Linux Redhat 7.2 Clustering

RSF-1 product at http://www.rsi.co.uk/ is free for 2-nodes linux cluster. This software come with installation and configuration wizard. GNU package for HA (high availability) could be found at http://www.linux-ha.com with a lot of useful documents for clustering on linux. If you care about load balancing, ipvs which is included in linux kernel is what you need. Document for ipvs could be found at http://linuxvirtualserver.org/

Hope it help and good luck

Your life could NOT get easier.  this is a free distribution based on MPI message Passing Interface.
this is what you do.
1.  download the iso image and burn it.
2. configure you main node script and put it in a floppy
3. insert cd and floppy and install the Main node automatically, with no work on your part.
4. insert cd in cpu-nodes and it would zoooon and vroooom work.
I recently build a cluster for demonstration and it took me about an hour, 25 nodes.

check out the web site and read it.
I suggest you follow instruction and build the first simple and test it, OR if you aren't new to UNIX configure your internal to use and NIS server and have a seperate
DHCP server etc etc etc.
check it out.

as I said this is step by step installations how-to.  for top of doc check
http://rocks.npaci.edu/papers/rocks-documentation/book1.html
the Rock distribution uses RedHat 7.2 V and it utilizes kickstart to its advantage.

 Red Hat has a clustering solution of there own. It will obviously be one of the easiest solutions to implement on
Red hat.
 It is called Pirahna; you can find comprehensive information at: http://sources.redhat.com/piranha/
 Yes, you can multicast from a Linux server;
if this is a complete answer, I can give the URL for
open source multicasting programs.
