[Beowulf] clusters of beagles

Turns out there’s a wealth of info out there on beagle board (and Rpi) cluster building.  And it’s highly reminiscent of posts on this list 10-15 years ago.  These folks are all, to a certain extent, reinventing the wheel (and learning in the process, so it’s not necessarily a problem).
All the stuff about “here’s how to set up all the nodes, one by one, setting IP addresses, configuring ethernet interfaces”, then getting MPI up and running, etc.
It helps that there are better package managers, etc. :  you can “apt-get install”…

But nobody is doing a rocks or warewulf for beagles yet.

While I don’t think the BBG cluster would be a good computational solution it WOULD be a good, cheap, way to get a real cluster up and going with real Linux running on it and learn all about the “closer to the metal” aspects of cluster building

At $39 each, you could build an 4 node cluster for under $250.

BTW, the BB is about 1/10th the speed of a fast i7   (based on googling around and looking for timing tests of various sorts)
