I'd be really interested in seeing what it would do with Linux NOT in a VM.

I'm sitting tight until BullDOZER but this is great info.

Very impressive. Keep up the good folding(s)
Ok no problem when this WU is done (right now only 36%) I will install Ubuntu 10.10 and see.

Here's a link to a guide to set up SMP/BIGADV folding on Ubuntu. It's super straight forward so many will appreciate that.

[WIP] How To: Setup Ubuntu for folding use (lots of pics)

(I hope I can post that...)

The one from FAH-ADDICT.NET is of no real consequence.

People with 24 cores or less are having more success with BFS (Brain F*** scheduler) and Tear's "Affinity Wrapper" also known as Kraken that he posted on AMDZone Frontpage forums.

For AMD psychos like me with more than 24 cores, only the Kraken is showing better performance. BFS is not helping because it doesn't scale well past 24 cores (seemingly).

For Sandy Bridge, loading up Ubuntu 10.10 as per this guide is a good start, and then adding the CK patches for BFS shown here and then the kraken should be a big WIN

I just read the post. Seams doable...don't know why I didn't just figure that out for myself.....O_o Guess Linux is not quite mainsteam yet....but that is also why it is better for folding I expect. I'll give it a whirl tomorrow after my 2600K get done the unit it is on. If I post a picture of a case of beer...things are not going well...

I remember there was a new Linux folding@home VM out there but have no idea what thread it was in. Don't suppose anyone has a link to a decent one?

EDIT: Found it eventually.

I don't know where the original thread is, but Linux/Unix Documentation - LinuxForge.net is a good place to look, and you can also check EVGA's folding forums where LinuxRouter posts a lot of this stuff.

Installing the linuxrouter VM last night and PPD seems to stick right around 50,000 w/ a P2486 WU w/ my 2600k @ 4.7GHz. Around 8-10k improvement, not to shabby. I set the VM to use 2GB, which seems to be enough as the WU hasn't failed yet.
