This Raspberry Pi ‘Mega Cluster’ costs more than your monster PC

0

The Skynet Network YouTube channel featured an impressive Raspberry pie clustered computer, nicknamed the Mega Cluster, which cost about $ 5,000 to build.

As reported by our sister site Tom’s gear, the cluster is made up of 83 Raspberry Pi computers, each equipped with a heat sink to keep the system cool, and connected with two Netgear ProSafe switches. The vast majority are Raspberry Pi 3Bs, but a 2W Pi Zero is also included, for fun.

In the video, Skynet explains that about 25 of the Raspberry Pis are wired to the switches via Ethernet and the rest are connected wirelessly.

Originally, the cluster was intended to hold an even larger number of Raspberry Pis, but Skynet had to scale back its ambitions due to network latency issues.

Traditionally, Raspberry Pi clusters are used to create a cloud or internet server, or host a NAS system. It is even possible to group Raspberry Pis together to create a personal supercomputer. In this case, however, each Raspberry Pi is run as an individual. VPN, with a unique IP address from around the world.

Raspberry Pi shortage

Unfortunately, for anyone looking to create a similar clustered computer, the Raspberry Pis are proving hard to find at the moment, with shortages should last for a good part of next year. Some retailers (including Mouser and Digi-Key) even estimate they won’t be able to ship some SKUs until 2023.

A number of factors combined to create the shortage, including the allocation of limited chip manufacturing capacity to larger players and shipping issues caused by supply chain bottlenecks. . And earlier this year, Raspberry Pi was forced to implement its very first price hike as a result.

“We now expect our supply chain challenges to continue for much of 2022,” wrote Eben Upton, CEO of Raspberry Pi. “These challenges will primarily relate to our older products, built on 40 silicon. nm: in practice, anything that is not a Raspberry Pi 4, a Raspberry Pi 400 or a computing module 4. “

However, current stock levels suggest the Raspberry Pi 4 is just as hard to find at the moment, possibly due to an increase in pre-holiday purchases.

Skynet has promised it won’t be its last Raspberry Pi Mega Cluster, but we’ll have to wait until availability improves and prices drop for version 2.0.
