May I reserve GW_3_453 & GC_6_279?

debrouxl 2013-08-25 14:48

Mathew: reserved for you :smile:

RichD: 14e has been maxed out for that job, though :no:
Greg ?

RichD 2013-08-25 15:18

I think a lot of corrupt WUs were returned, and the dup rate is over a third.

You can unreserve it from me if you want, or I can pick it up again after I return from my trip in mid-September.

Because of the coefficient size, the difficulty was just too high for 14e. I'll handle this one.

RichD 2013-08-25 18:21

Could you finish sieving on the algebraic side? It would be inefficient with low yield and high dups but you are so close but yet so far away...

RichD 2013-08-25 18:52

I've got time for a couple small ones.

May I reserve GW_9_227 ?
