First, make sure you have followed the first steps (top left menu) :
Join PrimeGrid

When prompted, enter the URL:
http://www.primegrid.com/
Select which subprojects to run via the PrimeGrid Preferences.

What hardware do you plan to use ?

Just so you know, any subproject with the word (Sieve) in it will not find a prime.

It will help others find a prime by filtering out candidates so there less to work on, but won't find a prime, if thats what you want to do.

PPSE or SGS on CPU and GFN15 on GPU are quickest and most likely to find a prime quickly.

If you have a reliable and permanent Internet connection, you might want to reduce this queue of tasks. To do that, go to your BOINC Manager and reduce the "store at least xx days" values in Computing preferences. You can even reduce it to 0 if you are always connected.

The CPU is your computer 'central processing unit' or the brain of the computer. It can run cpu jobs such as ppse or sgs and others but to start off try these 1st, I've no preference it's just they don't take too long.
The GPU is your graphics card. It can also run GFN jobs and can be much faster than gfn jobs on your cpu.

It's your choice really. Just try a few and see which ones you like doing. I like GFN tasks but that's because I've have a lot of GPUS.

I found 1059094^1048576+1 on 31 October 2018, it's a gfn20, only second found so far. Over 6 million digits :) and second biggest prime found on Primegrid.

56414916^16384+1 is a GFN-14 Consecutive Prime (not very big), the other found was  56414914^16384+1 so the two are next to each other and pretty rare.

You should have a look at the following message: http://www.primegrid.com/forum_thread.php?id=7882&nowrap=true#115789. It explains how to reduce drastically the time needed to run 321 tasks.

For big and long tasks like 321, you should have only 1 task running at a time on 4 cores. Have you followed the instructions below ?
And you have a long queue of GCW sieve tasks waiting. You can simply abort them.

321 proyect
9d 20h left

If it's running on a single core it's probably normal. There are big and small tasks on Primegrid. Ppse and gfn 15 and sgs are smallest. Others like SOB can take over 2 weeks on a single core. 321 is one of the bigger ones so it's probably normal time. Some like sr5 can take 10 times the normal time if it's prime, but not 321.

From what I see here : http://www.primegrid.com/hosts_user.php?userid=1090226, you are using a AMD FX-7500 Radeon R7 CPU+GPU at 2.1 GHz. AMD CPU are not very efficient for 321 and other LLR tasks, and a clock at 2.1 Ghz is not very fast.
So 10 days for a 321 task seems realistic.

LLR, the algorithm used for finding 321 primes does not try to factorize a number, as that would be very, very long. Look at https://en.wikipedia.org/wiki/Lucas%E2%80%93Lehmer%E2%80%93Riesel_test for details.

Yes an email with Dear Prime finder, giving details of the prime. Pretty sure it's all automated. Would have to be, Primegrid has found 80000 primes and that a Lot of emails to be sending :)

I doubt anyone in the Team knows the answer to your question or they would have answered already. Try asking on the main forum under "problems and help". Someone has gotta know.

do you know how Jean program works?

would be useful for some primes that I have

http://jpenne.free.fr/index2.html

this is a LLR primlality test, and I don't know how it works

It is quite similar test to Lucas-Lehmer test. Numberphile has a nice video on it: https://www.youtube.com/watch?v=lEvXcTYqtKU (See also here: https://en.wikipedia.org/wiki/Lucas%E2%80%93Lehmer_primality_test)

To upgrade it into Lucas-Lehmer-Riesel test, some info is here https://en.wikipedia.org/wiki/Lucas%E2%80%93Lehmer%E2%80%93Riesel_test

Most likely the LLR program itself has a lot of optimizations, e.g. using FFT to multiply.

Hi,
What means this:
909*2^2685019+1 is a Factor of xGF(2685018,9,7)

It is from Robish's profile.

I know there's a better explanation somewhere as I asked the same question last year myself. I'm having difficulty finding it now. Ill post it when I find it :)

You try one any time and see if you can finish in 10 days. If not, there is not much you can do, I am afraid.
