1) Message boards : Number crunching : Rtx 30 series (Message 143863)
Posted 216 days ago by Profile Doc NoProject donor
So about 20% faster than a 3080 for 2x the price.
Can't say that stacks up for me unless you absolutely have to have the fastest thing available.


There is definitely a (brief) benefit to having the fastest newest card firsts. I landed a 1080ti two days early (thanks Newegg!) and part of my 3 mega prime finds was from having a faster card that could not only burn through tasks quickly, but pretty much be guaranteed to be the first to report back.

And probably lots of luck too. Luck never hurts :)

Looking at what's starting to trickle into the fastest GPU stats I'll keep an eye out for 2080 or 2080ti deals but I'm not getting a 3000 series this time. If my 970ti hadn't burned out I probably wouldn't have lept on the 1080ti at the time. I blundered into it in Newegg before everyone else noticed and still couldn't believe it even after the card showed up :)
2) Message boards : Number crunching : So Long, and Thanks for All the Fish (Message 143292)

Wow - I haven't been around much this year as other things have been under foot but I too will be sad to see Jim and Michael go. I also completely understand and I'm glad you were able to transition out before getting burned out. I've let myself burn out on projects and it's not good for anyone when that happens!

I know I'm late to the party but so long and good luck, and welcome to the new admins!
3) Message boards : General discussion : Maths whiz solves 48-year-old multiplication problem (Message 128855)

Wired Article: https://www.wired.com/story/mathematicians-discover-the-perfect-way-to-multiply/

EDIT:
And while the new algorithm is important theoretically, in practice it won’t change much, since it’s only marginally better than the algorithms already being used. “The best we can hope for is we’re three times faster,” van der Hoeven said. “It won’t be spectacular.”

I dunno - speeding up GFN 3x sounds pretty spectacular to me![/i]
4) Message boards : Number crunching : Using Fourier Transforms To Multiply Numbers (Message 124713)

Dunno if it's of any use for PrimeGrid, but I still found this fascinating and figured others would too:

Yeah and congratulations!

Here's to an uneventful migration :)
6) Message boards : General discussion : Researchers Discover a Pattern to the Seemingly Random Distribution of Prime Numbers (Message 120551)
Posted 963 days ago by Profile Doc NoProject donor
Yup, that title caught my eye: https://motherboard.vice.com/en_us/article/pa8dw8/prime-number-pattern-mimics-crystal-patterns

This at the end really got me thinking:

Additionally, the paper claims to have produced an algorithm that “enables one to predict primes with high accuracy.” While the usefulness of such a tool is not yet known, it marks another step towards conclusively solving the enigma of prime numbers.

Well, that would certainly change things around here!
7) Message boards : Number crunching : New badges for TDP (and more)! (Message 113317)

Nice - thanks for the new badges Michael! I was a little surprised to see mine. Woot!

Seriously, the servers are ordered, so that part's set in stone now.


The geek in me would love to know the details of what you guys ordered, but I understand if you don't want to open yourself up for discussion, second guessing, etc. :)
9) Message boards : Number crunching : Too many slots (Message 109292)
Posted 1365 days ago by Profile Doc NoProject donor
Something may have locked up the slots folder. There are two I can think of off the bat. First, and most likely, is a Virus Scanner. It is best to disable scanning of the BOINC folders. Second, and least likely, is the windows indexing service. During it's scan something may have changed and it went into an unknown state and could not recover.


Excellent points. And you can exclude folders from the indexing service too. I think by default the BOINC folders are excluded but it wouldn't hurt to double check.
10) Message boards : Number crunching : Windows 10 Creator Update problem warning (Message 109291)
Posted 1365 days ago by Profile Doc NoProject donor
Ouch - I have the creators update and haven't seen any issues on the two machines it's on. I think I also blocked MS from updating video drivers too - I just checked and I'm still using the NVIDIA drivers.

I found this: https://www.howtogeek.com/302595/how-to-stop-windows-10-from-automatically-updating-hardware-drivers/

I don't remember going through that but maybe I did; it's been a while.
