I am half inclined to take 12m5_253 too, and half inclined to see your post as a reservation of 12m5_253 in rather peculiar form. Please advise.

My post was not intended as a reservation, nor was I attempting to say anything at all about 12p11_253. My reference to your post was simply about the part of it that mentioned finishing sieving, as I was attempting to discuss finishing sieving on a different number (12m5_253).

Although now that I look at it, 12p11_253 appears to have the same issue as the one I mentioned for 12m5_253: over 250 work units have gone missing. You say you'll take it when the sieving is finished, but all indications are that the sieving will never finish. The server doesn't think there are any pending work units, and AFAICT, none has been returned in a while.

Linear algebra on 12p11_253 should be finished here by Sunday morning - I ran a wget -c, noticed there hadn't been any more relations, and started filtering.

Would you like me to take 12m5_253? I expect there to be enough relations now, and the hardware I have access to is chunky enough that I don't care whether the matrix is 13M or 20M.

If you think there are enough relations to build a decent matrix, then by all means go ahead.

But my question about how the server accounting works still stands: what happened to all of those work units for both of these numbers? I suspect it's one that Greg will have to answer.

I am off on a short cycling trip in the Netherlands (Rotterdam - Vlissingen out along the outer dykes and back along the inner dykes); 3p2_583 and 12m5_253 will be finished by my return.
