Hey folks.. Just came from foldingforum.org where they recently.. some hours ago released a new core for the GPU2 Folding client version 1.07 The main new feature of this core is the support for multi gpu folding. This means that all you 3d guru's out there with more than 1 GPU in your machine will finally be able to harvest the potential power of all your GPU's *NOTE* this is not SLI support, this works without sli.. im currently folding on a 9800GTX (5700PPD) and an old 8500GT i had as a spare (770PPD) Both running the vista x64 version of the 177.41 driver. How you ask? well the original post on foldingforum.org has a few bits of info but i found it bit hard to setup myself so i'll share my knowledge. ------------------- 1. Download the new core revision from http://www.stanford.edu/~friedrim/FahCore_11.exe and replace the old FahCore_11.exe usually found in your work directory.. mine is C:\Users\Julepalme\AppData\Roaming\Folding@home-gpu ------------------- 2. This requires you to run 2 clients of the GPU2 kind, Find on your work folder, mine was C:\Users\Julepalme\AppData\Roaming\Folding@home-gpu (I'm running vista x64) Then copy this folder and make C:\Users\Julepalme\AppData\Roaming\Folding@home-gpu 2 ------------------- 3. make a 2 shortcuts on your desk with the workdir pointing to each of the folders you've just made. So you'll end up with 2 shortcuts looking something like this: Shortcut 1: Target: "C:\Program Files (x86)\Folding@home\Folding@home-gpu\Folding@home.exe" -gpu 0 -local -verbosity 9 Start In: "C:\Users\Julepalme\AppData\Roaming\Folding@home-gpu" Shortcut 2: Target: "C:\Program Files (x86)\Folding@home\Folding@home-gpu\Folding@home.exe" -gpu 1 -local -verbosity 9 Start In: "C:\Users\Julepalme\AppData\Roaming\Folding@home-gpu 2" The trick here is the -gpu argument.. telling the client to use device 0 and device 1 for the respective clients. and the start them up in seperate work dirs.. ** Remember to change the paths to the those that apply to your system ** If you have more than 2 GPU's .. say 2x9800gx2 or 3x280's(which would be 4 and 3 cores respectively) .. just make 3.. 4.. folders etc.. and change the shortcuts to say -gpu 2 and -gpu 3. Remember the gpu's start from 0. so if you have 4 GPU cores they'll be named 0 1 2 and 3.. ------------------- If everything works you'll see this in your log Launch directory: C:\Users\Julepalme\AppData\Roaming\Folding@home-gpu 2 Arguments: -gpu 1 -local -verbosity 9 ... [08:42:18] Folding@Home GPU Core - Beta [08:42:18] Version 1.07 (Mon Jun 23 10:53:13 PDT 2008) Or something similar. ** Addition In vista x64 you may need to attach a monitor to the output of each card that you want to use or it wont get recongnized by CUDA. not sure if this is still the case, haven't tested without. ** Another bug i've noticed Both of the viewers will come up stating its a 8500GT in my case.. when i got a 9800GTX as device 0 and a 8500GT as device 1, this is just a bug with the viewer i suppose.. the PPD seems appropriate for both clients. ** Updated a few not so elegant links.
