如果您发现很久没有任务了,那可能是因为您没使用我们新换的地址。诸位若发现有无法连接到到项目等的情况,请尝试在BOINC中重新添加项目。






2013-06-08: NumberFields@home, For users who have been away for a while...
It was brought to my attention that some returning users were unable to connect to the project, probably because they are still using the old url.
So if you haven't visited in over a month, you may be unaware that we upgraded the project servers and have a different url now. If you are having problems connecting, then try reattaching to the project.
Thanks!

Only 25% left to go...
...on the final tier of the decic search over Q(i). Good job all!

2013.07.07:12号子域完成
相关的计算程序已经完成了49个子域中的第12个,并且正向下一个判别式为124的子域进发。
各位干得漂亮!




2013-07-07: NumberFields@home, Subfield #12 complete
The bounded app has now completed subfield 12 of 49, and has started on the next subfield, the one with discriminant 124. Great job everyone!

2013-08-02: 感谢各位在挑战赛中的努力!
这次挑战赛非常成功。许多数据在这次挑战中被处理完毕。具体地说,对Q(i)的搜索基本上已经完成,并且我们已经开始进军接下来的两个子域。再次感谢各位的努力!





2013-08-02: NumberFields@home, Thank you to all challenge participants!
This was a very successful challenge. A large chunk of the decic search was completed. In particular, the search over Q(i) was essentially finished, and inroads were made into the next 2 subfields. Thanks again for all your contributions!

2013-08-07: 第一个
现在只剩下一点点任务包等待处理,我们基本已经可以宣布在第一阶段研究的胜利了。这是一个重大的成就!简单来说,这个研究已经确认了所有度为5的Q(i)的扩张(the Gaussian rationals)^&*&%&×%
@fwjmath

2013-08-07: NumberFields@home, First decic search complete
With only a handful of WUs left to go, we are declaring victory on the first search. This is a major achievement! In a nutshell, this search has obtained all degree 5 extensions of Q(i) (the Gaussian rationals) which are ramified at 2 and/or 5. The final tabulated results will be posted within the next couple of weeks. Thank you!

现在只剩下一点点任务包等待处理,我们基本已经可以宣布在第一阶段研究的胜利了。这是一个重大的成就!简单来说,在这次搜索中,我们得到了所有Q(i)(高斯有理数域)在2或者5处分歧的五次扩张域。在几周之内我们会公布最后的结果列表。谢谢大家!

2013-12-30: NumberFields@home, Subfield #17 complete
At the risk of sounding like a broken record, another subfield is about to be completed. We are now moving on to subfield 18, the one with discriminant 104. Thanks again to all our crunchers!

原始翻译版:冒着打破纪录的风险,另一个阶段已完成。现在正准备运行第18个判别数字104的下一个阶段。再次感谢所有的参与者们!

@fwjmath 数学的东西还请校验一下。

点评

嗯,我觉得可以,不过discriminant一般翻译成判别式就可以了。  发表于 2014-1-1 01:21

2014-10-25: NumberFields@home, Subfield 25 of 49 complete.


I just realized I forgot to officially report the completion of subfield 25; it finished about 2 weeks ago.
We are currently crunching on subfields 26 and 27. Note that we started subfield 26 first because the WU generator had those ready first and the bounded app was desperate for new work.
Thanks everyone!

大意:
2014-10-25:49个数字集合中已经完成了第25个,现阶段正进行26至27号集合的运算。

2018-03-24: NumberFields@home, New application coming soon

In the coming days we will be introducing a new number field application. This one will target degree 7 fields (called septics). The current best bound is 5E6, and this app will increase that to 200E6. This means it will find all degree 7 fields whose discriminant is bounded by 200E6.

Here is some additional information:
1. This search is expected to run for only 5 to 6 months (but could take longer).
2. It will run side-by-side with the current decic app.
3. It will only support the 64bit Windows and 64 bit Linux platforms.

2018-03-24: NumberFields@home, 即将发布新版计算程序
在接下来的几天里,我们将推出一款新的计算程序。该程序的研究目标为,emmmmm...........
妈耶这一行真的看不懂。。@fwjmath
接下来是关于这个计算程序的其他信息:
1.该研究预计持续5-6个月左右(也许会更长)。
2.该程序与现有的decic 计算程序同时发放
3.该计算程序将只支持64位Windows 系统与64位Linux 平台。

这个项目是比较高深了……我翻译一下:

新计算程序的探索目标是七次域,目前最好的上界是5e6,而这个程序将会将上界扩展到200e6,也就是说,它会找出所有判别式小于200e6的七次域。

虽然说吧,即使翻译了,不是学数学的大半也是看不懂……

2019-03-12: NumberFields@home, Septic Results Paper Accepted for Publication

I mentioned a while back that we submitted the results of the septic search for publication. I am now happy to report that the paper has been accepted for publication in the Journal of Number Theory.

I will continue to post additional details as they become available.

Thank you to all our volunteers for making this possible!

2019-03-22: NumberFields@home, GPU app - beta version for linux nvidia

After all these years, we finally have our first GPU app. It's only a beta version for 64bit linux with Nvidia GPUs. Support for other platforms and GPUs will be coming soon.

If you'd like to help test this app, you will need to check the "run test applications" box on the project preferences page. I generated a special batch of work for this app from some older WUs that I have truth for. This will help to find any potential bugs that are still there.

A few potential issues:
1. This was built with the Cuda SDK version 10.1, so it uses a relatively new Nvidia driver version and only supports compute capability 3.0 and up. If this affects too many users out there, I will need to rebuild with on older SDK.
2. I was not able to build a fully static executable, but I did statically link the ones most likely to be a problem (i.e. pari, gmp, std c++)

Please report any problems. I am still relatively new to the whole GPU app process, so I am sure there will be issues of some kind.

Also, feel free to leave comments regarding what platform, GPU, etc I should concentrate on next. I was thinking I would attack linux OpenCL (i.e. ATI/AMD) next as that should be a quick port of what I did with Nvidia. I think the windows port will take much longer, since I normally use mingw to cross-compile but I don't think that's compatible with the nvidia compiler.









=========
2019-03-22: NumberFields@home,发布了Linux系统下NVIDIA显卡的测试版计算程序
目前发布的仅为64位Linux系统下NVIDIA显卡的计算程序(beta)。其他平台和显卡的计算程序将陆续发布。
如果您愿意帮我们测试这个程序,请在项目设置中勾选“运行测试计算程序(run test applications)”。
一些可能会出现的问题:
1.该程序使用Cuda SDK版本10.1编写,所以会需要比较新的显卡驱动版本以及only supports compute capability 3.0 and up 。如果不能满足此条件的人过多,我会考虑用老版本的SDK重建程序。
2.(开发问题)
