Results not Needed
 

I have a PIII at 933MHz which has been successfully trial factoring exponents for several years. Last year or the year before I changed it from "trial factoring" to "trial factoring to low limits". It always uses the PrimeNet server to get and return work results. It has not reported a successful trial factor result since 06/18/13. The problem appears to be that the last 33 trial factors reported by it to the PrimeNet server "[B]were not needed[/B]".

[U]Is there any way to find out how many of the entries in my worktodo.txt file have already been completed by somebody else so that I won't be duplicating work that has already been done?[/U]

[url]http://www.mersenne.org/report_exponent/[/url] will tell you if you put each exponent in the first box, and clear the second box. It can be a bit tedious if you have a lot to check.

No need for any tedium. Just enter the lowest exponent and highest exponent, and then check the "Show exponents that are assigned to me" check box.

I should clarify that this method will only be helpful if you were assigned the exponents through PrimeNet, and if those assignments are still outstanding (which they should be, as a poached result does not cancel an existing PrimeNet assignment).

Thanks, NBT. That fills in one of my own gaps. OP does state that his work all comes from PrimeNet, too.
