Help, quad CPU on linux 32 bit runs only one

I am stumped. I have three computers running f@h, a single CPU one, a dual Intel one, and a quad core AMD. All run Debian 32 bit.

The single and the dual work perfectly, running the right number of processes FahCore_82.exe at 99% max and doing the right thing.

But on my quad, I can only get one CPU to run. If I run four copies of fah6, I see four processes, each at 24%.

I know that the standard linux client only runs automatically on 64 bit linux, but I'm not changing. So I need help.

I've run finstall, and have four subdirectories, named CPU1, CPU2, CPU3, and CPU4. Each has an identical client.cfg file, except that the
machineid=2
varies properly from 1 to 4


The quad actually has a nice ATI Radeon HD 2400XT which I'd like to get to work as its a headless server, and the video is totally unused. But I can't see anything about GPU without Windoze, and I'm not willing to think about that.

Thanks

Not a linux person but it sounds like you have the std client, you should run the SMP client on the dual core and quad machine to fully utilise the CPU cores when it is not otherwise busy. In fact on the quad core you can probably run 2 x SMP clients (but I do not know how to configure it on linux).

If you do have or do try the SMP client, remember to have the -smp flag set to run in SMP mode.

There is no GPU client for linux or OS/X just yet only Windows.

from the Stanford site:

SMP works on 64-bit linux only

so the only option with 32-bit linux is running 4 single core clients with the machineID different (as I believe you have it setup now)

really I would look into finding ways to upgrade your existing installation to 64bit as most newer linux programs are being natively coded for 64-bit and then "emulated" to be run as 32bit...

Nope, SMP autodetection only works with 64 bit Linux, not 32 bit. and I'm not willing to reinstall. At least that is what the Stanford forums say, but it works perfectly on my dual core 32 bit machine, so something is not right

So, given that there is no support automatically, how do I do it manually?

There are rumours of wine allowing GPU support, but no details

No, I really don't want to do that. I don't want to do that in general, and sure don't want to do it for a charity thing. I'm willing to do folding on a powerful computer if it doesn't mess my life much. But there is no way I'm reinstalling and reconfiguring my machine, I run 6 websites, process tons of email, have thousands of users, etc.

If I wanted a 64 bit machine, I would have bought one, and would have bought more than 3 GB of ram.

It ain't broke, and I'm not about to fix it.

I've received this 'advice' before, and the arrogance of it amazes me.

It looks like you are doing what you can for now.

The new versions are not quick to come forward. So I think the GPU version is some way off as they are talking about finishing the viewere update on the current client first.

I am also hanging out for that GPU as it will be when they might do the OS/X one as well.

you did not mention the server usage before, otherwise I would not have suggested what I did. All we have to go by is the info you give us.
As it is, all you can do is use 4 separate clients, one per core.

And how do I do that? If I start the four copies of fah6, they share one CPU.

Beyond my area ok knowledge, I have posted a request in the dev hardware forum where the guys hang out to see if someone can help.

I thought this was the dev hardware forum for F@H. What am I missing?

I think (guess?) the finstall script didn't recognize my quad as four processors, but its very hard to tell what its doing.

it is very easy...
as you set it up, say yes to advanced options... and set the first to MachineID 1
set the second to MachineID 2 and so on...
ID1 will use CPU0 (the first core)
ID2 will use CPU1 (the second core) and so on

I've done that and it doesn't work.
All instances of ./FahCore_82.exe run on a single CPU.

All of the client.cfg files are identical except that they have different values of machineid=1
machineid=2, etc.

I have no idea if its case sensitive.

I just re-ran finstall. What exactly do you mean here?
When I ran finstall, and said yes to advanced, it asked:

Machine ID (1-16) [1]?

but it only did it once. It did not ask for each CPU.

finstall writes out:

Setting up FAH client(s) for 1 processor(s).

Directory /home/pfarrell/foldingathome is present

Fixed it. I was running
Debian GNU/Linux, kernel 2.6.18-6-486

I installed the 686-SMP kernel and now its working properly.
