Hi, I need some help.
I would like to look for a factor of a mersenne prime in a specific area.
For example, for a mersenne exponent of say 40,000,000. I want to use the
Prime95b program, (v19 I guess), to search for a factor in a specific range
from, say, 2^40 to 2^50. I do not understand the ECM factoring instuctions
included with Prime95.
>>You can also edit the worktodo.ini file directly. For example:
>> ECM=751,3000000,0,100,0,0,0,24
>>The first value is the exponent. The second value is bound #1. The
>>third value is bound #2 - leave it as zero. The fourth value is the
>>number of curves to test. The fifth value is the number of curves
completed.
>>The sixth value is the specific curve to test - it is only used in
>>debugging. The seventh value is 0 for 2^N-1 factoring, 1 for 2^N+1
>>factoring. The eighth value is the MB of memory the program should use.
I don't understand how to set the ECM= paramaters to accomplish my goal.
It is my understanding that one can use ECM or 2^p-1 factoring with V19.
Any help would be appreciated.
Thanks
Dan
