Questions/Problems/Bugs :
Why does /lasieve5f_1.11_windows_x86_64.exe use SSE3 but lasieve5f_1.11_x86_64-pc-linux-gnu doesn't?
(Message 2437)
Posted 30 Jan 2024 by Greg Post: Honestly not sure. The Windows binary was built with MinGW-W64 gcc 4.9.1, while the linux binary was built with gcc 4.1.2. I target arch x86-64, but different options may have been used to compile an included library file. Are you using one of the few early x86-64 CPUs without SSE3 support? |

m1 apple arm port of nfs applications
(Message 2435)
Posted 29 Jan 2024 by Greg Post: Yes, the source code is available at https://github.com/gchilders/lasieve5_nfsathome/tree/windows There is a separate Mac branch also, but the Windows branch should work. However, much of the speed comes from x86_64 asm. An ARM port will need to either use the generic C code or port the asm. |

And we're back!
(Message 2431)
Posted 5 Jan 2024 by Greg Post: The NFS@Home server was unexpectedly caught up in a campus network reorganization. That knocked us offline for a bit over a day. There may be brief outages over the next few days as we get everything settled again, but we are mostly back up with a new IP address. We apologize for the inconvenience. Edit: The site came back up in the US on Friday afternoon PST, but because of a misconfigured firewall it wasn't available worldwide until Saturday afternoon. Again, we apologize for the issues. |

Posted 31 Dec 2023 by Greg Post: We've largely cleared out the smaller numbers in the established factoring projects over the years. It's mostly used now to slowly work through the smaller near-repdigits or if a needed, appropriately-sized Odd Perfect or Aliquot number comes up. |

Computation errors for 16e small numbers
(Message 2390)
Posted 11 May 2023 by Greg Post: There seems to be an issue with the Windows client for degree-7 polynomials on some (but not all) versions of Windows. I'll track that down after we get through finals. In the meantime, numbers with septics have been put on hold. Greg |

Posted 26 Apr 2023 by Greg Post: How do you determine what applications are linked to which Preference Page selections ? Good point. Hopefully is it clearer now. |

WU's failing with EXIT_TIME_LIMIT_EXCEEDED
(Message 2377)
Posted 1 Mar 2023 by Greg Post: I'm a bit confused why increasing rsc_fpops_est leads to a shorter time limit. But I've changed it to slightly above the previous value and added a much larger rsc_fpops_bound. I hope that helps! |

WU's failing with EXIT_TIME_LIMIT_EXCEEDED
(Message 2371)
Posted 26 Feb 2023 by Greg Post: Certainly possible. We are stretching these further than I originally intended when I set those values. I have increased it by a factor of 10 for newly generated wus. |

LOTS of computation errors the last day or so
(Message 2336)
Posted 14 Oct 2022 by Greg Post: That particular number, 283831_43m1, is triggering an error in the siever at an unusually high rate. Not sure why the error rate is so high, but it will pass in a day or so. Sorry for the inconvenience. |
