How do i know if i found a prime? Is there a mail system like on Primegrid?

Unfortunately not, if you find a TOP5000 prime, I will contact you. You can also check the FAQ what primes will be published and which not.

Riesels seem to run much longer if they suspect a prime in the 1st pass.

So it might be interesting to have a look at the task details if you catch one of those by chance.

p.s.: I guess that's not a reportable one :

1411147994*3^243348-1 may be prime, trying to compute gcd's U((N+1)/3) is coprime to N! 1411147994*3^243348-1 is prime! (116116 decimal digits, P = 9) Time : 5408.691 sec. 08:44:21 (2916): llr.exe exited; CPU time 5401.109375

I'd like to know the total quantity of primes I've found. Maybe two lists:
1. Riesel Primes
2. Sierpinski Primes

Is this possible?

Also, can you clarify the differences between the various Average task length sub-projects? Why or how are they different from each other?

Also, can you tell us if it is only the Long running tasks that are Top 5000 Prime list candidates?

I will send you a list later today. The runtime of the bases are different in range and FFT length. All 200k+ ranges from average should be listed into the TOP5000. You can also find tables at mersenne to find out the digits of all bases.

Update:
You have a PM ;)
