Per this earlier post, attempting to get timing for one t70 curve for M1277 (and veer back onto the original thread topic) I ran the following Windows cmd line script:
Code:
: for ecm digit levels bounds and curve counts tables see : https://members.loria.fr/PZimmermann/records/ecm/params.html set prompt=$d $t $p$g set exponent=1277 echo batch script launching gmpecm at %date% %time% >>gmplog.txt ecm maxmem 6144 v v v save m%exponent% chkpnt ckp%exponent% 2900000000 >>gmplog.txt >gmplog.txt echo gmpecm terminated at %date% %time% >>gmplog.txt echo.>>gmplog.txt "Using B1=2900000000, B2=82640965106716, polynomial Dickson(30), sigma=0:1635118019924123710" and over a dozen variations on "Computing roots of G took 367257ms, 94347264 muls and 8192 extgcds Building G from its roots took 229166ms Computing G * H took 36208ms Reducing G * H mod F took 51886ms" for an unknown fraction of completion of stage 2. So, changing the ecm line to the following and trying stage 2 again, which can be left to run while I work on some toolongdelayed other things unrelated to number theory. Code:
ecm maxmem 6144 v v v save m%exponent%s2 resume ckp%exponent% 2900000000 >>gmplog.txt

Not an electrical engineer so I have no clue what you're on about.
Unless this is just chalsall code for "are you an electrical engineer?" in which case you've got your answer. Never mind the usefulness of Ken's post, isn't 56 minutes a rather short time to give him to answer your question? Last fiddled with by charybdis on 20220609 at 01:47

Chris, the last three posts are triggering something that will:
1. help you catch your breath 2. give others time to respond to you without you posting more "are you chicken?" posts once every 10 minutes. HTH.
