I just installed F@H on my Halflife Server, Abit BP6 w/2x Celeron 466, will it use both chips or just one?

You have to run 2 instances of F@H on your comp in order to take advantage of the dual-cpu's.

The console is best for this. Extract the console files to your hard drive, then copy all the contents to a second separate folder. In the second folder, edit your client.cfg file and change the MachineID to equal 2.

Put a shortcut in your startup folder to each exe and let 'er rip...

So, what about Intel CPUs with HT? Can these CPUs run two instances of F@H and get a small increase in output?

That's the only time you see an increase in output. I've seen figures that show a 15-30% increase if you hyperfold. A non-HT machine will not give you an increase in output.

Ummm... so do I need to just run another instance of the console or create an entirely new install in a different directory to do this correctly?

just copy the FAH directory to a new folder, change the cfg file to say machineid=2 and run the .exe from there. You'll have 2 exe's running then, one outta each folder.

Whenever I try to do that and start up the new console it resets the machine ID to 1 and wipes out my other data in the config file such as the user name and team number. Any ideas?

That's weird...it's exactly how I have my 2 machines running. I created a FAH folder off the root of C, extracted the console there. Then I created a CPU2 folder inside there, and extracted the console there too. I then changed the .cfg files to read machineid=1 and machineid=2 and saved the changes. Then I created a shortcut to the FAH.exe for each separate folder, and copied both shortcuts to my start menu. It's worked on 3 machines so far, and nothing gets overwritten.

I installed mine via the PR Folding installer. I just created a second folder and did a copy and paste into the new one. I will try to run an install for it instead.

Thanks.

k so now I got a P3 1ghz dualie running and I changed the machine ID to 2 and it wont let me fold on both CPUs. both show up in task manager. I know only one is folding because CPU usage is 50%.

running graphical client 5.03

folder 1 E:\Program Files\Folding@Home1
folder 2 E:\Program Files\Folding@Home2


Next create a shortcut to each console exe file

so you have F@H1 and F@H2 for the shortcut names

right click and goto properties on each and add -advmethods -forcesse -local -verbosity 9 to each in the target field so they look like so

F@H1 target line = "E:\Program Files\Folding@Home1\FAH4Console.exe" -advmethods -local -forcesse -verbosity 9
F@H2 target line = "E:\Program Files\Folding@Home2\FAH4Console.exe" -advmethods -local -forcesse -verbosity 9

apply and ok out of both now move those shortcuts to the startup folder so folding will start when you bootup

BAM!!!!!!!!!!!!!!!!

You have to use the CONSOLE client...

Here's how I do it:

When you download the console executable, make two folders, ie: Folding 1 and Folding 2, and make sure there is a copy of the CE within each one. Rename the CE within each folder to the same name as the folder, and create a shortcut on the desktop, named (you guessed it!) Folding 1 and Folding 2.

In WinXP, I open the Task Manager first. Then I click on Folding 1 to get it started. The first time, you go through the usual questions, such as username, machine ID, etc. Once it gets running, look in the Task Manager Processes pane, right-click on the Folding 1 line, and choose Set Affinity. I usually set Folding 1 to CPU 0, and then do the same thing for the Core that starts running for that CE. Repeat for Folding 2, setting affinity for the CE and core to CPU1.

The PITA is that if you power down, you have to do this all over again when you power back up. The good thing is, you have more control over the whole thing than with the Graphical Client.

I can post some step-by-step screenies if you need, j-dogg...
