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. :-) Fri Jun 1 10:06:56 2012 matrix is 90270707 x 90270879 (39725.3 MB) with weight 11308345602 (125.27/col) Fri Jun 1 10:06:56 2012 sparse part has weight 9420766130 (104.36/col) |
