Mersenne: Optimal choice of E in P-1 computations

2003-03-09 Thread Daran
Some time ago I raised the question on this list, whether the client's choice of the E parameter was optimal in P-1 calculations. I gave a somewhat handwavy argument in support of the claim that IF it is worthwhile choosing E=4 over E=2, i.e., if the benefits in additional factors found outweigh

Chris, You can avoid a lot of this manual labor by just putting this line in prime.ini SequentialWorkToDo=0 Read undoc.txt to see how it works. What this will do is, force P-1 to be performed first. Anurag _
