According to GIMPS, this is the first time a prime number was not found by an ordinary PC, but rather a “‘cloud supercomputer’ spanning 17 countries” that utilized an Nvidia A100 GPU chip to make the initial diagnosis. The primary architect of this find is Luke Durant, who worked at Nvidia as a software engineer for 11 years

Me wondering why I haven't been able to deploy cloud instances with the A100 for an actual useful purpose for the past month

Already on the H100 bud

Babe wake up, new prime number just dropped.

To save you a click: 2^136,279,841^-1

[–] [email protected] 25 points 15 hours ago (3 children)

Formatting is off.

2^136,279,841 - 1

2 to the power of something, then subtract one to make it an odd number.

I’m using Voyager and yours doesn’t work, but the person you responded to looks fine. Weird!

I'm pretty sure that's the telephone number of a flat in Islington where I once went to a party...

[–] [email protected] 3 points 5 hours ago

Yeah...they called but I told them it wasn't you.

Hope you hit him in his two heads

What Lemmy client are you using? Looks OK on the web and Jerboa.

[–] [email protected] 4 points 12 hours ago

Using Eternity and formatting was off for me. Second reply comment was good though

Sync for Lemmy.

Here's the source of their comment.

[–] [email protected] 1 points 1 hour ago

I also use sync but the formatting and a bunch of other stuff is unfortunately pretty broken.

I don't think we will ever get a fix either ;(

[–] [email protected] 8 points 13 hours ago (1 children)

Sync still uses Reddit's markdown rules, Lemmy is a little different.

[–] [email protected] 2 points 10 hours ago (1 children)

Well this was 8 months ago.

https://lemmy.world/post/12509081

Still outstanding on Github

I assume the numbers never made business sense for them to continue development.

I guess so.
I was sorta waiting for Sync to become more fully featured before committing to an ad-free purchase, but I guess I should start looking for other clients again.

I use Jerboa out of habit because it's the first one I downloaded that more or less worked that also had the coloured bars down the side of the comments so I could keep track of what level of the comment thread Im looking at.

Heard good things about Thunder though.

Does it also have coloured usernames?

Back when I was still on Reddit I used Joey which, if a user commented more than once in a thread, their username would get the colour of the first "level" on subsequent replies. Any other username, including first comment, would be white/black (depending on night mode).

  • (red) | User1 > Comment
    • (orange) | User2 > reply
      • (yellow) | User3 > Another reply
        • (green) | (orange) User2 > another reply

I've missed that feature on all alternative Reddit, and now Lemmy, clients I've tried.

[–] [email protected] 1 points 8 hours ago

No, never seen anything like that. Best we've got is the user avatars I guess.

I don't know if this is a common feature of large primes, but the digits in the exponent (136,279,841) themselves represent a prime number.

[–] [email protected] 9 points 9 hours ago* (last edited 9 hours ago)

that does happen to be one of the defining characteristics of mersenne primes.

And searching for mersenne primes happens to be the easiest known way to find extremely large prime numbers (via the Special Number Field Sieve I believe)

this is the first time a prime number was not found by an ordinary PC, but rather a “‘cloud supercomputer’

The first time since the 90's, before that all computer assisted Mercel primes found were found by super computers.

[–] [email protected] 24 points 19 hours ago (1 children)

No first time ever. This isn’t a supercomputer, it’s a distributed cloud network that they’re referring to as a supercomputer because it has a lot of power. It’s not a supercomputer in any other sense of the word, as it’s set up on cloud providers around the globe rather than in one location in the same room.

[–] [email protected] 1 points 2 hours ago

Legit question: how is that different conceptually to the random individuals all running Prime95? Could that not also be referred to as a cloud supercomputer?

[–] [email protected] 178 points 1 day ago (10 children)

I don't know why Nvidia is mentioned at all, except the hardware. That's cool that this person found the number, but Nvidia didn't do anything except employ them once upon a time and make a product that does a thing. It's not justified to celebrate the maker of a stove when a soup kitchen feeds everyone.

This is a win for Luke and GIMPS in general, and I'm happy for them.

Almost certainly a multiple of 2 minus one
