I want to start folding on my desktop rig.

Its Vista with 8 cores so Im thinking I need at least 4 of these SMP clients.

What is the best practice for multiple SMP clients. I would like these to all be controlled by a service.
 
Best practice for multiple clients would be to put them in Virtual Machines running linux. I don't have any experience with that, but there is a guide I believe to help you through it.

Good luck.

Oh, btw, I believe the latest Ubuntu actually hurts folding pretty bad, so I would suggest using a different distro.

Yes, known problem with the kernel that ships with Ubuntu 8.10. Ubuntu 8.04 is fine for folding and so is the 9.04 Alpha 3 release. I can't help you with your Windows questions though, I'm a Unix guy.
 
The best way for you to go about that is to use VMWare server, and set up four virtual machines with two cores allocated to each. After that, you'll have to install a Linux distro on each (you may just be able to copy the VM four times though), and then you'll just have to set up F@H. I have two boxen running Linux right now (one's a VM on my main rig, and the other is a dedicated machine), and I'm using Fedora 10 on both due to the issues with Ubuntu 8.10 (I like to use newer stuff ;)). Ubuntu 8.04 or 9.04 Alpha would be fine though as Tobit said.

Setting up VMWare server can be pretty unintuitive, so if you get stuck on anything, don't hesitate to ask.
 
Zero82z explained very well how to setup so if you have questions, feel free since there are lots of experts like me around here ;)
 
I already use Sun Virtual Box

Do I need to go the linux route or could I use the diskless F@H?
 
The only difficult part in the whole mess is managing priority and affinity of all the VMware server sessions. You'll have to ensure that VMware sessions run as the logged in user and not as "system" and use WinAFC to manage affinity. It was too much of a PITA for me so I switched to native Linux on my Core i7. Setup the client with -smp 8, walked away, and started seeing ~9200 PpD. :D
 
On my dual E5450 box running XP64 Pro I run 4 VM's spread over 7 CPU cores.
That gives me an empty CPU core to run 3 GPU clients on.

If your running Vista then you need to run VMWare Server v2 as v1 is not signed for Vista.
Once you have it setup and the OS installed then you can use Finstall to install folding as a service.
I'm useing VMWare Server v1.04 and I've got mine so that each VM starts in the background and then starts folding without me doing anything to the box.
It works correctly around 90-95% of the time.
If one VM fails to fold then I just reboot the VM.
Once all the VM's have started I set the affinitys for them and then start the GPU clients.
I cannot start a VM if a GPU client is running as that causes an instant BSOD.

Luck ........... :D

You could use diskless as well, although I personally can't help with that since I haven't dabbled with it personally. Notfred's diskless folding setup does run on a Linux base though, so technically it is Linux.

As for VirtualBox, as far as I know based on my experiences playing around with it, it does not support 64-bit guest OSes, so you won't be able to run the LinSMP client with it. AFAIK, VMWare Server is the only free 64-bit-capable VM host software.

Correct. There was one other annoying thing about VB when I was trying to use it for folding purposes but, for the life of me, can't figure out what it was at the moment. :confused:
 
Well I wont be installing VMware server on this box, so ill have to figure something out.
