LLR testing a range of sequences

Purpose

Testing a range of prime sequences for primality using LLR.

Needed

• cllr.exe (or cllr64.exe)
• the sieving result files

Example for WIN

Testing a range 3•2ⁿ-1 to 20•19ⁿ-1 (in general (b+1)•bⁿ-1) create a batch file named "run.bat" with:

set /a base=2
:next
cllr64 -a%base% t17_b%base%.prp

if %base% EQU 20 goto ends
set /a base=%base%+1
goto next
:ends

• -a%base%: create an own resultfile for each base

Call "run" in the command line interface in the directory with "cllr64.exe" and the sieve files "t17_bxx.prp".

Outputs

• llr00xx.ini: *.ini files from cllr64 calls, not needed
• lresu00xx.txt: result files with residues, timings, primes
• t17_bxx.res: if a prime was found, it will be listed here
