IFF you are wondering how others have applied clusters, other than the one's I've mentioned earlier, look here for ways to use yours!
Hope this helps

This is my code to enable nfs,
192.168.2.130 is server
192.168.2.118 is client

http://murga-linux.com/puppy/viewtopic.php?t=45090

we only need to install nfs_common.tar.gz from above site, in the end both server and client will be able to access /mnt/my.

(already included at the 1st post)

####NFS ---need nfs_common.tar.gz only
### change drive="sda1" to your mounted device
## please create ~/my-applications/clusterdata/ip-list which contain list of ip
#need passwordless ssh

drive="sda1"
mm=`head -n 1 ~/my-applications/clusterdata/ip-list`
m=`echo ${mm/ /}`
echo "M="$m

rm /etc/exports
echo "/mnt/$drive *(rw,no_root_squash,no_subtree_check,sync)" >>/etc/exports
modprobe nfsd
/etc/rc.d/rc.nfsd start
x="mount-FULL -t nfs $m:/mnt/$drive /mnt/my "
echo "x="$x
for i in `cut --delimiter=: -f1 ~/my-applications/clusterdata/ip-list`;do ssh $i "mkdir /mnt/my"; ssh $i "modprobe nfs";ssh $i "/etc/rc.d/rc.portmap start";ssh $i $x;done
####NFS

Any suggestion beside buying a new harddrive is welcomed.

@Master _Wrong has done all of us a very valuable service. I am showing this picture here because over the past couple months, many who come here have an inaccurate perception of a cluster.

[img]http://docs.google.com/drawings/edit?id=16jMd2gmt5YmmOlLWmb1q7fhufv4m0qKoKCZQJ348J54&hl=en[/img]

This picture is worth a thousand words, as, it shows where to place the monitor, keyboard, and mouse for the cluster. In a true cluster, the nodes/workers/slave PCs DO NOT HAVE A MONITOR, KEYBOARD, OR MOUSE. But they all work together on behalf of the workload within the cluster.

Hope this helps
