Welcome to the Centos Folding@Home team!

On behalf of the Centos Folding@Home team members we thank you for your interest in us and our progress. If you would like to learn more about what we do, please follow this link to the Folding@Home homepage. New to distributed computing?, its not a problem. Folding@home is being done for medical research, and here is the simplest description of distributed computing: Many computers working on separate pieces of the same puzzle are faster than a few computers working on many pieces of the puzzle. By "distributing" the work load to as many computers as possible, results are faster and accumulate faster. This provides more information to the people who can use it, thus letting them actually work with the results instead of working to get results. Hopefully the above summary doesn't leave you lost and confused. If you are still with us then great, but if you're feeling lost? You can search google for distributed computing for more in depth information.

Now on to Centos folders and Folding@Home. We are a team of members with various computer setups and knowledge. Our primary operating system of choice is Centos and our favourite distributed computing program is Folding@Home. You can see our team stats by clicking here, this should be updated fairly regularly. Would you like to join the team? Well, if so it is as simple as visiting the Folding@Home website and downloading the version you prefer. Once you've got it you might find it useful to read this FAQ written by Jtang613. Please note, our team number is 48721. There now, its just as easy as that and now you are a part of the team. Welcome to the Fold! :) Further information about various installers and monitors can be found here. My personal preference is to use finstall to install and a superkaramba theme to help monitor the work unit.

I've now configured my folding setup such that its now started as a daemon before I even get to the desktop. I did this by including the following lines into the /etc/rc.d file

echo "Starting folding daemon..."
sudo -u blockhead sh -c "cd ~blockhead/foldingathome; ./go"

Obviously you will have to enter the path to your folding folder and it is assuming that you've configured sudo to work for you. The file "./go" has these lines in it
#!/bin/bash
cd /home/blockhead/foldingathome/CPU1
./FAH502-Linux.exe -forceasm >>folding.log 2>&1 &

And I'm assuming that your user name is not blockhead so you might want to change that too :)

Munin and Folding@home.

I've recently installed munin and whilst browsing its plugins I found one labelled 'foldingathome'. I then started investigating how I could get it to run to give me a graphical output. You need to edit '/etc/munin/plugin-conf.d/munin-node' to have a line as follows;-<
[foldingathome]
user blockhead

Obviously you use your own users name, and then, as sudo or root, run '/etc/init.d/munin-node' which restarts the node on your setup.

It then appears on the munin overview page under the sub-heading of 'Other'.
