srsieve (and sr1/2/5sieve) is used to create sieve files for one or more sequences. Those software was developed by Geoffrey Reynolds.
Help with "srsieve -h".
Create a folder containing all files.
Creating a new sieve
srsieve -G -n 1 -N 100000 -P 10000000000 "1000*999^n+1"
-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 (here
"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
-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
