Supercomputing for Everyone featuring Ruby
summary
Hands-on report about a $150 Parallella board that combines a dual‑core ARM host and a 16‑core Epiphany coprocessor, draws about 5 watts, and sits in a 3D‑printable, stackable case used for West Point classes. Running a primes test between 0 and 16 million finds 1,030,113 primes: serial on the Parallella takes ~237s, serial on a MacBook Pro 14s, parallel on the Epiphany ~18s. Epiphany’s 12‑bit row/column bus suggests scaling to 4,096 cores is architecturally feasible.
