I was given a dell precision t5400 loaded with 2 x5450's, 16gb of ram, and 2 15k sas drives controlled by a lsi 9650se-8lpml. I am using gentoo that was compiled to use bfs. (non genkernel). I am using the -smp and -bigadv arguments. As of now i am only able to achieve 15k ppd, i have seen lower clocked dual 771 claim to get 28k ppd and im not sure as to what i am doing wrong. At first i thought it was a mistake when i did my gentoo build, so i have tried RHEL 5 and 6 with the same 15k ppd result, and when i used win7 i got a high 14k ppd. Im not sure what it is im doing wrong, its either those that said they were getting 28k ppd were either false or like i said before, Im doing something wrong. Thanks in advance for the help guys.

What WUs? And when were those posts with those PPD numbers made?

Given the same hardware configuration, PPD in smp plummets over time, even 6-8 months. SMP is pitiful to start with relatively speaking.
 
the last few have been a 6981, 6976, 6946, and a 6975, the post that i have seen was when i googling to find out what other ppl were showing for ppd with a a dual 771 box, and someone in the overclock.net forum that had posted in june of this year stating that with dual l5420's he was pulling 28k ppd in smp
 
2xL5420 with Linux running through a vm on windows I'm getting 15250-17750 ppd. The low number for 69XX units, the higher for 71XX units (all A3 core)
 
I have two dual 771 machines. Both are dual L5420's, the PPD varies quite a bit. I have seen some units as high as 33k and others as low as 15k. the average is somewhere around 22k I am running ubuntu 12.04 server and the V7 client with latest version of thekraken.

How recent were those 30k+ ppd ones? Do you remember the unit numbers?

@OP, btw I'm running the 6.34 client.
 
tobit?

I have 2x L5530 boxes that are at the 30-33k mark...

Did you install thekraken?
 
Just took a look. These are some highs from Yesterday. (copied from HFM benchmarks. These are averages for these projects but I did complete at least one work unit from each of them since yesterday)

Also project 7610 seems to give some strange numbers (as high as 104,000 ppd and as low as 2700 ppd within the last month lower numbers may be the result of power outages as I've had a few here over that time)

Wow :eek: Impressive. You do just a regular old 12.04 server install + install v7 client and thekraken? How exactly do you install thekraken with the v7 client? What directories locations do you use? What partitions/formats did you use for your install?

ext3, and you do "sudo thekraken -i" for v7 in the directory the core is in and you are good.

Code: 
/var/lib/fahclient/cores/www.stanford.edu/~pande/Linux/AMD64/

At this location you may have a FahCore_a3 or Fahcore_a4 flder you will need to go into each folder and run:

Code: 
sudo thekraken -i

i did not install thekraken.... will it give that much of a jump in ppd?
Click to expand...

Yes. Before thekraken I think this was a 20k ppd box...the 2 I got are basically twins, the mobo is diff brand/same chipset, otherwise identical down to the clients, one is v7 and the other v6.34, both on ubuntu 10.10 and ext3.

We are comparing apples and oranges here. The OP is on about Core2 arch CPU's with 4 threads each - you are on about Nehalem arch cpu's with 8 threads each - your PPD on dual L5530's is about right - not having run a pair of C2Q's i'm not sure about the 5420PPD but 28k sounds a little high

You're right but there are also some tweaks that can be done.

BTW, no need for bigadv flag on this setup, you only have 8 cores.

Oh. That explains it. What I get for not looking up that chip and assuming were related to the op's processors :p

Thanks, there are a bunch of 21k - 23k units mixed in there too.

my set-ups are near identical.
2x L5420
Supermicro X7dwe
random sata HDD
memory is a little different. one box has 4x2gb the other has 2x1gb. the performance is almost identical.

My install is Ubuntu 12.04 server (ext3 filesystem) with no added features, no gui.

I installed the V7 client and then thekraken. The instructions to install thekraken(0.7_pre15) are in the readme that comes with it. it's simply (**as root)
Code: 
thekraken -w /var/lib/fahclient/cores/
(if you didn't change the install paths then it should be the correct path)
it will ask to search through the folders or something like that. select yes and it will report the status.
 
On a semi related note, it's good to see Apollo is still folding!
 
since rebuilding my os, using ubuntu server and thekraken, i just handed in my first smp wu and i am up to 20k ppd estimated by fahmon. Thanks for the help
