F@H issues

[Andross182]

well thanks for all your help man. Ill try deleting the client and reinstalling it. I would really love to get 40k PPD out of the server...as my i7-860 desktop is pulling about 3k more then the server is.

No problem.

I was looking through some of the threads discussing NUMA and the memory settings might be something to take a look at....provided you can take the server off line for 5 minutes, to check the bios.

 

[Andross182]

the server has 1333mhz memory in it, however its processor limited to 1066.

Check for this setting in the bios. Enabled is what you want, if I remember right....I'll have to double check in the morning. You'll want to double check first that nothing on the server requires it, since it sounded like a production machine.

Node Interleaving
(Disabled default)
If this field is Enabled, memory interleaving is supported
if a symmetric memory configuration is installed. If
Disabled, the system supports Non-Uniform Memory
architecture (NUMA) (asymmetric) memory
configurations.

I hope that fixes my issues, as looking at other peoples box specs and their PPD make me really worry about my r410 now

I took some pictures this morning of the memory and processor settings in the bios that you can take a look at.

I'm out of ideas. This one is locked at 20, but I disabled the stuff in the bios for power savings. NUMA is disabled also, but I don't think it would make that much difference.

The server has 2 SAS drives mirrored with 8GB of RAM running SQL 2008 R2.

lol... NUMA makes a big difference... absolutely kills windows performance...

soo... on linux that would get 15-30k smp and 40-50k bigadv subtract 30% for it being windows...
so take 10k off and call it close...

10-20k smp and 30-40k bigadv

Ya know...I'm gonna go through all my servers this weekend to look for that, as I have been bit by the SMP folding bug bad....at what point should I swap over to the bigadv? Below is my badge. Been folding for about 2 days now



I need more folding power!

So make sure NUMA is disabled on all servers...got it!

I think you're good to go to switch over to bigadv, since it looks like you're getting bonus points now.

enabled node interleaving and my PPD shot up to 44k on my r410! Thanks man! Will this effect single processor servers as well?

I don't think so, according to the wiki, it's muliprocessor only.

Good to hear the r410 is working as it should.

NUMA only applies to multi-processor machines. Since F@H is not a NUMA-aware application, disabling NUMA in Windows increases performance. Apparently Linux implements NUMA better at the OS level, so changing the BIOS setting makes less difference there (and I think Linux folders leave it enabled).

Linux users should leave it disabled on 1p systems. On 2p or more systems, you want to enable NUMA and run tear's Kraken wrapper as describe in musky's ubuntu guide.
