I ran a few cluster tests, and all worked well (surprisingly so...), some on 5 nodes, some on 4 (one of the nodes kept giving me like 10 Mbps of...

Marking as testing complete, but I will still be messing with it here and there. A few things I haven't really focused on but would like to nail down: -...
@Zepan - Indeed, the problem is USB-C is only one of two supported power supply options for this board, and I wanted a way to compare both — and also...
FYI I will be testing the LM3H separately in my SBC Reviews repo: https://github.com/geerlingguy/sbc-reviews/issues/79
@caiodelgadonew thanks for posting your results! Interesting on the power measurement, but if you just need nodes and don't need speed, that could be a useful setup.
@garanews - That's awesome! I imagine tweaking things a bit, you might be able to hit 200+ Gflops. Though not sure how much RAM you have per node... that is...
@garanews I typically tweak things a bit, especially for systems with big.LITTLE cores, since the memory management between cores can be dodgy and lead to big slowdowns. Maybe also try...
Not bad, in terms of case design. It looks like a little retro speaker or something :D
@normanr - Ah, so that may be why I didn't see it in the 6.6.y fork.
