Fedora is the next version of Redhat after 9 as redhat stopped support for desktop Operating systems. It is very easy to install and also easy to manage. Installing packages is as easy as clicking on a setup.exe file on windows. They have the rpm (redhat package manager) to take care about them and the only disadvantage was to get dependencies of the software being installed but it has tools like yum and apt-get which get packages from online resources with their dependencies and install.
Recently I came across OpenMosix project which allows us to cluster machines together. If you have a redhat machine, it is the easiest to install
1,2,3, of openmosix
Get appropriate OpenMosix and openmosix-tools packages for your kernel.
install the rpms.
edit the /etc/openmosix.map file to add all machines in the cluster.
It is that simple.
Advantages of this clustering is that when many programmes are executed on a machine, they share the cpu so for example if you have 2 programs running at the same time then each of them use appx 50% of cputime but if you have a OpenMosix cluster of 2 machines, the process automatically migrates to other computer and each of them works 100% each of each cpu's and you save time.
This is very ideal if you have lots of surplus machines then you can just add them to the cluster and login to any one of them and fire up a program then it migrates to the best resource available.
Disadvantages of this system is that you cannot share CPU you need MPI or PVM installed on top of this to share CPU and you also cannot share memory.
