> This is the largest prime number we've seen so far, with the last one, M82589933, being discovered six years prior. What makes this discovery particularly fascinating is that this is the first GIMPS discovery that used the power of data center GPUs. Mihai Preda was the first one to harness GPU muscle in 2017, says the GIMPS website, when he "wrote the GpuOwl program to test Mersenne numbers for primarilty, making his software available to all GIMPS users." When Luke joined GIMPS in 2023, they built the infrastructure needed to deploy Preda's software across several GPU servers available in the cloud.

Question to math folks (Score:2)
Is this hunt for ever larger primes just a fun math hobby or is there some mathematical, engineering, or other real world value to finding each next bigger prime?
Serious question, not my field.

Finding new Mersenne primes is unlikely to shed any light on the Riemann hypothesis.
The RH predicts some statistical properties of prime numbers, but the Mersenne primes are so sparse and so far beyond the range of other known primes that they can't be analyzed statistically.

Understanding the distribution of primes is important for cryptography and number theory.
But this is mostly just recreational mathematics.

"Massive" compared to what?
If you want to ban fun activities, there are way better places to start.
> could have been on used on something actually worthwhile.
Who gets to decide what is "worthwhile"?
Should we have a bureau of funness to decide how people can spend their own money?

One rationale that has been given is that it's a kind of "stress test" for computers and the algorithms that they run. There are algorithms for discovering Mersenne primes, and then there are different algorithms for testing primality. And if they agree, that speaks to the reliability of the computation from both a hardware and software perspective.
With respect to mathematical discovery, in some cases, there have been advancements in certain areas of math that occurred in part because of insights revealed

Prime numbers help secure cryptography. The larger the number, the more difficult to factor and therefore more secure. Especially with Quantum Computing potentially/theoretically speeding up the time to crack.

Even small Mersenne primes are of no practical use in the standard cryptographic algorithms.
And numbers this ginormous would be ridiculous to try to do routine computations with,
