2020年回顾
1. The miscellaneous tables were completed. Except for the {2,5} case, this gives the fields for all
imprimitive decics ramified at {p}, {q}, or {p,q} for all primes p < q < 13.
2. Finished many of the lower tiers for the search over ℚ(√-10) (subfield 7).
3. Completed a few more batches for the search over ℚ(√2) (subfield 3), essentially leaving the final monster batch. At our current rate, this batch will take approximately the first half of 2021 to complete.
4. The CPU apps (for 64bit machines) were improved to give an average speed increase of about 35%. Improved GPU apps will be rolled out in the near term.

NumberFields@home: Future of the Project

I've been procrastinating in sharing some news and I finally got around to doing it.

My old thesis advisor who has been backing this project retired in May. I don't actually work for the university, so this means the project has lost is primary benefactor.

The good news is that the university has allowed the project to continue. The bad news is that they will not be supporting any more hardware upgrades. This means when the current hardware fails the project will come to an end.

I'm hoping the current hardware can last several more years. One of the most critical parts is the hard drive, and we just got a new one about 1.5 years ago. Given that the previous hard drive lasted over 4 years, this is a positive.

This news has played into my reasoning on the order of the searches. Given that sf3 is practically guaranteed to be complete, I though it was prudent to use our finite time to first concentrate on sf7. The short term goal is to get sf7 to the same state that sf3 is currently in, which should take us into early next year. At that point, we can either spend the time to finish off sf3 and sf7, or continue on with sf6. Doing sf6 will allow us to find more fields in the finite time we have left, but finishing off sf3 and sf7 will allow us to say with 100% certainty that they are indeed complete. I am leaning towards finishing off sf3 and sf7, but that may change as time goes on.


NumberFields@home项目的未来

我这条消息发得有些拖延了。

我以前的导师,也就是项目的运营者,在5月退休了。我不是学校的教职工(注:NumberFields@home是美帝亚利桑那州立大学的项目),这就意味着项目没有了主管的运营者。

好消息是,学校允许了项目继续运行。坏消息是,学校不会再为项目提供硬件升级。这就是说,当现有的硬件损坏时,项目也就到头了。

我希望现有的硬件能再支撑几年。最关键的部件之一是硬盘,而我们1年半之前才换过新的。考虑到之前的硬盘用了4年多,情况还是乐观的。

这个消息也影响了我决定在剩下的时间里先跑哪些研究。考虑到sf3肯定能跑完,我觉得应该利用有限的时间集中精力跑sf7。短期目标是把sf7跑到现在sf3的完成度,这预计要到明年年初。到那时我有两个选择:彻底跑完sf3和sf7,或者继续跑sf6。跑sf6的好处是能在剩下的有限时间里发现更多成果,而跑完sf3和sf7能让我们拍胸脯说这两方面的发现已经百分之百做完了。我现在倾向于跑完sf3和sf7,不过到那时再决定吧。
