about
Folding@home (FAH or F@h) is a distributed computing project for simulating protein dynamics, including the process of protein folding and the movements of proteins implicated in a variety of diseases. It brings together citizen scientists who volunteer to run simulations of protein dynamics on their personal computers. Insights from this data are helping scientists to better understand biology, and providing new opportunities for developing therapeutics.

As those packages need python2 and python gtk libs and others (freeglut) , we need to install with –nodeps, ref https://foldingathome.org/support/faq/installation-guides/linux/manual-installation-advanced/
#rpm -i --nodeps fahclient-7.6.9-1.x86_64.rpm #rpm -i --nodeps fahcontrol-7.6.9-1.noarch.rpm #rpm -i --nodeps fahviewer-7.6.9-1.x86_64.rpm
after installation
# /etc/init.d/FAHClient status fahclient is running with PID 25624
dependancies
pygtk2
add python gtk for FAHControl to work
# yum install pygtk2
freeglut
add freeglut for FAHviewer
# yum install freeglut
