Dual core opteron 6128 with -bigadv

Postby iiohel » Wed Nov 24, 2010 3:12 pm

I recently put together a dual 6128 (2.0 ghz) system on an Asus KGPE-D16 with 16gb(8 * 2gb) of ram. The lowest frame times I've been able to obtain are around one hour plus or minus five minutes on native windows 7 x64. I'm wondering if there are any obvious issues I could be looking at for lowering frame times or should I just turn the system off when I'm not using it. It is currently folding project 6900.

Your times are definitely too slow for that configuration.

Which version of windows? Can you check task manager and see if all cores are running at 100%?

Can you copy/paste your FAHlog.txt file showing the beginning section where your client version and arguments are listed down to a few percentage points? Use the Code tag button above the reply window and paste it between the code tags.

As bollix said, 65 minute frame times are way too slow. 65 minute frame times will complete a 6900 WU in 4.5 days which exceeds the preferred deadline of 4 days. The point with bigadv is to return the work as quickly as possible without exceeding the preferred deadline. You would be much better off removing the -bigadv flag and running normal SMP work units. That system will do a great job on normal SMP projects.

I know that the times are too slow to complete bigadv units, but I don't think a sixteen physical core setup should be having problems with bigadv.

Windows 7 Enterprise

All cores are running at 100%

Re: Dual core opteron 6128 with -bigadv

Postby bollix47 » Wed Nov 24, 2010 5:05 pm

Is there a setting in the bios call something like "Cool n quiet" that needs to be disabled? Can you check your processor speed when running FAH? Has it backed off to something like 1.6?

Sorry that I can't be more helpful but I'm not too familiar with AMD.

I just searched for information on the 6128 and was not able to find the information I'm looking for. AMD has been planning on combining a single FPU with two integer cores with multiple pipelines. Does that apply to the 6128? The fundamental question is not so much how many integer cores you have but how many FPUs you have.

I have a pretty good understanding of Intel's i7 which has 8 integer cores and only 4 FPUs. Although it meets the minimum of eight cores required for bigadv, it has to run above about 2.2 GHz to meet the earlier deadlines -- and I don't know how they are doing with p6900. The intel i5 has only 4 integer cores but pretty much the same floating point performance, clock for clock.

Recent reviews for both AMD and Intel often seem to focus on applications like encoding or server apps where the integer cores and/or high memory bandwidth are important without considering applications like FahCore_a3 that needs massive amounts of floating point work.

It's not clear to me where your system fits into all of that or the specific characteristics of Project 6900 but I'm sure somebody will fill in some of that information.

What does CPUZ say your cpu speed is?

And as bollix 47 said, make sure Power Now is disabled in the BIOS.

My understanding is that current opterons are just fused istanbul/shanghai cores packaged in the new sockets, thus an 8core 6128 is actually a pair of 2.0ghz shanghai's on one chip. The closest AMD system i could find in the A3 frame times thread was an quad socket 8356 setup giving 16 cores over 4 chips. PPD on that is about 29k so i reckon you should be seeing about 25-27k PPD with your setup.

I agree with the others, run CPU-z and feedback what clockspeed it is showing, it sounds to me like your system is downclocking.

I am running my first P6900 right now. I am getting TPF of around 39 minutes on my i-860 (4 physical + HT seen as 8 by a3 core). Overclock is 3.6GHz with turbo still enabled. With 16 cores at 2GHz I would think you would be beating my 8 at 3.6GHz. Maybe it does have to do with FPU's but that is over my head.

It appears faulty ram may be the problem. The system is currently down. When I get it running again I'll report new results.

Actually, that's pretty decent for a bunch of 2.0 GHz cores I suppose but not all that much faster (~10K PPD) than my i7-920 @ 3.8 GHz on a 2684.

Which my 2p with 3.1GHz Shanghais being just about as fast when it was running -bigadv.

Hey iiohel,

I have the same motherboard currently with two 6168s, and I found a few things to help with your folding performance once you get your RAM problem resolved. You should be minimally at BIOS revision 0606 for these to take effect and not affect stability:

In the BIOS do the following:

1) Make sure in the memory configuration that "node interleaving" is enabled. It disables NUMA BIOS support and tends to show a very large improvement in folding performance in the order of 25 to 30%
2) Make sure your maximum P-State is set to 0 (zero)
3) Disable Cool 'n' Quiet
4) Disable "PowerNow"

Another folding user for EVGA has an identical configuration and is seeing 35 minute times-per-frame on 2685 units, so the 6900 units should run a tiny bit faster than that on your setup.

If you need any more info (as I can take BIOS screenshots from the built-in IPM) PM me or just post here.

Good luck!
