Found this news interesting, confirming what most of us here already realized: creating a self-hosted server out of used phones is an incredibly cost-efficient solution, especially with today’s storage and memory costs.

They’re essentially stripping out the motherboard from the phones, installing a Linux distro that doesn’t contain all the consumer device protections like a low-memory killer daemon, and finally organized together in 25-50 device clusters

Some highlights:

"The single-threaded performance of modern smartphones’ performance processor cores is on-par with or better than those of modern multicore servers "

“SPEC benchmarking results indicate that 25-50 phones equate to a modern server”

“Early experiments show that even a moderately-sized cluster of 20 phones is capable of supporting peak submission rates for a 75+ student class, with grading latencies below the default AWS backend. A 2,000 phone deployment will be capable of supporting a hundred such classes at once.”

“the deployment will also act as a testbed for smartphone-based computing at scale”
