Re: I've outed the foundation!

No wonder they called a RasPi cluster a Bramble! Brambles have thorns. It was a hint that the foundation has ulterior notions of world domination!!!

Re: Cluster (Bramble...) Design Discussion (Advanced)

<r>I've always fancied playing with clusters and had the idea of using a VM as the head/control/master.  Partly because I'd hate to waste node hardware on mere admin tasks but mostly because with so many different cluster configurations etc. a VM head brings the benefits of multiple images & sna...

Re: Parallel Pi, Combining 2 raspberry pis 2 get one more powerful computer

Connecting 2 or more RPi to make a bramble is easy [if you have more than one] - just connect all of them up via a 100Mb Network Switch -

software for clustering is a bit more complex but depending on what your doing can be as easy as a script or as complex as a OS
