10,305+ is now factored into 75-digit and 135-digit prime numbers. The sieving of 2,1061- is nearly complete. (Really this time!) The sieving of B200 is going well, and once the sieving of 2,1061- is done the V5 applications will also be used to sieve B200. Let's get B200 done as quickly as possible!

Good to know that V5 application will be switched to B200. Right now the lasievef users are at q=179620019. Will lasievef be used until q=420M or in parallel with V5 or V5 will only be used beyond q=420M?
Greg, where are you going to run 2,1061- LA? How many nodes will you be using? This is the type of thing people should know about as in mersenneforum.

Take care,

Carlos

Both will be run in parallel on B200. This will hopefully finish it as quickly as possible.

The postprocessing for 2,1061- is a bit complicated. I anticipate that a portion of it will be run on Trestles at the San Diego Supercomputing Center, and that a portion will be run on Lonestar at the Texas Advanced Computing Center. It will likely use 576 cores, which is 18 32-core nodes at Trestles and 48 12-core nodes at Lonestar.

Yes, really this time. :-)
