Folding on a X2

[Dende]

I am folding for the [H] but my cpu usage only goes to 50%. Is Folding a single thread program?? and if so can I get a multithread version of folding to utilize all 100% of my cpu cycles???

I dont know much about how it works but you could always try running 2 clients
if it will let you since you have 2 cores , Not sure tho.

create another directory with the same files as the original FAH directory, and the program from both at the same time, setting each to a specific processor.

you should probably ask the dc forum about this

First, you need two directories, name one folding1 the other folding2 or something like that.

Install the console client into each directory.

Run –configonly and at the last command is machine #. Make one client #1 the other #2

Add what ever switches you are going to use such as –forceasm etc, but be sure to add
-local to each one.

Start each client and double your folding pleasure.

Above all, make sure you can run two instances of Prime95 stable for a few hours first please.

Luck

Hmmmm, why is the -local argument necessary? I run two instances on my X2 without any arguments (1 runs big WUs, 1 runs others) and it seems to function just fine. What exactly does the -local do?

I'm wondering the same thing. I've set up multiple hyperthreaded computers and even my xeon and I've never used the -local, and I've never had a problem.

Here you go guys, definition of what -local does:

-local
Use configuration files from local directory. This option has no meaning on Linux, but is vital on Windows and Macintosh for running multiple clients on a machine. It instructs the client to read its config information from the client.cfg file in the current directory rather than, on Windows, from the installation directory specified in the registry, or, on Macintosh, the Library/Folding@home directory. Information such as the user name, team name, proxy information, machine ID are maintained in the client.cfg file. The flag ensures that work does not conflict. Use "-local" only if you are planning on running more than one instance of Folding@Home on the same machine (this is only useful if you are running on a multi-processor machine). Create as many directories as there are processors on the machine, copy the exe files and client.cfg file into each of these directories, run "FAH3Console -local -config" on each and specify unique machine IDs for each directory (under the Advanced Settings option). From then onwards you may run each copy by switching to its directory and running with the -local flag.

Strictly speaking on most machines the –local switch is not supposed to be needed any longer. I have however run into a few instances where some hardware combinations seem to have fewer problems with it there.

The fact is it costs you nothing, it’s easy to type and if you need to replace a folder due to corruption it eliminates any confusion for your machine.

Call it a safety switch if you like, Stanford left it functional for a reason
