Please note, in case of primes from the 9th and 10th drives, please DON'T give credit to Psieve, rather use your old prover's codes listing only srsieve as the sieving software.

Psieve provides only sieving files for k<10,000. 9th and 10th drives were sieved by us using srsieve.

Thanks!

I have done some additional sieving for the 9th drive using psieve which is why I have credited it in my submissions.

Not part of any "drive", just kind of did it on my own.

Should make spot # 2209 on the Top 5000.

Kosmaj 2011-07-31 00:44

Congrats on your first prime!

You can consider adding our project, RPS (Riesel Prime Search), and the sieving software you used to your prover's account. Projects and software count separately so your own prime count is not affected. However, since you already submitted your prime the only way to do such changes is to contact prof. Caldwell, the admin of the Top-5000 site, and ask him to add new "members" to your prover's code (L2515).

Thanks!

Thank you. It's the only prime on the list with Fibonacci numbers transformed into a coefficient. {edit} Now I see it got bumped down 4 on the list overnight. Brutal!

I tried adding NewPGen but there was no option for it. I don't know enough about how to do "Projects" but I thought "Projects" were things like your "drives" that go on from time to time.

Advice on how to do this in the future appreciated.

What can you do now is to mail prof. Caldwell at caldwell at utm dot edu and say "Hi, I just reported my first prime but I failed to include my sieving software and my project. Can you kindly add "NewPGen" and "RPS" to L2515".

BTW, when you created you prover's code there was a field saying "You may have worked with other persons, projects or programs that you feel deserve credit. List those are to be included using either their usernames or database ids (separated by commas)." That was the place to add "NewPGen,RPS".

Thanks!

This may be a silly question, but do you leave your computer on overnight?

SaneMur 2011-08-04 22:45

Well I decided to leave my new computer on overnight. Previously I did not since it is so loud. Still found no primes in my projects.

Does anyone know what program was used to sieve the primes in the various "drives" here? I tried to have NewPGen sieve them some more and it said something like the entries were out of order.

[QUOTE=SaneMur;268353]Does anyone know what program was used to sieve the primes in the various "drives" here? I tried to have NewPGen sieve them some more and it said something like the entries were out of order.[/QUOTE]

NewPGen will only handle one K or one N at a time and is only used now for specialist sieves where either srsieve or psieve will not work. psieve is optimised for large numbers of consecutive K's and N's and was used for the 1st and 2nd megabit drives. Note there is no point in sieving these further as they have been sieved to p=80,000T.

[QUOTE=SaneMur;268178]This may be a silly question, but do you leave your computer on overnight?[/QUOTE]

My home machine was not turned off for something like 6 years. Of course, there were a handful of power outages, but I wanted to see just how much overclocking would shorten the life of a CPU. I can report that a Celeron-566 ran at 920 for 5 yrs, 850 for 2 yrs, then fell apart and only ran at 675 or so for the last year it was in use. I believe that not heat-cycling the CPU extends its life- if you can justify the power expense, your machine will last longer by not turning it on and off.
I admit I do power mine down now if I won't be using it for 3 days, such as a weekend trip away, but it probly runs LLR 24/7 for 350 days a year.

I went a little overboard, I bought a protyped extreme machine that isn't even on the market. It has a huge heat exchanger on it and a 1 horsepower condenser. It is very, very loud. There are two different gases that mix within the chambers, and the second phase cools the gas exiting from the first phase, and the temperatures are very, very cold.
