sudo mkdir /etc/fahclient
sudo cp config.xml /etc/fahclientMy word 'reasonable' applies to simple systems -- since Folding@home was designed to run on @home systems. They're reasonable for CPUs that support up to 8 or 12 threads with the assumption that there are 0 or 1 or 2 GPUs. For more complex systems (like yours) you may choose to modify the original setup but that initial setup should work pretty well until you have a plan of how you might want to alter it.bruce wrote:FAHClient makes some reasonable assumptions when it sets up an initial configuration, so you won't need to do much except to define your folding name and an optional passkey.
