Making use of Hyperthreading / 2 processors

[Viper007Bond]

Here we go. Let me know if I left anything out or if you have any questions by replying to this thread.

• Download the console client and save it somewhere: http://www.stanford.edu/group/pandeg...02-Console.exe
• Make two folders somewhere. I made them in C:\Program Files\ and named them Fahconsole1 and Fahconsole2. Place a copy of the EXE in each folder.
• Start -> Run -> cmd -> cd\program files\fahconsole1 (or wherever you put the EXEs) -> FAH502-Console -config (don't forget the -config tag!!!)
  
  (For these options, just pressing enter will leave the value that's in the brackets)[list:03cbac0f11]
• Set your username
• Set team number to "42134"
• Launch automatically at machine startup, installing this as a server? Type "yes"
• Leave "ask before fetching/sending work" at no
• Uh, no idea about IE settings. I guess you can leave this at default.
• Pick no proxy unless you need one
• If you have lots of RAM, pick yes for allowing large work assignments. However, I've seen my clients use over 100 MB of RAM EACH when they are working on a large assignments, so again, only do this if you have lots of RAM. The advantage of allowing this is that you'll get a lot more points in the long run.
• YES, you need to change any advanced options:[list:03cbac0f11]
• Leave the core priority at idle ("idle" is a lower priority than "low")
• Yeah, you wanna use 100% of the CPU (don't worry, since it has a "idle" priority, all other programs will get priority on CPU usage
• I have no idea what highly optomized assembly code is, so leave it on like it suggests
• If you're on a laptop, you'll probably want to pause when on battery power so that you get a much longer battery life
• 15 minutes between checkpoints will do
• Leave the deadline option at it's default
• Leave ignoring deadlines alone too
• Machine ID, the all important setting so that both clients don't work on the same work unit. Set this to 1 for this copy of the EXE and set it to 2 on the other EXE.

[/list:u:03cbac0f11][*]Close window[*]Repeat process for other EXE and don't forget to set the machine ID to a different number![*]Reboot and hit control + alt + delete. Click the "Processes" tab and then the "CPU" header twice. You should see two copies of "FahCore_XX.exe" there at the top using 40-50% of of your CPU.[/list:u:03cbac0f11]
All done!

Folding@Home forbid the use of dual processors as it screws up the workloads - but most people who can, still do

I found a guide like that pretty much right on their site (I thought)...

It's bad to use 2 threads in F@H in HT, but it's good in a REAL dual core.
