2017-12-13: MilkyWay@home, New Team Creation Requirement (1 Credit Awarded)

Hello Everyone,

We have noticed an uptick in spam teams being created by users with 0 credits crunched. These teams are often advertising sketchy services and are not created in the spirit of working together to help crunch workunits or build a community. In an effort to combat this, we recently implemented a newer version of reCaptcha during account creation to reduce abuse of the team system by spammers and bots.

This new reCaptcha seems to have helped, but not enough. Effective immediately, we are requiring any new team owners crunch 1 credit to before creating team. In reality, this will not be an issue for anyone signing up for the project to actually contribute to the community. It will however make it vastly more difficult for bot accounts to create teams.

If you have any suggestions for helping us reduce abuse of our website and the team system, please let me know below and we can discuss.

Thank you all for your continued support.

Jake

2017.12.13 设定了新建队伍的门槛(最低一分)

哈喽大家好,我们注意到最近辣鸡队伍的数量有所增长,创建这种队伍的还都是一分没得的用户。这些家伙只知道发广告,也不跑一跑任务。为了遏制这一现象,我们近期对新注册用户的验证码增加了点难度。

这版新的验证码看起来有点效果,不过不够明显。所以我们还对创建团队的资格做了限制:用户要最少有1点积分,才可以创建团队。这点门槛对于正常想要参加运算的算友来说根本不算事,但对那些贴广告的家伙来说,应该是个麻烦。

如果你对这方面问题有任何建议,请在原帖回复。

感谢各位对项目的支持。

你们的渣克

2018-01-06: MilkyWay@home, Validation Inconclusive Errors

Hi all,

There has been some reports of validation inconclusive issues occurring with the Nbody workunits. It seems to be isolated to the nbody app. I believe this coincided with a database issue on our end. I am working on resolving the issue.

Thank you for you patience and continued support,
Sidd

2018-03-05: MilkyWay@home, Scheduled Server Maintenance 3/5

Hey everyone,

We will be temporarily taking the server offline today (3/5) at 1pm to do some further hardware upgrades. This time we are adding a second CPU to the server allow more simultaneous connections.

This maintenance period will likely take longer than the last one as CPUs take longer to install and test.

If you have any questions, please let me know.

Jake

Edit:
Server maintenance is concluded for today. We ended up not being able to complete the upgrade, so we are postponing it for a a week or so.

2018.03.05 MilkyWay@home, 今天要对进行服务器维护
大家好,
我们在北京时间3月5日22:00左右(3月5日 13:00)会将服务器临时关闭,以对部分硬件进行升级。这次我们会给服务器增加一块CPU,这样今后服务器能够建立起更多的并发连接。
本次停机会持续到所有CPU安装并测试完毕。
如果您有任何问题,请与我联系。
Jake

新增内容:停机结束。我们没能成功完成此次升级工作,本次升级将会推迟进行。

哈哈哈哈哈哈哈哈哈哈哈哈哈哈哈哈该不会是买错接口了吧

2018-03-05: MilkyWay@home, Reverting Change to Remove Unreliable Hosts

Hey Everyone,

I am going to be reverting the change to use the built in BOINC use reliable hosts option. It seems to be having unintended consequences to the usability of the project for some users.

In the future, Sidd and I will look into manually removing the worst offenders who are sending back erroring workunits.

For anyone effected, I apologize if you haven't been able to crunch for us recently.

2018-03-05: MilkyWay@home, 为了移除不可信客户端对服务器进行了回档
大家好,
为了使用BOINC平台的“仅使用可信的客户端”选项,我不得不对服务器进行了回档(Jake 没说是对数据还是对设置进行操作)。本次操作可能会对部分用户产生未知的影响。
我和Sidd 今后将会研究研究手动移除恶意用户(故意传回错误的任务包)的方法。
受到此次操作的影响而在近期无法帮我们计算的算友们,请接受我们的歉意。

2018-03-07: MilkyWay@home, Removing Hosts With High Error Counts

Hey Everyone,

I am going to be issuing suspensions to 8 hosts with extremely high error counts (over 1000 in their recent history). If you own one of these hosts and are unhappy with the suspension, please message me and we can discuss removing the suspension.

This is a temporary solution until I can implement a more automated suspension system with occasional retesting of hosts to see if they have been fixed.

Any discussion about how to best implement an automated algorithm can go here and I will attempt to keep up.

Jake

Edit:

I added a feature to determine if one of your hosts is suspended at a quick glance. Any of your suspended hosts will show up highlighted in red on the "computers on this account" page in your account information page. These hosts will not show up as red to anyone else and only you will know if you are suspended.


