Results for 210K-220K Sierb. base 9. No prime.

Is taking riesel base 27 with k=706 with n>100K<n<1M! I'll do it this way: First sieve to 10000e9 or less on a not very dedicated machine. Then once work is only availeable to one of my dual cores I'll test those candidates remaining using either LLR or WinPFGW. This time I'll stick to my reservation, because it might keep my computer busy and it really want interfere with my initial goal of getting the base3 conjecture up to k=1e9 or k=2e9 by the end of the year :)

KEP!

Ps. Just sent on relief from hospital, as the update on the base 3 riesel conjecture attack says, so if things doesn't improve magnificantly this weekend or early next week I might not be able to bring you an update for the next week. But I guess that progress is about 10-25% for the k>2M<100M range. Thanks for your understanding!

Thanks to everyone for the testing and updates. I'll get the web pages updated tonight or on Saturday. In the mean time, an update on one of my ranges:

Sierp base 16 k=2908, 6663, and 10183 are now at n=170K; still no primes. Continuing on to n=200K.

These are proving to be quite problematic!

After he found the recently reported prime for Riesel base 31, I got an Email from Michaf on 4/30 reporting that he has now completed all remaining 9 Riesel base 31 k's up to n=68.1K.

Congrats on the nice top-5000 prime Micha! It's only our 2nd one for a non-power-of-2 base.

KEP!

Sorry, I wasn't updating the web pages while I was on my business trip. They're being updated now. Typically I will update them every 1-2 days.

Rest assured that others should notice your reservation if you post it here even if I don't have it reflected on the web pages yet. Let me know if you'd like to reserve Sierp base 12 again in the future.

Thats OK my friend, I could just have used my common sence, but I think that for now I'll stick to my Riesel base 27 reservation. ~17,000 candidates remain at the moment. I'm sieving that reservation on a not very dedicated machine, but when I reach k=100M and have them all brought to n=25,000 I'll transfer this Base 27 file and the candidates remaining to a dedicated machine.

Actually I feel like I should appoligize for making extra work to you in my state of confusion. Btw hope you had a nice business trip.

Take care!

Well I feel like (and just call me fast of change... come on someone ;)... I challenge you...) since causing so much disturbance, that I'll reserve the Sierpinski Base 12 but this time only in a smaller range of n's! So I take for base 12 sierp. n 100K to n 250K. This should be sufficient to ensure a prime found (I hope), and sieving has already begun... boy I should seriously buy myself a new Dell computer so my dual core can get some hard earned backup, anyone has any suggestions on which Intel processor to be the most efficient processor?... in case I decide (which I most likely will) to buy a second computer... and yeah yeah I know, just call me addicted but I really like to know more when I go to bed than I knew before I got out of bed :)

Take care!

You're not the only one who is addicated! This stuff is a blast!

Not a problem and I have no problem with you changing your mind on things. When many people first get started in prime searching, they frequently find out that they reserve far more than they would be interested in doing. I know I did. I'll get you reserved for base 12 up to n=250K I think the chances are still somewhat against you finding a prime up to that limit but many times it's good to bite off smaller efforts and you never really know. (Rogue reserved the final k remaining on base Riesel 13 starting from n=100K and almost immediately found a prime at n=109217 to prove the conjecture!).

The non-power-of-2 bases take a long time to test so if you have only 1-2 cores to throw at it, I think that's a good choice for a testing limit to get started with.

I'll leave it up to Anon and the more computer savvy folks to give you a suggestion on machines. I just bought parts for 6 quads at newegg.com and had a friend of mine build them for me. It's nice to have 20+ screaming cores! :-) You can build yourself a high-speed quad for under $500 if you already have an old monitor/mouse/keyboard that you could hook up to it and you know the Linux operating system. If not, Windows XP will probably cost you another $100.

Haliho,

Here is an update on my efforts. For Riesel base 19 I have reached n=25,000. There are 1605 k's remaining (attached). I've removed the k's as Gary suggested. I am continuing for a few more months, I am aiming for n=30,000
With my Riesel 25 effort I've almost reached n=10,000. When I have done so I'll post the remaining k's. At the moment there are 474 k.

Enjoy, Willem.

On Sierp base 19, I have now completed to n=10K. From n=8.6K-10K, 97 more k's were removed. 1612 k's still remain and are shown on the Sierp base 19 reservations page.

I am releasing this base. All k's are now available.
