To start with, you need an I7 cpu overclocked to 3.5 or more or an eight core cpu to run the bigadv smp client and get bonus points;

Next, you need a 64 bit linux distro.

Here is a bit torrent download for an easy install unbuntu 9.10; 64 bit http://releases.ubuntu.com/9.10/ubuntu-9.10-alternate-amd64.iso.torrent There are about 6 steps to perform for the install, after you burn the iso to a cd.

Okay, 64 bit linux is installed. After I install it I update it, System>Administration>Update Manager. Reboot as required, then open a terminal. Application>Accessories>Terminal.

Even though the core requires a 64 bit OS, the client needs the 32 bit library so you will have to install it.
Note: With some distributions, you may need to add su or sudo to execute the command if you are not logged as root.

Open a terminal(window) and type or paste;

sudo apt-get install ia32-libs

Note: I was asked for my password before it would accept; apt-get install ia32-libs

mkdir -p ~/folding

cd ~/folding

curl -O http://www.stanford.edu/group/pandegrou ... -Linux.tgz
Note; if this doesn't work, just download to the desktop, open and copy into the "home"/"folding" folder.

tar xzf FAH6.02-Linux.tgz

Note: If you don't have curl available on your machine, use wget instead:

wget http://www.stanford.edu/group/pandegrou ... -Linux.tgz

Next you'll need the fahcore 6 . Download to the desktop and copy it into the "home"/"folding" folder.

Now select the fah6 icon, right click, select properties, select permissions, check mark the box for "make executable".
Now select the mpiexe icon, right click, select properties, select permissions, check mark the box for "make executable".

NOTE: Make sure you have your Fah passkey ready for the configuration. If you don't have it, you can get it here http://fah-web.stanford.edu/cgi-bin/getpasskey.py

Now you should have the FAH client in place and you'll have to configure it. It can be done by running the following command:

./fah6 -configonly

NOTE: During the cofiguration setup, you must select "big" in this line;
•Acceptable size of work assignment and work result packets (bigger units
may have large memory demands) -- 'small' is <5MB, 'normal' is <10MB, and
'big' is >10MB (small/normal/big) [normal]? ...choose "big"

For this line you must select "no" in order to receive the bigadv units;
•Set -advmethods flag always, requesting new advanced
scientific cores and/or work units if available (no/yes) [no]? ...choose "no"

NOTE: You must have ten / a2.core wu's submitted with your passkey before you can get the bonus points associated with the bigadv wu's

To get those 10 wu's out of the way quickly, type or paste

./fah6 -smp -forceasm -verbosity 9

When you have completed 10 wu's and sent the results you can stop the client with ctrl+c ( I waited 30 minutes and the system monitor showed nothing had stopped; even after closing the terminal it hadn't stopped; so I rebooted the system.

Now you're ready to run the bigadv wu's for the bonus points,

Open the terminal; type

cd folding

To make it a little easier for yourself, you can make a script by running the following commands:

echo "./fah6 -smp 8 -bigadv -forceasm -verbosity 9 $* &" > fah
chmod +x fah

Now you'll just have to run

./fah

Note: if you need to reconfigure, just add, (space)(dash)config after the ./fah

to start the client.

If you've just rebooted, or opened a terminal, to run the smp bigadv client; type;

cd folding

./fah

Happy folding

If I missed anything please let me know.