-----------------2018-03-07: MilkyWay@home, 移除了高错误率的主机
大家好,我准备对八台错误率极高的主机进行挂起操作(记录中有超过1000次错误结果)。如果其中有您的主机,并对此有疑义,请与我联系。
本次操作属于临时措施,今后我会尝试实现更加自动化的甄别系统。
任何与实现甄别系统的算法有关的讨论可以在此直接回复,我会尽量予以答复。
Jake

又:
我添加了一个功能,以便大家更方便地查看自己的主机是否已经被挂起。在“此账户名下的计算机”(computers on this account)页面中,被挂起的主机将以红色显示,此效果仅对你有效,别人看不出来。

Hey everyone,

2018-03-27: MilkyWay@home, Scheduled Server Maintenance 3/27

Hey everyone,

We are going to do a quick hardware upgrade for the server. We will be down for the next hour or so. Sorry for the inconvenience.


Jake

[Edit]

This down period is concluded. We couldn't finish the upgrade due to a bad CPU slot on the motherboard. We are going to defer server upgrades for a while until we decide if it is worth it to replace the motherboard.

Thank you all for your patience,

Jake

2018-04-02: MilkyWay@home, New Runs

Hey Everyone,

I just put up 14 new runs. These are de_modfit_XX_bundle5_NoContraintsWithDisk_1 where XX runs from 09 to 23. Each of these is using a different parameter and star file so its very possible that there was some human error on my part putting them up. They were all tested beforehand but if you see any issues, please let me know with the name of the run that's giving you trouble.

Some of these runs have some extra calculations due to the run requirements so their runtimes will vary slightly. The credits should scale accordingly.

Jake

2018-04-02: MilkyWay@home, 新的模拟任务
大家好,
我刚刚上线了14个新的模拟任务。名称为“de_modfit_XX_bundle5_NoContraintsWithDisk_1 ”,其中XX为09-23中的一个数。每个任务都是用了不同的参数及星体文件,所以我这很有可能出现把文件搞混的问题。这些任务都已经测试好了,不过如果各位发现任何问题,请将任务名及具体症状告诉我。
这里面某些任务根据不同的运行环境,可能会需要额外的计算量,任务得分会根据实际运算量计算。

2018-08-21: MilkyWay@home, New MilkyWay@Home Developer

Hello all,

My name is Eric Mendelsohn, and I am a new developer working on the code for MilkyWay@Home. I am currently working on testing the impact of several parameters implicit within the N-body integrator used in MilkyWay@Home. I am also working on adding new gravitational potential models for the simulated bulge, disk, and halo of the Milky Way Galaxy. If you have any questions involving N-body, I will do my best to answer them as accurately as possible.

Thank you for your support!

2019-01-17: MilkyWay@home, Micromanaging CPU vs GPU Workunit Limits

Hey Everyone,

I will be tweaking some config options on the server to better improve database stability and allow for stockpiling of more workunits by GPU users.
为提升数据库稳定性&方便GPU大户进行屯粮,现执行以下调整:

The new workunit limits should be as follows:
Separation:
600 total
200 GPU (Per GPU up to 600)
40 CPU (Per CPU up to 600)
对于Separation子项目,每CPU、GPU线程允许屯600个包。

Nbody:
120 total
20 CPU (Per CPU up to 120)
对于Nbody子项目,每CPU线程120个包。

Hopefully you guys notice this on your end. If we notice we are running out of workunits more frequently on the server, I will increase the workunit cache a bit.

Let me know what you all think about these numbers and how it is working for you.

Jake

Hey Everyone,

The new server is in and I am working on getting our project set up and migrated over. My current plan is to take the current server offline early on Tuesday and migrate the database to the new server. I'm not sure how long this will take since the database is quite large. Hopefully I will have everything back up and running sometime on Wednesday the 20th. Sorry for any inconvenience this will cause.

2019-03-20: MilkyWay@home, Workunit Credit Issues - Fix Implemented

Hey Everyone,

I have implemented a fix for workunits not assigning credit. Hopefully all newly validated workunits will award credit properly. If you notice anywhere that this is not the case, please let me know.

As for the previously validated workunits which assigned zero credit, I am not sure there is a good way for me to assign credit for them. This would probably require me writing a script to actually alter your credit values based on the number of unrewarded returned results. I am pretty uncomfortable altering credit like this. Please use this thread to discuss and offer your input on this problem.

Thank you all for your patience.

Best,
Jake

至于那些已经被误判为零分的任务,我不太确定有没有什么好方法能重新对其进行授分。我倒是能写一段脚本把各位的积分根据误判的任务数量改过来,但我个人是在是不太喜欢这种方法。关于这个问题我想听听各位的意见。
感谢大家的耐心。

Milkyway@Home: Separation Project Coming To An End
Dear Volunteers,

We are beginning to sunset the Separation project (note that this is different from the N-Body project, which still needs your help!!!). Thanks to your computational contributions, we have completed the goals that we set out to accomplish with this the project, so we are going to shut down the Separation project in the near future. We are planning on submitting a paper containing the final results of the Separation project to an academic journal in the near future. It is possible that the reviewer may request revisions that involve re-running Separation data, in which case we might bring it back for a short time, but until that happens we do not need your computer time for this. We would like to sincerely thank you for all the time and effort that you spent helping us complete this substantial task. We owe the success of the project to you all.

