An article by Daniel Oberhaus in which he offers a quick inside how Wei Lin built a scalable computing cluster comprised of $7 chips. Github user Wei Lin has demonstrated, it’s possible to make a home made computing cluster that doesn’t break the bank.

In most cases, a supercomputer is actually a computing cluster that is comprised of hundreds or thousands of individual computers that are all linked together and controlled by software.

In his solution Lin used ESP32 chips. A single Raspberry Pi costs around $30, an ESP32 only costs about $7 (manufactured in China).

The main challenge, according to Lin, was figuring out how to coordinate computing tasks across each of the chips. For this, they used a program called Celery that is optimized for synchronizing computing tasks across several cores.
