The next project is 2_716P
 

A couple of hours ago we finished allocating tasks in the 5_304P project and swapped over to 2_716P. It will take a few more hours for the last stragglers to return their results and then post-processing on the former project will begin.

The new project, as you may be able to guess from its name, is to factor the 163-digit composite cofactor of 2^716+1. It is one of the Cunningham project's "More Wanted" numbers. It will be somewhat harder than its predecessor. I sieved approximately 1/20000 of the relations we will require when choosing sieving parameters. This is a very small percentage but enough to indicate that it will take around 16000 WU altogether --- though that figure may be subject to revision as we collect more data.

Once your client has started sieving the 2_716P project you may safely delete the directory/directories called projects/5_304P_* and all the contents therein. That should free up a few megabytes of disk space. You should find that projects/2_716P_2/ has been created to hold the data required for the new project.

Once more, thanks for all your efforts so far.

Thanks for the update.

(Hopefully this nonsense will flush through the system in a few days.)
