Re: ECM found factors, why so many repeats?

Workunits are NOT splited based on different ranges! ECM, the eliptic curve method, is a trial factoring method. For a batch we have to run different trials, all starting with a different random seed. So all computations are different, they are different trials. For "easy" factors it is therefore p...

Re: ECM found factors, why so many repeats?

To find a factor thousands of workunits have to be computed. This is done in parallel by hundreds of user. So if an easy factor is found it is possible, that the factor is found by many user in parallel. As fast as the server gets a found factor it cancels all not yet sent out workunits and if a cl...

ECM found factors, why so many repeats?

I'm very curious to know why, at the page: http://www.rechenkraft.net/yoyo//y_factors_ecm.php it repeats the same factors found, over and over again. Why is this happening?
