MultiGPU folding problem

[Denithor]

Have two GPU clients running on the folding rig in my sig.

The first client works perfectly, turns in WU, downloads another, keeps on cranking.

The second, however, finishes a WU, turns it in, then just seems to start folding the same WU over again (it shows it working, progress being made, but no points are accumulated and Fahmon shows zero ppd after the initial WU is turned in. If I manually stop & restart the client it will download a new WU & crunch through it, but then the cycle starts again.

Any suggestions?

Sounds like they are using the same client or macine id. Stop the second. Delete client.cfg, queue.dat, work folder, unitinfo.*. Tehn run again and config, and make sure that you specify "advanced options='y', and make sure you select a machineid that number one gpu is not using (it in the top of the log, right after you start it, somewhere on fahlog.txt) Default is 2, so it number one is machineid=2, then select 3 for the second folder gpu. Then restart.

I have 7 boxes configured this way, and it seems to work for me.

Thanks, I'll give that a try this afternoon when I get home. You can have the same machine ID as long as they are on different machines, correct? IE - machineid=2 & machineid=3 on first rig and machineid=2 on second rig (look at my sig for why).

 

[Markfw]

right, you can have up to 16 machine id's on the same physical server.

Yup, each "client" has a unique ID. It is made up of "MachineID" plus "UserID". The UserID is downloaded from Stanford and stored in the Registry, it is different for each computer.

Everything else done & it's working again, I will keep an eye on it to see if it restarts correctly. However, where do I set the advanced options=y ? I don't see that anywhere.

I think they mean as you are answering the configuration questions, one of them will ask you if you want to modify the advanced options. When you answer Y, it will ask some more questions.

Note where I answered yes to change advanced options, then I selected 3
when asked for the machineid, since this is for the second card in the box.

Aside from username , you should answer all the questions the same as I did for your second client, and make sure you use " -gpu 1 -forcgpu nvidia_g80" at the end of your shortcut. Mine looks like the below:

C:\folding_gpu2\Folding@home-Win32-GPU.exe -gpu 1 -forcegpu nvidia_g80

Bringing this back up because it started happening again a week ago.

Since then, I've gone back through deleting the WU & stuff again. It works once and then stops again.

I've also completely uninstalled the GPU clients and reinstalled from scratch the latest copy from the download site. Again, this works for a couple of cycles but then GPU2 just stops with a completed WU and sits there (doesn't turn in, doesn't download another and obviously doesn't start crunching again).

Note I'm using the graphical interface version, not the console client, does that make any difference?

I'm not using the -forcegpu line on mine, and it should be G92 for my 8800GS/9600GSO/8800GTS right? Do you think that could make a difference?

 

[Markfw]

First, I recommend the console version. Second, I can;t even get my second client to even start without the -forcegpu nvidia_g80, use it for sure as well as the -gpu 1 flag.

 

[Denithor]

Should the line be -forcegpu nvidia_g80 or -forcegpu nvidia_g92 for use with G92-based cards?

 

[Markfw]

there is no 92 hint. The g80 works fine on g92 cards

 

[Denithor]

Well, I think I've gotten it working now.

Installed the console version, set it up exactly as you specified and both are running.

One question - are the two DOS/command prompt boxes going to sit on my tray whenever the clients are running?
