Folding on Opteron 4284 "Valencia"

Post by lupin..the..3rd »

Hello all, I have a new computer, Opteron 4284 "Valencia" with 8 cores @ 3.0 Ghz and 16 GB registered ECC memory @ 1333 Mhz. My operating system is Ubuntu Linux 11.04 AMD64.

It's nicely faster than my old Opteron 1218HE but puts out a little more heat for sure.

Is there some tips for settings or optimisations for best performance on my system? I am currently running as ./fah6 -smp -bigadv and it works ok, uses all 8 cores.

Thanks you!

If you won't be doing anything else with it, booting into Runlevel 3 may help.

Edit: Apparently Ubuntu 11.04 doesn't have that option. :-(

Seems many of the -bigadv guys use a piece of software called "the kraken" to help improve throughput. I don't know anything about it, or if it helps with only 8 cores, but it's something that you can look into.

IIRC, kraken helps with multiple chips, and 16-32 core range.

If your MB will take it running tighter timing desktop memory, CL 6 or 7, will help the most in dropping TPF other then OC the cpu. 7im is right about the Kraken, it won't help on 8 threads.

What MB do you have?

And what are your TPF on -bigadv?

Actually, the kraken will benefit 8 threads on a multi-socket board. Verified on a 2P/8T system. 8-)

You are getting away with -bigadv and you only have 8 cores at 3GHz?

Not on any of the new BA16 work units, no.
