It was necessary for me to evaluate G4 architectures for embedded distributed applications about three years ago. The first system available was a PowerMac G4 (350MHz). We put YellowDog Linux on it and then set up the small Beowulf cluster (master and four rack slaves). The installation of YDL was probably the most time consuming (me as a newbie). SSH was my most difficult topic.
I found the NFS pretty simple to administer and the launch of MPI applications from the shell easy using all the open source MPICH with CH_P4 (TCP/IP). If I wanted to review all the MPICH docs and Linux docs I'm sure it would be many hundreds of pages.
I have always liked the Mac hardware and simple to use software. The software described seems very easy to use and administer and I applaud the developers. However, the post seems a bit biased towards the developer and the one page HOWTO.
However this tool only works under MacOS. My clusters are portable to Linux, Solaris, VxWorks OS using Pentium, PowerPC, Sparc, etc. Portability is a distinct advantage when going from workstations to embedded deployment. I am also unsure if the entire MPI v1.2 standard functions are available on the MacOS platform.
