io. Here's some PpD pr0n:

WOW! My Core i7 box, ganymede, just received my first really big SMP work unit. It's a 2673 worth 3840 points. I don't think I've ever seen one this big. I'm currently showing 6m frames vs. 3m frames on WUs scored at 1920 so PpD will work out the same.
 
Thanks for these numbers. I finally got the go ahead from my wife to build several boxen. It helps that my side business just loaned her business $5k for expansion purposes :)

I am VERY impressed with these numbers. The only thing that bothers me is the cost of the MoBo's and the price of DDR3 RAM.

A couple of questions for you:
- can you run an X58 MoBo with only two sticks of RAM or for that matter 1 stick (thinking 2GB DDR3-something)?
- I will be running Ubuntu 8.04
- PLEASE PLEASE when you get your GPUs in for this box, let us know if you run into difficulties getting the GPU2 client up and running. And also how running the GPU Client affects the numbers above.

I will be upgrading my main SIg Rig to core i7, but have contemplated going with core i7 instead of Q6600 for the two boxen I'm going to build. I am considering Ubuntu as it is free, but may have budget the cost of Vista or WinXP for the boxen.

Absolutely and this is one of the advantages of having the memory controller built into the CPU. Mixing and matching memory is so much more flexible and you can definitely use only 1 DIMM if you want. As you can see below, I am not using very much memory for folding so the 6GB for a dedicated folder is overkill. However, at the time of purchase, it wasn't my intention to use this for dedicated folding. :rolleyes: For a dedicated folder, I'd just grab a single 2GB stick of the cheapest, but good quality, DDR3 I could find at NewEgg and be done.

Definitely. I'm very curious as to how this will all work out. However, I do not get paid until the 3rd of the month so we are still a couple weeks away.

hehe. I'd spot you the money (just got paid on my side consulting gig), but gave $5K to wife to bolster her business and I need to buy/build a workstation for my next consulting g and that damn thing is starting to look ugly ($15K, but at least one of the servers can double as my gaming rig (SkullTrail with dual E5420's).

heh, no worries. No one has 9800GX2's in stock for a reasonable price right now anyway. I think I'm going to go with a 9800GT for my primary display controller and a pair of 9800GX2's dedicated to folding.

If that is all in the same box you might to change that 9800GT out for a 9800GTX. The GTX has the same number of shader units per GPU as the GX2 (128). Some folders have had problems with low performance when mixing GPUs with different numbers of shaders.

Well, I wasn't planning on folding with the 9800GT only the two GX2's. I'd use the 9800GT for this one game that I still play and it's perfect and cheap for that task. With the 9800GT being a single slot, I'd also be able to keep my "high performance" Intel Ethernet adapter in the last slot. I'd also be running this under Linux via WINE so it may not be an issue as well but may open a whole new can of worms. :rolleyes:

Edit: If I can't find any 9800GX2's when the cash becomes available, I will likely just go with 5 x 9800GT's. I kind of want to try this anyway. :D
