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

Babe wake up, new prime number just dropped.

[-] beuvons@thelemmy.club 22 points 8 hours ago

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.

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)

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

[-] mipadaitu@lemmy.world 17 points 8 hours ago

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

Hope you hit him in his two heads

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

[-] pineapplelover@lemm.ee 3 points 5 hours ago

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

[-] mipadaitu@lemmy.world 5 points 7 hours ago

Sync for Lemmy.

Here's the source of their comment.

[-] tb_@lemmy.world 6 points 6 hours ago

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

[-] Blackmist@feddit.uk 2 points 3 hours ago

Well this was 8 months ago.

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.

[-] Blackmist@feddit.uk 1 points 2 hours ago

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.

[-] tb_@lemmy.world 1 points 2 hours ago* (last edited 2 hours ago)

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.

[-] Blackmist@feddit.uk 1 points 1 hour ago

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

[-] Gingernate@programming.dev 1 points 7 hours ago

I'm also using sync

[-] LucidBoi@lemmy.dbzer0.com 1 points 6 hours ago

Using Boost and it's off for me as well.

[-] driving_crooner@lemmy.eco.br 35 points 16 hours ago

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.

[-] tyler@programming.dev 20 points 12 hours ago

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.
