Description
srsieve (and sr1/2/5sieve) is used to create sieve files for one or more sequences. Those software was developed by Geoffrey Reynolds.
These programs are outdated, better use Mtsieve instead.
Download
Commands overview
Help with "srsieve -h".
Installation
Create a folder containing all files.
Creating a new sieve
Example:
srsieve -G -n 1 -N 100000 -P 10000000000 "1000*999^n+1"
Parameters:
-G: create the output file in PRP-LLR format-n 1: lowest value of n to search-N 100000: highhest value of n to search-P 10000000000: highest prime to search for"1000*999^n+1": the sequence to search
After running several files will be created:
"t*_b*.prp": the result file containing all remaining candidates (heret16_b999.prp)"srsieve.log": holding some information of the sieve done (date/time, results)
Continuing an existing sieve file
Using "sr1sieve/sr2sieve" after creating a sieve with "srsieve" is more efficient. To continue the search call this (from example above):
sr1sieve -v -i t16_b999.prp -o t16_b999.prp -P 2000000000000
Parameters:
-v: verbose mode while sieving (for quiet mode use -q)-i t16_b999.prp: the input file-o t16_b999.prp: the output file-P 2000000000000: the highest prime to sieve (also as-P 2e12)
