I setup a dual socket asus mobo and 2x E5-2650s yesterday. Running Win 7/64 with a VM VirtualBox and Ubuntu 11.4
Now have it set for 32 cores with 8972mb of ram. First thing is it does not run at 100% on both chips one chip runs fluctuating between 75 and 90% the other never goes above 75% usage. I pulled a 6904 and it is taking over 55 mins per frame.
Is something wrong here, I thought this setup would kick butt.

I'm sure it will in native Linux running the kraken. It might still work to run the kraken in a VM, though it's difficult for me to see how an affinity locker can work inside a VM. Other possibilities involve the dynamic load balancer not starting. One of the tricks of the 4P crowd is to cause the dynamic load balancer to start. I think that's built into the latest kraken. Still another possibility is the fah configuration calling for -smp 24. Just for jollies, I would configure the client with -smp 32, rather than let the client decide as it would with just -smp.

I will give the -smp32 a try.

Ok -smp 32 did not change anything. Is their a guide for doing the setup the 4P guys are running.

I haven't kept up with that. Check our 4p sticky and if you don't find it there, try [H]. All that is going to be native Linux tips and instructions, since rather expensive Windows is required to run more than 2P and it's senseless to run dedicated folding rigs in Windows and use a VM to get the Linux only BA WUs. Some of the productivity tips, like I mentioned above, may not work in a VM. I assume there is a reason this machine must run windows.

No Sir, as long as I have Firefox and can print to a network printer I am willing to give Native a go.
Will need lots of help I am sure.

Well if you got Linux going in a VM, you can get it going native. The trick is configuring the HD to use the ext3 File system, which requires a custom installation. I found this quide: http://www.linuxbsdos.com/2011/05/04...-ubuntu-11-04/

It's vital to use ext3 to avoid an hour delay in the closure of the WU.

Just so I understand. This guide is to install Ubuntu 11.04? I start by putting my 11.04 iso on a dvd?? This install will be on a 120g SSD does that matter?

First thing to do is to turn off the power cutting options in the BIOS, and check that you have the RAM set up as the board manufacturer recommends for interleaving the memory. Supermicro owners manual showed how 4GB of ram could cripple a multi-cpu system much more than you'd expect.

The guide I followed was the 2 and 4P guide on [H]ardOCP:

Sorry but this is my first server mobo and bios. It is very confusing compared to a standard asus mobo. I see many problems right from the start. Like this= nd check that you have the RAM set up as the board manufacturer recommends for interleaving the memory. Supermicro owners manual showed how 4GB of ram could cripple a multi-cpu system much more than you'd expect.
Have no idea what all that means. Please remember you are talking to a guy that took 2 days to figure out the VirtualBox install and needed step by step to get it done.

RAM is organized by "Banks" (sometimes called "channels"). You want to be sure each bank that has memory in it, is full - nothing part full and part empty.

That allows much quicker memory access times for your system.

I'm pretty noobish myself when it comes to Linux.

[Hardass]

Before I start, can I use driver disc for mobo with Linux or do I need to download special drivers??

[TheNewbie]

I used musky's Ubuntu guide for my sr2 installing BFS, The Kraken, Etc. very detailed and noob proof

Virtualbox scaling has historically been problematic over 24 threads, so that could be the issue.

If you can, throw native linux on there and let her rip with all 32 threads - reports say that the 2690's are good for 380k PPD on *nix with the kraken so you should be good for at least 280k - Musky's guide is excellent and will have you up and running in about an hour.

Regarding the RAM each channel will be colour coded, make sure that all RAM is in the same colour RAM sockets for both CPU's

You shouldn't need any drivers. Everything should work out of the box. Although to be sure, what motherboard do you have?

Also if you are using a nvidia or ati graphics card after you install ubuntu it'll ask you if you want to enabled the proprietary drivers, which you probably want to do.

Ram slots all same color. Going to give it a try. Thanks for reply.

You can do a standard install on a SSD. No need for ext3, so no need for a custom install. Put the CD in and boot the machine and follow the "use entire disk" instructions.

Was planning on using a Raptor 150 as test drive. But will go ahead with install on SSD.

[Hardass]

Just to clarify, no partitions on the SSD? I am following the guise on H is that right??

[Hardass]

It is asking if SSD is a GPT partition table
