Mikus: I haven't heard of the DragonFly BSD, I'll take a look at that soon.
I came across that article about the Microwulf cluster setup at Calvin University during my initial research. I wouldn't mind mirroring their setup as well.
Milot: Thanks for the links, I've added them to my collection to review as well.
Dameon: I took a look at ClusterKnoppix after someone recommended ParallelKnoppix, if my current setup fails... I'm going to switch to using one of the *Knoppix distros.
I did not have sufficient older parts afterall... I didn't want to waste time with 200-400Mhz processors and 64mb machines... so I decided to purchase some older systems off the Net in the 866Mhz to 1.2Ghz range. Currently, I'm utilizing OSCAR (open source cluster application resources) to install the cluster. (
http://oscar.openclustergroup.org/). I'm still in the beginning phases. However, what I do not like is the fact I had to blow away my updated distro on the server node and install an older version of Fedora Core 4 because of the lack of compatibility. For this reason alone, I'm thinking about scrubbing it and using the a *Knoppix approach. I am going to allocate this weekend to try and to get the cluster with at least 4 nodes off the ground.
