Just got confirmation from the system that my PC found one:


Congratulations! Our records indicate that a computer registered by you has
found a unique prime number. This computer is running BOINC, is attached to
the PrimeGrid project, and is assigned to the Sophie Germain Prime Search. What makes
this prime unique is that it's large enough to enter the Top 5000 List in Chris Caldwell's
The Largest Known Primes Database.

Since you have auto-reporting selected, the following prime was submitted on your
behalf:

Added 94172 : 7318825406445*2^666666-1 (200701 digits)

If you have any questions or concerns, please contact me and we will surely resolve any
problem.


I'm quite pleased about that, I think this is my first prime so far.

I had one sitting in the backlog too -- and that was the first prime I've found here! Or, anywhere, actually.

So, I got the email this morning, the prime is registered and confirmed around #2300 on the top 5000 primes list, and that nice friendly "1" now shows on my account page instead of the "0" that's always been there.

Out of curiosity rather than impatience, what steps need to happen before it shows the prime on the "Prime number list for participant..." page?

Once the prime is registered and confirmed at the Prime Pages, it will show up at PrimeGrid within an hour.

I believe the first estimates were around 1 prime every 11000 tests. Once all the backlog primes are processed, we'll have some empirical data to update the estimate. :)

My account page shows two Sophie's for me but no emails yet so I guess I'm double checker :(


You *do* have some control over whether you're the initial finder or the double checker.

Want to be the initial finder? Keep your cache size low, therefore returning WUs faster. If you keep a 10 day cache of WUs, you're giving the other guy a 10 day head start!

Of course, the larger the cache, the more buffer you have against your CPU running dry if there's a problem communicating with PrimeGrid. With some projects (::cough:: SETI ::cough::) I like to keep a lot of WUs in the cache because they tend to go down unexpectedly for extended periods. Now SETI is even scheduled to be down for several days each week. PrimeGrid's actually rather reliable, as BOINC servers go, and I use a 6 hour cache here. The wingman only gets a little bit of a head start.

Of course, using a faster computer helps too, but with the short WUs like Sophie Germain, your cache size has more of an impact on the turn-around time than does the CPU speed. Even a really slow computer could return an SGS WU during the time they're sitting in my cache waiting to run.

Also, configuring your BOINC client to report WUs immediately increases your chance of being the initial finder. This is a setting in cc_config.xml.

Ooh! I never thought about that and cache sizes. I did think I was getting about double the double check credits than 1st finder. Time for an adjustment...

Also, configuring your BOINC client to report WUs immediately increases your chance of being the initial finder. This is a setting in cc_config.xml.

I didn't know this could be done. Thanks for this bit of information.

It's kind of hidden away there because for SETI, this option puts extra strain on their servers. Especially when people run with 10 day caches and 24-thread systems AND multiple GPUs. When your BOINC client connects to the server, it sends a list of every task it has, including the ones not started yet -- which the server has to compare to its list of what you're supposed to have.

Over on SETI, some people run with thousands or WUs in their queues, and each time they connect, the server has a lot of processing to do. And since they're the ones writing the BOINC software, the option to do this is hidden away where you won't find this unless you read the documentation. They don't send you the documentation with the installation, either -- you have to go look it up on the wiki.

No wonder that the Full Moon Challenge overloaded the server!
Sure, blame the power users when it is all the people who want to report asap :-)

Hopefully you can stop that option for the next big short challenge (Leonids).

Being the double checker of one sort of averages out being the initial finder of another.

Yea! I got one....well my computer did, but I'll take the credit))

Congratulations! Our records indicate that a computer registered by you has found a unique prime number. This computer is running BOINC, is attached to the PrimeGrid project, and is assigned to the Sophie Germain Prime Search. What makes this prime unique is that it's large enough to enter the Top 5000 List in Chris Caldwell's The Largest Known Primes Database.

Since you have auto-reporting selected, the following prime was submitted on your behalf:

Found my first prime @n=1290000 yesterday. :)

There's a minor mistake in the "You have found a prime number" mail:

Congratulations! Our records indicate that a computer registered by you has found a unique prime number. This computer is running BOINC, is attached to the PrimeGrid project, and is assigned to the Sophie Germain Prime Search. What makes this prime unique is that it's large enough to enter the Top 5000 List in Chris Caldwell's The Largest Known Primes Database.

Your PrimeGrid preferences indicate you wish to submit this prime manually. Therefore, please report the following prime number from the Proth Prime Search:

Congrats! That email is strangely hilarious though.

Still waiting for number 2 after almost 90k workunits but it could be worse.

edit: Nevermind! Only had 23k workunits done lol so it isn't so bad. According to the Subproject status page the ratio is about 17k WU for 1 prime found for the latest range.

Found my first prime @n=1290000 yesterday. :)

There's a minor mistake in the "You have found a prime number" mail:
Congratulations! Our records indicate that a computer registered by you has found a unique prime number. This computer is running BOINC, is attached to the PrimeGrid project, and is assigned to the Sophie Germain Prime Search. What makes this prime unique is that it's large enough to enter the Top 5000 List in Chris Caldwell's The Largest Known Primes Database.

Your PrimeGrid preferences indicate you wish to submit this prime manually. Therefore, please report the following prime number from the Proth Prime Search:

403420675947*2^1290000-1



It is a Proth Prime!

SGS is searching for a unique type of prime pair. The first step, which you have achieved is to find a prime. The second step is to find either a twin prime pair or a true SGS prime where p and 2p+1 are both prime.

It is a Proth Prime!

There are no integers k, n with 2^n > k and k*2^n+1 = 403420675947*2^1290000-1. It's a Riesel Prime found in the SGS search, but it's neither a Proth Prime, nor found in the Proth Prime Search as the mail suggests. ;)

OOPs! You are right, it is a Riesel Prime. The main point I was making for all to see was that the initial "Prime found" from SGS is not an SGS prime, and that still stands.
