I have been out of the best of the best, folding game for a while.. with my current machine, I am wondering what the most efficient setup would be...

Image

let's see what this thing can do!

regular SMP would probably be your best bet.

Also you could do smp with three cores and run the 4890 as well

I can't find a video card listed on that thing (whatever it is called)

Click the image, he has a Radeon HD 4890.

Take a look at this guide which will help you significantly lower your CPU usage when using folding on an ATI GPU. This will let you get a lot of use out of the 4th CPU core with the SMP client. With the Windows SMP client, its been proven better to run a separate instance for each 2 cores, but I'm not sure how adding a GPU client to the mix impacts that.

You can also consider running Linux in a VM. The Linux SMP client nets much better production than the Windows client, but the added overhead of running a VM does tax your system. On my box that's running Windows, this is how I have it configured. There's a slight (though noticeable) lag caused by the VM, but I find it worth it for the extra 35-50% PPD gain. And as always, YMMV.

I like the cross forum linking, knowledge of both teams in one spot, you're one hell of an asset, bring not only PPD but quite the knowledge as well.

Glad you're coming back tc3driver

Nah, I haven't heard from DC in ... well a long time ... uhh... what have I been up to... Well I spent the beginning of the year laid off, matter of a fact, I was laid off about this time last year... I work at a global 10 now (do yourself a favor... never work for a huge conglomerate corporation... you want to talk about waste... they got it baby)... other than that... not too much..

I don't have access to the computing power that I once had... and that's ok by me...

And how does one make holy shit? does some priest put holy water on it... if that is the case... how do you throw it? wouldn't it then burn your hands :)

so I am serious... I really need help here...

I have not been into folding since the end of the high potency beta cores for smp linux X years ago (oh so sick those were).

now they have these different SMP clients... and I am like uhhh... which one do I use... I could search.. but that would not be as fun :P besides, I have done my helping of people in the past...

Someone want to throw me a bit more detailed bone?

Thanks,
Tc

Good to hear your doing ok now. It's never fun having to search for a job, specially now days.

Post your specs and we can steer you in the right direction as to what clients to run.

There are 4 different SMP clients available to download. The first two, Mac OSX and Linux, should be pretty self explanatory as to where they fit in the picture. The second two are Windows clients, one which uses MPICH and the other Denio. Those are just two different libraries (really, just 2 different implementations of the MPI standard) that accomplish the same goal, utilizing multiple CPU cores. Under the hood, they're actually more similar than they are different.

So what's the difference and why do we need both? The Denio base client is newer and addresses multiple issues with the older MPICH client. Its more stable and more likely to "just work." However, the Denio client cannot run on 64-bit editions of Windows, so they have to keep the MPICH based client around as well since it does. These clients are both beta, so they have a set date in which they expire built into the program. At the end of the page, you'll see two replacement executables (one mpich and one denio) which are replacements that you just drop into an existing installation with a later expiration date. But you'll still have to drop these in after a new install still IIRC.

The Linux and Mac clients (which are pretty much the same) absolutely kill the Windows clients (either one) as far as PPD is concerned. It's also considerably more stable and simple to set up. These two reasons are why many (myself included) prefer the extra trouble of setting up Linux in a Virtual Machine and running the Linux SMP client there. As I said earlier, it can be a 35-50% increase in PPD. And the latest VMWare now supports 4 CPU cores, so a single VM will do.

You'll also find the GPU client which runs on any Nvidia card supporting CUDA (8000 series and later) or ATI card supporting CAL (it says HD2xxx and higher, but the older cards just can't hack it any more). You can run a copy of the GPU client along side the SMP client and really maximize your performance. However, the more complex of a setup you choose, the more of a performance hit you'll notice on your computer. As long as you have the memory to support everything you're running, it won't be a huge loss in performance, but it can be noticeable.

I did think it was a bit odd when the shrink told me that I need to get in touch with my inner monkey. Its all starting to become so much clearer now. :D
