It's that time of year again for the Tour de Primes 
Here is the PG webpage for this years TDP https://www.primegrid.com/forum_thread.php?id=10427#168083
Looks like GFN16 and PPSE are large enough for the T5K the book of the 5,000 largest primes. 
They are the best bet to get a P badge for the TDK
I would think it starts at 00:01 UTC Feb.1 
Results will be available at http://www.primegrid.com/challenge/tdp_2024.php.
 
From the PG thread:
For the month of February, an informal competition is offered. There are no challenge points to be gained... just a simple rare jersey at the end of the month to add to your badge list. No pressure or stress other than what you put on yourself. :)

For 2024, we're bringing back the badges introduced in 2018:


 

•  Red Jersey -- discoverer of largest prime
•  Yellow Jersey -- prime count leader (tiebreaker will be prime score)
•  Green Jersey -- points (prime score) leader
•  Polk-a-dot Jersey -- on the 29^th of February we'll have a "Mountain Stage" and award the Polk-a-dot Jersey to the one who finds the most primes on that day (tiebreaker will be prime score for that day). Yes, it's a leap year, so the Mountain Stage will be on the 29^th.
•  Prime badge -- awarded to everyone who finds an eligible prime during the month of February. This is a counter badge, so if you find more than one prime it will show how many you've found, up to 99.
•  Mega prime badge -- awarded to everyone who finds a mega prime during February. This is a counter badge.
•  Mountain Stage prime badge -- awarded to everyone who finds an eligible prime during the Mountain Stage. This is a counter badge.
•  Mountain Stage mega prime badge -- awarded to everyone who finds a mega prime during the Mountain Stage. This is a counter badge.

Does this give best results with CPUs or GPUs?
 
Which type (features) of CPUs work Best?

CPUs with AVX512 like X299. I9-7900x and so on
Then AVX2 then AVX. But AVX512 really does well.
That’s for LLR2 tasks like PPS and PPSE
GPU are best for the GFN primes like GFN16 through GFN22
But finding a GFN prime over 18 is rare
GFN16 and 17 are common
PPS and PPSE are your best bet with a CPU
PPS are mega primes. Primes with a million digits or more. So are GFN17 and larger

Thanks bill

If I am not mistaken every sub-project is a mega prime except PPSE and GFN16.  I am pretty sure that's correct.
GFN18 are not common nor are they rare. They come along once in a while. Sometimes a few will hit, then a drought.
They are pretty large, nearly 2 million digits. 
Mountain stage day is about finding as many primes in that one day, so PPSE and GFN16 are the best bets. 

Congrats on the prime bill1024. The teams first in the TDP.

Congratulations guys. Ok yodap, it's your turn now!

I missed that NerdGZ found one yesterday also. Congrats!
Now it really is my turn. 

Congrats guys! I expect things to go like they normally do for me and find zero primes. If I get lucky I will find one and no more.
