Hello, I'm trying to build a cluster like Brian Guarraci's: http://www.theverge.com/2014/6/4/577946 ... rs-for-fun. However, when I read the specifications for the $99 board, it said that it doesn't have I/O. I wonder how to you move data to the boards without I/O in a cluster setting?
I'm very new to this and would appreciate any help.
