Title: An Octa-Pi?
Post by Fernando on Aug 10^th, 2017, 8:13pm

Building a network cluster with PC is not so easy. Back when I was with the school system, I clustered their G3/G4 Mac Labs to make a super cluster of 64+ nodes. Despite the number of nodes, it was not fast because school network was slow itself. Internally within the lab itself, is was a T100, but when it goes out, it connected to a T10 network. So one can imagine how slow that was.

Clustering Pies have bee around for a while, but in this case they hit the same bottle neck - they used the R-Pi 3's wireless as the clustering agent, which is around 56Mbit (about 1/2 of wired T100). Thus they limit this project to 8 R-Pi 3's, calling it OctaPi.

But one can use wired network for faster results and adding more nodes. One just need a T100 8port or larger hub. You just need to edit a few lines in the config to switch it from wireless to wired networking. If you have less Pies, you can use 6 R-Pies for a HexaPi or 4 R-Pies for a TetraPi.

Somebody already used an OctaPi to create and break Cryptography encryption.

Thing is, other systems use the same principles to build such clusters, and with Orange Pi and Banana Pi using Giga-bit wired networking (T1000), such clusters using their systems would be much much faster.

Here are some links for the Orange Pi, though one is for Armbian so that opens it for any system with Armbian.

there are a couple Russian links on this one, so click with caution.

Here some for Banana Pi Clusters:

http://banoffeepiserver.com/banana-pi-server-cluster/
from same site: http://banoffeepiserver.com/banana-pi-server-cluster/building-the-cluster.html

Same guy from last link; but on Lemaker's forum. Lemaker used to make the B-Pi with China before they broke up into 2 separate companies making the same thing... They are supposed to have better tech support...
http://forum.lemaker.org/thread-1982-1-1.html

Banana Pi's (China's website) on clustering B-Pies (minimal info though): http://forum.banana-pi.org/t/banana-pi-bpi-m3-pi-cluster-project/889

German Website (in English), using B-Pis and Legos - LMAO!!! http://www.owncluster.de/

and a little something for the Nano Pi...
A 40 core cluster using 5 NanoPC-T3's - their OctaCore Nano!!
