Hi Cedric

Congrats on yet another nice prime, and thanks for staying with us all these years! I just checked, the first post of this thread was posted on Oct. 30, 2006.

@kosmaj, thx for the nice reply :)
When I take responsibility, I own up to it :)
And doing this project (off & on) I have learned much about myself
- planning
- responsibility
- patience

I'll keep on crunching for a while (first big milestone) up until 1M
Then I plan a hiatus, then I will restart the sieve for 1M to 50M

Best regards
C

llr testing till 1M completed, no more new primes to report
sieving is started in the 1M -> 50M range
lresults will be uploaded soon

I wasn't awake yet ;)

Thanks, now it works!

ValerieVonck · 2013-04-19, 07:24

on the 27th of April, the candidates from 1M to 50M will be sieved to 25T.

Does anybody have an idea how to sieve the same file on different pc's??

Thank you

It depends on your sieving software:

If you are using sr1sieve, you can run different intervals [pmin-pmax] on the individual machines. All you have to do is to collect the factors found (using the "-f" switch).
For example:

Code:

./sr1sieve -i input.txt -o output.txt -f factors.txt -p 1000000 -P 2000000

After a while you transfer the factors files to your master machine and update the sieve file using srfile, which is part of srsieve:

Code:

./srfile -g --known-factors factors.txt sievefile.txt

(The "-g" switch is to force the NewPGen file format.)

There might also be a similar procedure for NewPGen, but I haven't tried yet...

NewPGen -> Services -> Sieve across several machines -> Duplicates
fill in
- the sievefile-name (npg-format)
- number of machines/files you need
- range of primes to sieve

It will create several files in npg-format with different p-startingpoints in the header.

After sieving you can combine all result-files with
NewPGen -> Services -> Sieve across several machines -> Merge.

newpgen is so slow for a single k compared to sr1sieve that Cedric must be using sr1sieve, right??