With this announcement comes a few updates to MilkyWay@home: MilkyWay@home will continue to exist, but only as the Nbody project. Because of the complexity of running Nbody tree codes on GPUs, there is little speed-up from running Nbody on a GPU compared to an equivalent CPU. Although we did beta-test a full GPU Nbody application, we have decided not to deploy it due to concerns over maintaining its support; among other issues, supporting GPU Nbody would require changing the GPU code every time the CPU code is updated, and making sure every change is tested and works identically on both platforms. Since we are actively working on extensions of the Nbody code that include such things as the effects of the Large Magellanic Cloud's gravity and the consequences of self-interacting dark matter on the formation of tidal streams, this parallel support would be difficult. So, when Separation shuts down, we will be ending GPU support for MilkyWay@home. This will have the greatest impact on people who crunch lots of Separation work units on high-end GPUs; these users can expect to earn a much lower amount of credit per time than they did before. If you contribute only CPU cycles, your ability to earn credit will be unaffected. We still want as many people to contribute CPU time to MilkyWay@home as possible! However, we understand that if your goal is to use GPUs to obtain a large amount of credit quickly, there are more efficient ways to do this and other projects that can better use your resources.

We would appreciate your input on this because we expect that it will probably take some time for GPU-oriented users to swap that hardware over to different projects. How long would you like us to wait before we shut down Separation?

Again, thank you so much for letting us use your processors! They have not only increased our knowledge of the Milky Way galaxy that we live in, but they have also contributed to five PhD theses and trained dozens of undergraduate students to build and maintain large and complex computing systems. These students and I thank you for your contributions. We will be posting the results of the final Separation project results probably later this year, after they have gone through the peer review process (which takes about six months on average, with wide variability).

Best,
Tom & Prof. Newberg


======================================================【机翻】

Milkyway@Home:the Separation project项目即将结束
尊敬的志愿者们:

我们开始关闭the Separation project 项目(请注意,这与 the N-Body project项目不同, the N-Body project 项目仍然需要您的帮助!!!)。感谢您的计算贡献,我们已经完成了我们设定的目标,因此我们将在不久的将来关闭the Separation project项目。我们计划在不久的将来向学术期刊提交一篇包含the Separation project项目最终结果的论文。审阅者可能会请求涉及重新运行the Separation project数据的修订,在这种情况下,我们可能会在短时间内将其恢复,但在此之前,我们不需要您的计算机时间来完成此操作。我们衷心感谢您为完成这项艰巨任务所花费的所有时间和精力。我们将项目的成功归功于你们所有人。

随着这一宣布,MilkyWay@home有一些更新:MilkyWay@home将继续存在,但只是作为Nbody项目。由于在 GPU 上运行 Nbody 树代码的复杂性,与等效的 CPU 相比,在 GPU 上运行 Nbody 几乎没有加速。尽管我们对完整的GPU Nbody应用程序进行了beta测试,但由于担心维护其支持,我们决定不部署它;除其他问题外,支持 GPU Nbody 需要在每次更新 CPU 代码时更改 GPU 代码,并确保每个更改都经过测试并在两个平台上以相同的方式工作。由于我们正在积极研究Nbody代码的扩展,其中包括大麦哲伦星云引力的影响以及自相互作用暗物质对潮汐流形成的影响,因此这种平行支持将是困难的。因此,当the Separation project关闭时,我们将终止对MilkyWay@home的 GPU 支持。这将对在高端 GPU 上处理大量分离工作单元的人产生最大的影响;这些用户每次获得的信用额度可能比以前低得多。如果您只贡献 CPU 周期,则您赚取积分的能力将不受影响。我们仍然希望尽可能多的人为MilkyWay@home贡献 CPU 时间!但是,我们理解,如果您的目标是使用 GPU 快速获得大量积分,那么有更有效的方法可以做到这一点,以及其他可以更好地利用您的资源的项目。

我们非常感谢您对此的意见,因为我们预计面向 GPU 的用户可能需要一些时间才能将该硬件交换到不同的项目。你希望我们在关闭分离之前等待多久?

再次感谢您让我们使用您的处理器!他们不仅增加了我们对我们所居住的银河系的了解,而且还为五篇博士论文做出了贡献,并培训了数十名本科生来构建和维护大型复杂的计算系统。这些学生和我感谢你们的贡献。我们将在今年晚些时候发布最终分离项目结果的结果,在它们经过同行评审过程(平均需要大约六个月,差异很大)之后。

最好
汤姆和纽伯格教授
