NFS@home challenge

Are we up for this? starts in a couple of days. The project has a lot of 16e work units that need clearing. We could always just help the project out later and not join the challenge if it's too short notice.

The Scottish Boinc Team will be at full speed.

If you are looking for 14e badge please serve yourself because we would like to reach 1000 14e (lasieved) factorizations by the end of the year. The ''Now Sieving'' should be completed as well as the ones in ''Queued''. I am processing C187_121_102 which is to be completed within 9 hours. Then I have reserved P223 (284688...)+1 which I don't know if I will be able to build a matrix because last time I tried to process it it was consuming more than 14GB of memory on my laptop!!!

Overall 300k 14e (lasieved) needs to be sieved by NFS@Home and then all of them post-processed in the back stage to achieve 1000 factorizations.

You're gonna need a bigger boat

If they haven't all been done I'll come and help in December.

I know...
December is too late because we need time to post-process the data.

At Sam's request, NFS@Home will factor the smallest five Bernoulli/Euler numbers. Details of the project are at http://homes.cerias.purdue.edu/~ssw/bernoulli/index.html

These numbers are below.

PDW, think now the server won’t dry as often since I’ve shared my concerns with admin and I’ll be pushing him daily.
