Resuming yafu job (ecm)
Is it possible to somehow configure yafu so hat it would be possible to resume yafu if yafu process is terminated?
I see in docfile.txt that some resumption is possible for seiving, but what about ECM? How complicated would be to implement yafu ECM strategy in script that uses gmpecm directly?

You can use the work option to tell Yafu a certain amount of ECM has already been done

Thanks for the hint!
For example, if I have this kind of output, what value should I pass to the work option? Code:

Nice, thank you!
I will parse the output from yafu to calculate the work done. In this progress line Code:
ecm: 424/2352 curves on C577, B1=3M, B2=gmpecm default, ETA: 14.67 hrs rs Code:
ecm: 424/2352 (to get from t25 to t30) curves on C577, B1=3M, B2=gmpecm default, ETA: 14.67 hrs rs
