n=500,000
range= 0-50G
sieving depth= 2500T
candidates= 16,554,793
Avg K per 1M = 331

Please see http://tech.groups.yahoo.com/group/p...m/message/8721

So sieving for both, a twin and a sophie germain is far more beneficial.

thommy how do you do quad sieving and how efficient & fast is it?
please do provide instruction & details.
thanks

It doesn't work that way. We would have to restart the sieve from scratch, and have a k range MUCH larger. Just keep truckin'. Maybe we'll try it a little different next time.

I have a couple of questions:

1) does anyone know what happened with http://www.twinprimesearch.org/

2) Is the sieve "dead"?
2a) Where can I download a file to sieve?

3) Where can I "manually" reserve an llr range?

Thank you

Thank you

1.) The link's dead

2.) No, you can still reserve a range to sieve at the "Sieving and manual LLR reservation" thread here: http://www.mersenneforum.org/showthread.php?t=8137

2a.) The sieve file used to be available for download at http://www.sendspace.com/file/qhiebk but the file expired. I'll upload a new file by tomorrow.

3.) Go to this thread: http://www.mersenneforum.org/showthread.php?t=8137

and post the range you want to reserve. The list of candidates in your reserved range can be found in the sieving file.

I just uploaded the sieve file, and you can get it here:

Thank you I will reserve a couple of T for sieving.
I will have verify first from which point the file is sieved to.

You don't have to. I do all the bookkeeping and you can ask me.

ValerieVonck · 2007-09-30, 16:55

I took the next available range:

5500T => 5510T

Would someone please upload the sieve file again? I'd like to run some tests with it (and possibly reserve a range for sieving later on), but the sendspace web site said that the download (the latest one listed in this thread, at http://www.sendspace.com/file/7nkbip) had expired. How long do these things last before they expire?

Thanks!
