<div>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).</div>
<div>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.</div>
<div>It helps that there are better package managers, etc. : you can “apt-get install”…</div>
<div><br>
</div>
<div>But nobody is doing a rocks or warewulf for beagles yet. </div>
<div><br>
</div>
<div>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</div>
<div><br>
</div>
<div>At $39 each, you could build an 4 node cluster for under $250.</div>
<div><br>
</div>
<div>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)</div>
