In prime.ini add this line: > SkipTrialFactoring=1 That's not what Nathan meant, and it would have the opposite effect of what Torban wants, which is to guarantee that he never LLs an exponent which has not had a full factorisation effort. Nathan is correct that the client can't be set only to do P-1. I achieve this effect by setting SequentialWorkToDo=0, and by ensuring that it never runs out of exponents to P-1. This requires continual hands-on management, collecting new exponents, and unreserving completed ones. One advantage of this, from Torban's POV, is that his chance of finding a factor through P-1 is *increased* if it has not been properly TFed. > Jacek Kolonko Daran G. _________________________________________________________________________ Unsubscribe & list info -- http://www.ndatech.com/mersenne/signup.htm Mersenne Prime FAQ -- http://www.tasam.com/~lrwiman/FAQ-mers
