Post: Recent news: I have just received some workunits for some GNFS number. One of them reads "GB200_25036_0". What is B200? |

16e Lattice Sieve V5

Post: The question here is: when will this app be released for platforms other than Linux? And what are the differences between this and the conventional 16e lattice sieve? |

Post: Good to know? It's common knowledge, so it's not really good to know. But I do note this is one of the ten Most Wanted numbers in the Cunningham project. |

Post: The sieving of 11,290+ is underway. Yes, it's underway, but so is 10,305+! |

Post: In light of recent completed factorisations, I hereby ask questions 6 and 7. Why does linear algebra take place on TeraGrid and not BOINC? How long does it take? In addition, what new numbers are on the consideration list for NFS@Home factorisation now? |

Post: There are no plans to develop one [visual app for NFS@Home]. :/ Yes. Following the currently reserved Cunningham numbers, the 15e sievers will be doing a couple of numbers for the Odd Perfect project. What are the two numbers (or if you can't provide a concise description, provide a link)? |

Post: I do note that 7,355+ is the 100th number factored by NFS@Home. I leaked the factorisation on the "Some questions" thread in the QPB subforum. |

Post: This is a message board for a BOINC project that uses special-q for Oh LOL. Assume special-q is a parameter in lattice sieving Aside from that, I've received the first tasks for 11,290+. Much of page 123 on the Cunningham project website is about the recently-extended base 3 tables. Because of this, a lot of holes and wanted numbers have been left untouched. When is NFS@Home going to factor these numbers? Particularly, I would like to see 10,281+ and 10,281-. |

Post: It seems like 7,355+ has been factored: 2515330297 6907793161 8220867745 7273528948 4404522729 6353222660 8775719348 0305097071 * 4916874214 3759415895 4305310966 7460912512 3792342558 8744451375 1476522168 2782157811 6713493332 1338000377 3870659795 5655149900 757971 = (7^355 + 1) / 8270277554 4295268462 1699584764 9086085761 1172272053 2025972445 6265943017 5387827352 3124077926 68984 http://homes.cerias.purdue.edu/~ssw/cun/page123 http://factordb.com/index.php?id=1100000000020350399 ...M1061 is "on hold". The current siever has run out What is special-q and what is the spring break? I live in Singapore, so all this doesn't make sense to me. |

Post: I figure, then, that 7,355+ and 2,1061- are both in the matrix step. On the PrimeNet page (http://www.mersenne.org/report_exponent/?exp_lo=1061&exp_hi=1061&B1=Get+status) it says there are no factors below 2^63. That looks OK. Now I want to know where I can track the progress of factoring 2,929- on Mersenne Forums, how long it takes to do the postprocessing, and what SNFS difficulty is. |

Post: Your previous post answers all my questions, except part of number 2. I would expect that a fair part of Greg's attention is going to the next step for 2,1061- (a record-setting number, and the most wanted Mersenne number - the last one from George Woltman's list of 2,n- with n < 1200 having no known factor). 2^1061-1. What's the next Mersenne without known factors? Just for reference, here's the full number in base 10: 2470730631 1927565716 8573421287 7408533319 7833223161 8796822389 3530608280 5123046306 9936475077 7605433648 6228891340 8589858290 2707626188 7914242781 6178466724 5343138690 3982455635 5421587484 0182398598 8322905245 0779385675 1325219817 9128990807 9367801947 8139154740 4884040101 6062951113 6882502627 3254703636 0263072077 6443643892 9167613951 But you forgot 7,355+! What's the status of that? |

Post: I have some questions regarding this project: 1. I have received a workunit that begins "S5p433". I have received another workunit that begins "S2p1000b". I can understand the second one (it's for 2,1000+), but not the first - that seems to be 5,433+, but it's not on the Status of Numbers page. What's going on here? And what do the names of the workunits mean in the first place? 2. What's the status of the sieving for 2,1061- and 7,355+? 3. When are the numbers not yet started (ie. 7,365- / 10,305+ / 11,290+ / 2,1000+) going to start? 4. Is there a visual app (like those for WCG and Rosetta@home) that will display the progress of sieving for a workunit? 5. Are there any plans to factor more non-Cunningham numbers (like EM48)? |
