Clustering


I am trying to understand clustering a tad better, so Iw ill tell you what I am wanting to do.

First, I will have a computer with dual-processors to act as the main interface. It will connect to the internet thru one NIC, and it will firewall that off from the other NIC which will communicate with the nodes.

1. Can I totally firwall off the nodes and their communciations if it is done on the saem PC I am accessing the internet with?

2. I want to have another PC act as the message node controller instead of my main computer, but can this be done while still letting the main make full use of clustering?

why do the 'message node controller' and the 'main computer' both need to communicate with the nodes? if you're talking about a beowulf cluster here, put the nodes on a subnet with a master node and use another nic/subnet on the master to interface the cluster. if you're talking about openmosix, put everything on the same subnet and lower he metric of your personal box so processes tend to drift away. provide world connectivity with a public pipe on a separate firewalled subnet.

Thanx! That is what I was looking for, but I was having a Dori moment.

since this is the non-linux general forum, what is up with the 'math problem' you're trying to crunch, just curious?

Actually it is for fun. I was dragged to Frys Electronics by one of my guypals when I noticed that there are adorable little cube PC's. These cubes are sooo cute! And they are not expensive. They may not have much in the area of expansion, but for cluster nodes you dont need any.

So it hit me the other day that instead of putting together a duallie, I could just assemble a small cluster and when I want to expand, just add a new node. Same effect really, for cheaper price and much more expandable.

ok, sorry i thought you mentioned something about crunching a math thing once.

>I could just assemble a small cluster ... and add a new node ... instead of putting together a duallie
are you planning to do openmosix then?

if you're serious about trying this with new hardware instead of a dual-proc MB, you might try it with older hardware first to see how it truly behaves. you're right, it is a cool way to expand but for workstation use i'd take a dual-proc board over 4 openmosix boxes with the same CPU spec just because latencies are annoying for anything other than trying to crunch jobs larger than ~5 seconds. if you always have large jobs to crunch though it saves the time of having to start them on individual machines, but i haven't found a way to make it improve things like recompiling kernels
( e.g. http://linuxquestions.org/questions/...hreadid=130900 )
or even most gimp transforms. and during these jobs, regular processes like mozilla aren't big enough to farm out either, so it all ends up sitting on one cpu. a dual-proc board would prob. balance that type of use better.

on the other hand it is nice that the ssh jobs on my fileserver migrate to my desktop when loaded but that is an old P2 yielding to a more recent processor.

>Same effect really, for cheaper price and much more expandable.
and also pretty fun to steer when it works, good luck!
