Many years ago I tried larger k in LLR and noticed that there was some limitation (maybe k<2^53, I can't remember). What is the current size limit for k in LLR? Last fiddled with by Thomas11 on 20130815 at 19:37

Here is for convenience the input file in NewPGen format needed for LLR. Please help yourself to cut out your ranges.
It would be nice if some of you could post some comparative timings for LLR and PFGW (PRP test). BTW.: I'm already running a new sieve for the candidates up to n=1M (I've completely underestimated your interest and machinery in this subproject). The new sieve file will be ready for testing around Monday next week. Last fiddled with by Thomas11 on 20130815 at 19:56

My LLR ver. 3.8.8 on a 64bit Mac was crashing on these numbers, but ver. 3.8.9 works fine.
Exe times: n=498496, 424 sec n=730004, 965 sec (FFT len = 72k) The CPU is I5 at 2.7GHz (only one LLR client running on a 4core machine)

Good to see LLR can be used..here are my comparative times:
pfgw: 22544089918041953*3*5*11*13*19*29*37*53*59*61*67*83*101*107*131*2^6123751 is composite: RES64: [29838CC7648D40C8] (930.6872s+0.1715s) LLR: 1480472640274704456611717878515654164205*2^6123771 is not prime. LLR Res64: 1B0F6C3C8C558D4F Time : 800.448 sec Well done Batalov on doing a huge chunk of work, and a prime to boot. 210!!!
