Citizen Science Grid是由北达科他大学创建的分布式计算平台,目前已经合并了DNA@Home,SubsetSum@Home,Wildlife@Home三个原有的分布式计算项目,并且包含人工协作类部分。
以下为子项目介绍:
DNA@Home
The goal of DNA@Home is to discover what regulates the genes in DNA. Ever notice that skin cells are different from a muscle cells, which are different from a bone cells, even though all these cells have every gene in your genome? That's because not all genes are "on" all the time. Depending on the cell type and what the cell is trying to do at any given moment, only a subset of the genes are used, and the remainder are shut off. DNA@home uses statistical algorithms to unlock the key to this differential regulation, using your volunteered computers.

SubsetSum@Home
The Subset Sum problem is described as follows: given a set of positive integers S and a target sum t, is there a subset of S whose sum is t? It is one of the well-know, so-called "hard" problems in computing. It's actually a very simple problem computationally, and the computer program to solve it is not extremely complicated. What's hard about it is the running time – all known exact algorithms have running time that is proportional to an exponential function of the number of elements in the set (for worst-case instances of the problem).

Wildlife@Home
Wildlife@Home is citizen science project aimed at analyzing video gathered from various cameras recording wildlife. Currently the project is looking at video of sharp-tailed grouse, Tympanuchus phasianellus, and two federally protected species, interior least terns, Sternula antillarum, and piping plovers, Charadruis melodus to examine their nesting habits and ecology.

[wildlife] maintenance issue
When our systems went down last thursday it looks like there was an issue mounting the storage that housed the imagery and video. They're working on this and hope to have a fix soon. Unfortunately this was done right before a holiday weekend, so the fix might not happen until monday.
Travis Desell on Saturday, November 11th
系统的存储可能出了点问题,影响到了图片和视频。我们的工作人员会尽快修复这个问题。不过因为刚好赶上周末,工作可能要下周一才开始了。

*总体来说,这篇新闻莫名其妙。。我翻了这项目的历史新闻,上次提到“migration ”还是在15年,这里突然说数虚拟机数据迁移出问题。而且,这项目在客户端上还有data export 内容吗?管理员还要来问用户的data export 情况???

2017-12-06: Citizen Science Grid, [all] data export issues?

Are you still experiencing data export issues? I know our IT staff was having some problems with hardware and the recent migration of where the virtual machine for citizen science grid is being housed. It looks like everything is running on my end but I just wanted to double check with everyone in case some export process got lost in the transition.

-------------------
2017.12.06 数据输出问题?
你还会遇到数据输出的问题吗?据我所知,我们的IT人员在硬件上遇上了点问题,所以我们项目所在的虚拟机的数据迁移工作得暂停了。我这的工作貌似一切正常,不过以防万一我还是想再来确认一下诸君的情况,以免出现导出过程丢失的情况。

[wildlife] new searches started
Posted: 11 Feb 2018, 3:45:06 UTC
Hi Everyone -- got some really interesting results from the last round of searches and we submitted a publication on them last week. Will get a copy out to you soon once we find out if it was published! I've started up a new batch of searches so let me know if you have any issues with these.

针对 Widelife 子项目新的研究已启动
在上一批的结果中研究团队找到了有趣的发现,将于近期提交论文并向广大算友提供阅览。新一批任务包已经到位,如有问题请至官方论坛提问。

initial video/slides
12 Apr 2012, 19:08:57 UTC 讨论

Hi Everyone,

From a recent presentation I've made on the project, we have some slides with video so you can get a little idea about what you'll be looking at:

You can download them in keynote format: http://people.cs.und.edu/~tdesell/2012_und_digital_media_showcase.key
or powerpoint: powerpoint - http://people.cs.und.edu/~tdesell/2012_und_digital_media_showcase.ppt.zip

The first 3 videos are old analog camera footage from south Georgia, and the last two videos are recently taken with the new digital camera technology we'll be using for the project in the lekking fields of the grouse in Lost Wood Wildlife Refuge in wester North Dakota.

初始的录像与PPT
2012-08-12

大家好!

从我最近做的一个关于这个项目的演讲中,我们有一些带视频的幻灯片,这样你就可以对你将要看到的内容有一些了解:

您可以下载它们的keynote格式:  http://tdesell.cs.und.edu/talks/2012_nov_15_und_epigenetics.key
或者powerpoint: http://tdesell.cs.und.edu/talks/2012_nov_15_und_epigenetics.ppt

前 3 个视频是来自南乔治亚州的旧的模拟摄像机镜头,最后两个视频是最近用新的数码相机技术拍摄的,我们将在北达科塔州韦斯特的森林野生动物保护区的莱克金草地上进行这个项目。

[all] account manager issues update
2 May 2018, 1:10:01 UTC


Hi All,

It looks like the "team" table in the database had become corrupted and crashed. I repaired the database and it looks like all is working and I'm not seeing any errors on my end. Let me know if this fixed things for you.

cheers,
--Travis




[所有人]账户管理器更新。
2018-05-02

你好,

看起来数据库中的 “team” 表已经损坏并崩溃了。我修复了数据库,目前看起来一切正常,我没有看到任何错误。如果这修复了你的错误,请告诉我。

欢呼,
——特拉维斯




[wildlife] new runs up and going
14 May 2018, 18:21:49 UTC


Hi All,

I've started up some new runs. These are using a different, larger, dataset, so let me know if you see any issues with them.

thanks!


This has caused the RAM requirement to bump to 1.5G, which in turn stops some of my clients from being able to download and run any tasks. These are 1gig cloud servers with 1gig of RAM, I have had to redirect some of them at another project.

Unfortunately, all the reviews I've had from recent publications say we need to move to larger datasets; so there's not anything I can do about the RAM requirements.

We had a couple issues with the server struggling to keep up with some of the previous workunits plus all the new work, and we're working on these. Work flow should at least be improving while we get these sorted out.




[野生动物]新的计算程序出现
2018-05-14

你好,

我开始了一些新的计算程序。它们使用的是与之前不同的、更大的数据集,所以如果您看到它们有什么问题,请告诉我。

谢谢!

----
“这导致内存的需求增加到 1.5G,这反过来阻止了我的一些客户端下载和运行任何任务。这些客户端是 1G 的云服务器只有 1G 的RAM,我不得不给它们分配其他项目。”


不幸的是,我从最近的出版物中得到的所有评论,都说我们需要使用更大的数据集; 所以对于内存方面的要求我无能为力。

我们在服务器上遇到了一些问题,它很难跟上以前的一些工作单元和现有的新工作,我们正在进行尝试解决这些问题。当我们解决好这些问题时,工作流程应该有所改善。
