I hate Linux

Patriot could you do it by editing grub? To switch to the non "-ck" kernel if you have problems?

I just spent the last two days struggling with this beast and I don't think I could live through another reinstall :D

yes... but jebo is a linux noob... and they complicated the process for manually updating in 10.10... so anything = or > I would use a manager...
 
vmware is a PITA to get working in Linux. Go with VirtualBox, it "just installs" no complicated stuff like trying to find kernel headers that match your kernel etc... I remember getting vmware server to work, what a pain. I would not really blame Linux for that, it's more VMware making their installer really crappy.

nope. virtualbox sucks a big one too

yeh... try an ESX install if you think its linux's fault lol... I had trouble....

with your setup ;) in most cases VB is a much better solution on linux than VMWare has ever been, once your 6903 drops, you should install to 10.10, and put VB on before you install the BFS

Yes mate 24 threads, its been folding on Windows 2008 up till today, I'd tried to get it on Linux a few times in the past but got stuck with VMware issues every time.

You reckon you could install BFS after Virtualbox? Hmm

I agree that VirtualBox is 10x easier to install that VMWare Server 2 on Linux, in fact you don't really need all the whiz bang stuff of 4.x VB I just installed the 3.8 version that was offered in Synaptic, I really had got that stir-crazy trying to get it all working I just went for the easiest route in the end :0

Now struggling with why it won't move past 1% with folding after an hour. :(

CPU's at 99-100% with just thekraken. But its not moving forward even half as well as it should,
 
so without BFS your frame times have doubled?
 
Well I know they should be around 25minutes max per frame on a bigbeta and thats at 4.2Ghz, and I know what a bigadv does on this box its been running many many months on windows. So when it stays at 1% for over an hour I know something must be up.
 
yep. at 3.6ghz my SR2 gets TPF around 29-30 minutes.

That's discouraging news that BFS and virtualization appear to be mutually exclusive.
 
Well now I've got virtualisation installed I'm gonna try the new kernel
 
FYI - things I have tried:

I simply have to develop a windows within linux vm capability, but getting more than a few cores working on win7 within a vm is a nightmare...

  • VMware vsphere hypervisor will not install on SR2s - network card is not seen and fails the install.
  • Virtualbox (Win Host Linux Guest) can use 24 threads, but my 9 minute frame times turned into one hour without even 1% happening... virtualbox Linux host win guest was a failure, forget why.
  • and VMware workstation etc are core limited.
  • Proxmox is core limited to 16, and the installer wipes you whole hard drive.
  • KVM will not pass on correct topology so windows thinks each core is a socket, so limited to 2... sigh. Posted on the KVM forums with no response. There is a solution, but it is beyond my config skills right now.
  • Xen hypervisor looks possible, but is way hard to use by the looks of things... does not even have a current ISO on the website, then expect you to compile your own.

One thing I did test was Sabayon - it was pretty good out of the box with krakken = frame time 6901 of 10min10sec vs 9min48sec on Ubuntu BFS - so only 1.5% slower. This could be worth some followup to try if BFS is causing issues.
 
xen is like a car without a steering wheel.... you kinda have to lean and...
I have no desire to mess with it....
 
Thats why we are trying it the other way around.

But Sabayon sounds cool, so thats a type of Linux which might not need BFS?

OK so I tried, I installed BFS -ck kernel as per the Ubuntu Desktop setup thread, machine booted up fine but Virtualbox guests just would not start.

Used grub to boot back to the 2.6.35.28-generic (non -ck) kernel and boom Virtualbox guests kick straight in.

Everything else I am sweet with, got NUMA enabled, C-states enabled, all other settings as per the Ubuntu desktop thread. Just can't use the *F))£*(* BFS kernel.

Going to start some folding see how it performs.
 
let me know asap if you can. I'm going to be screwing with this later this afternoon.
 
So, you're getting 27 mins without BFS? What were you getting before?

Oh I see 25
 
amazingly, I just turned in two frames right around 30 minutes without BFS, which was basically the same as what it was doing with my 11.04 install + BFS.

also, for the haters:

Linux screwed up my hard drive. Irreprably. Couldn't mount, install, or anything.
Booted into windows and had it formatted within 5 minutes.

I love Windows.
 
I turned in 25 min tpf over night!? A 20% improvement without bfs?
 
Still rocking 25 min TPFs. Also getting my VMs set up.

Maybe this Linux thing and I can get along after all.
 
Whats your setup now then jebo?
Whats your OC?
Running thekraken or not?
 
Wonder why my X5650's are running so slowly @4.2 then. Mind you I think I have to dial back my OC a bit as its crapped out on the bigbeta wu it was running and then crapped out on a 6901. Wooh Linux is much more sensitive to OC than Winders. :( Hopefully if I dial it back to 4.0 it should be ok.
 
yeah the cpus aren't clocking back
But I've got this wierd message in the linux logs about pciehp card not present in slot(0) that looks like I'll have to recompile the kernel to get rid of either that or try 11.04
 
I just got done setting up 10.10 on my i7 920. So much faster TPFs! I'm averaging ~30k PPD now instead of the 23k I was getting before.
 
jebo, I'm just going for it and patching bfs and removing hotplug code from the 11.04 kernel see if that works :D

let me know if you see any benefit. I've stayed away from BFS.

With Kraken, it is not that big of a deal whether or not you use BFS. Prior to Kraken, you lost an entire core since the "completely fair scheduler" decided that it needed to be available for some reason. Still, I believe MIBW ran some numbers and still saw a little better production with 24 cores using BFS.

could be slightly better, but it's negligible. My TPF is a bit erratic anyway since I actually use this rig, but I did not notice any difference in average TPF after losing BFS

Any benefit of BFS, if any, is not worth the trade off of losing VM compatibility, that's for 100% sure.
