Bases 2 & 4 reservations/statuses/primes

[Jean Penné]

I am now sieving the 16 remaining k's for Riesel base 2 odd n's (in conjonction with Riesel base 4) from n = 256K to 2048K base 2, using srsieve, and shall distribute the sieve files in Newpgen format when sieved enough(at least p = 100 billions)...

For now, I wish to reserve again k = 155877 (in conjonction with k = 311754 for base 4) for LLR testing up to n = 512K (524288) base 2, or, I hope, prime found below...

Regards,
Jean

Great! The sieve files help a lot. Perhaps we'll can make a mini-drive out of it.

Do you know that I tested Riesel base 2 odd-n k=6927 to n=600K base 2? That was done in conjuction with Riesel base 4 k=13854 to n=300K base 4. But if you want to include the range as a double-check in your sieved file(s), that works for me.

Yes, I know that, and it is great! We may use the corresponding sieved file for double-checking, or starting after your upper limit...

I wish to reserve k = 39687 (in conjonction with k = 79374 for base 4) for LLR testing up to n = 512K (524288) base 2, or, I hope, prime found below...

P.S. My sieving is progressing fine...

[Jean Penné]

To-day :

k = 39687 is tested up to n = 416853, no prime.

k = 155877 is tested up to n = 400351, no prime.

The 16 files (for n = 256K to 2048K) are now sieved to 235 billions ;

I am abroad for a week and shall send them when going back.

Sierp base 2 odd-n all remaining 7 k's now at n=365K, 2 of which are being double-checked.

Nothing to report.

[gd_barnes]

Sierp base 2 odd-n all remaining 7 k's now at n=414K, 2 of which are being double-checked.

Nothing to report.

Hello,

To-day :

k = 39687 is tested up to n = 494637, no prime, continuing up to 512K.

k = 155877 is tested up to n = 527237, no prime, so, I am unreserving this k.
I wish to reserve k = 133977 in place.

The 16 files (for n = 256K to 2048K) are now sieved to 569.7 billions ;
They are available for downloading from my personal site, at URL :

http://jpenne.free.fr/ConjRus/

I am continuing the sieving and shall update these files on place when 1 Tera reached.

Regards,
Jean

To-day :

k = 39687 is tested up to n = 535677, no pime, so I am releasing this k.
(The machine I used for it beeing not perfectly reliable, I think this k needs a double-check in range 256K to 512K)
I quoted my previous message to make a reminder about it.

Sierp base 2 odd-n all remaining 7 k's now at n=445K, 2 of which are being double-checked.

Sierpinski base 2 even n's / Sierpinski base 4 :

I reached the 2M limit for k = 23451, no prime...
The last exponent tested was n = 1,999,922
I am unreserving this k for now.

k = 60849 is now tested up to n = 1,965,606, no prime, continuing up to 2M...

To continue this work further, we need now much sieving, so I decided to start a big sieve operation :

I launched the Srsieve program with an input file containing the 9 remaining k's for Sierpinski base 2 even n's (2 k's) and odd n's (7 k's) and the range of n = 1 to 8,388,608 base 4, which is 16M base 2 !
I wish to continue this work on one machine as long as needed, so the resulting sieved files might be splitted and distributed from time to time to users when sieved enough, both for first or double checking...
Suggestions for organizing the distribution would be welcome!

Riesel Base 2 odd n's :

k = 133977 is now tested up to n = 491633, no prime, continuing up to 512K
I am starting to test k = 86613 from 256 to 512K, so I reserve it for now.

A reminder :
The 16 files (for n = 256K to 2048K) are now sieved to 569.7 billions ;
