In this video from the 2015 RubyConf event in Columbia, Ray Hightower presents: Parallella Supercomputing. Hightower is author of the Parallella Quick Start Guide, a great primer on this remarkable device.
“Parallella is a single-board supercomputer smaller than a deck of cards. While today’s fastest laptops contain four processor cores, Parallella has eighteen (2 ARM cores plus an Epiphany chip with 16 RISC cores). The maker of Parallella, Adapteva, is on a mission to democratize parallel computing. The company’s tag line is Supercomputing for Everyone.”
While the Parallella is not what we would consider to be a supercomputer, it is a powerful tool for learning about parallel computing.
