[ale] Cluster software for Raspberry Pi?

[Raj Wurttemberg]

So... The parts are ordered Raspberry Pi cluster. I'm going to start with just two nodes this month.  Now I just need to find a good cluster program. I would like for the systems to act as one distributed or parallel processing computer but I'm OK to start with a high availability cluster while I figure this stuff out.  I didn't setup our clusters at work (running VCS) so I'm reading up on Fencing and a few other tidbits. 

Cluster software I have located so far:

- Pacemaker

- HTCondor

- GreenTea Software

- grun

- mpi4py
	http://mpi4py.scipy.org/
- openMosix

- etcd

- serf

- Beowulf

This is just about to get fun. :)
