2017-12-05: SETI@Home, Berkeley SETI Research Center undergraduate research internships, summer 2018

Applications are invited for 10-week paid undergraduate research internships at Berkeley SETI Research Center for summer 2018. BSRC is a
world-leader in the search for extraterrestrial intelligence ? the quest for a scientific answer to one of humanity?s oldest questions: Are we
alone in the Universe? Housed in the Astronomy Department at the University of California, Berkeley, the team at BSRC leads the science
program for the $100-million Breakthrough Listen project. Our scientists and engineers are pioneers in the development of software,
instrumentation, and science strategy for the search for intelligent life on other worlds. We have access to substantial amounts of time on
the planet?s largest telescopes, connections to leading players in industry, and we?re based in one of the world?s premiere astronomy
research institutions. We?re also psyched that we get to wake up each day and hunt for aliens.

Current sophomore, junior, and senior undergraduates (including non-US citizens) studying at a degree-granting institution in the US are eligible to
apply. Around 5 - 7 positions will be available. A stipend of $20 / hr (up to a maximum of $8000) will be provided. Details and links to the application form are at https://seti.berkeley.edu/Internship.html

2017-12-06: SETI@Home, Splitters off, again :(

I had to turn the splitters off, again. I underestimated the rate at which we were creating work (damn moveable decimal points!). I thought we could go without adding more space to the database until we had time (tomorrow morning) to delete the old database spaces.

I was wrong, we really zoomed through the files on disk, and we ran out of space. Deleting database spaces is dangerous, so I really want Jeff to check the command script before it gets run. That won't happen until morning. But once it does we'll be back in operation.

Hopefully most SETIzens won't even notice this short absence of work.

-----------------------------
2017.12.06 任务分割器又!挂!啦!:(
我不得已把发包器关掉了,又关掉了。之前我低估了生成WU的速度(都怪小数点,不是我的错!)。我还以为没必要给数据库扩容,结果硬盘满了。。删除数据库的内容是很危险的,所以我十分希望Jeff 能在脚本运行之前再好好检查检查。这项工作明早才会开始,到时候很快就会完成并回复正常。
希望诸君不会发现这次短暂的断粮。

2017-12-07: SETI@Home, Special Fundraiser for Parkes Data Store and GPU development system

Thanks to our collaboration with Breakthrough Listen and their international colleagues, we will soon have the ability to access data recorded at the Parkes Radio Telescope in Australia. For the first time, this will give us full-sky coverage, including the southern hemisphere, in our search for ET. However, due to the enormous amount of data that the 13-beam receiver at Parkes can generate, we will require extra hardware to store and distribute it. We need your help to purchase this.

Thanks to some special offers, one from the Hanson family in memory of Robert W. & Mary P. Hanson, one from Richard Haselgrove in memory of his mother, Jenifer Leech, and one from Mr. Kevvy, we have the possibility to match donations which will allow us to purchase the Parkes Data store server (~$34K) and the GPU development systems (~$10K) we will need for the coming year. For every dollar you donate in this special fund raiser, Mr. Kevvy will match it, the Hanson Family will match it with two, and Richard Haselgrove will match it with two more. That means for every dollar you donate we'll get six dollars towards the purchase of these servers!

Because this is a special fundraiser we'll have special notation on your account page and on the forums. The 12TB disk drives in the Parkes Data Store cost $450. One sixth of that is $75. So, a donation of $75 or more gets you a disk drive icon. The GPUs in the GPU development machine that we will be using for our recording systems at future telescopes are $1500 each, so a donation of $250 or more will get you a GPU icon. And as always, any donation of $10 or more will get you a green star.

But in the end, it's not about the icons: it's about getting the data and making a discovery for the ages. Your help, whether by crunching data or by donating, is always appreciated.

2017.12.07 为Parkes 的数据存储系统和GPU 开发系统募捐
经过我们与Breakthrough Listen 的国际同行们的默契合作,我们将很快能够访问到澳大利亚Parkes 射电望远镜的数据记录。这是我们首次获得包括南半球的全天覆盖能力。不过由于Parkes 的强大数据生产力,我们需要额外的硬件来对其数据进行存储、分发。因此我们需要你们的帮助(purchase this)。
感谢one from the Hanson family in memory of Robert W. & Mary P. Hanson, one from Richard Haselgrove in memory of his mother, Jenifer Leech, and one from Mr. Kevvy ,我们能够使用匹配捐赠的方式购买Parkes 的数据存储服务器(约34K刀)和GPU 开发系统(约10k刀)。这相当于诸君每捐一刀,相当于在服务器的购买中出了六刀!
由于本次活动为特别募捐活动,我们给各位捐款者准备了在账户页面和论坛上的特殊标识(大佬们,出手的时候到了)。12TB硬盘价格为450刀,六分之一即是75刀。所以捐款75刀即可获得一个硬盘的奖章。GPU 开发系统里的一块GPU 大概是1500刀一块,所以捐250刀就能拿到一个GPU 徽章。并且和以前一样,捐10刀或以上就能得到一个小(绿)星星。
话说回来,这不是得不得奖章的事,这可事关到我们明年获取数据的能力和发现小绿人的机会呢。我们感激您的一切帮助,不管是在蒜粒上的还是经济上的。

2018-03-31: SETI@Home, Unexplained database slowness

The database has gotten hung up a couple of times with slow queries. I've restarted it once and that seems to have helped. It'll take several hours to be sure.

If that didn't solve the problem, it probably means the index the server uses to choose workunits to send has gotten corrupted. If I need to rebuild it, we'll probably be down most of tomorrow while I do so.







--------------
2018-03-31: SETI@home ,数据库因不明因素变慢
数据库频繁提示速度过慢。我重启了一次,看起来有点用,不过还是要观察几个小时看看。
如果这也不能解决问题,可能就是服务器选择发送任务包的索引损坏了。要重建索引的话,明天可能会需要停机将近一整天。

2018-04-30: SETI@Home, Dropped packets

The UC data center switched over to a new firewall this morning. Since then packets into and out of the data center have been suffering drops. The Data Center staff is debugging the problem, we'll probably be dropping packets until it's resolved.

SETI@home hibernation
On March 31, the volunteer computing part of SETI@home will stop distributing work and will go into hibernation.

We're doing this for two reasons:

1) Scientifically, we're at the point of diminishing returns; basically, we've analyzed all the data we need for now.

2) It's a lot of work for us to manage the distributed processing of data. We need to focus on completing the back-end analysis of the results we already have, and writing this up in a scientific journal paper.

However, SETI@home is not disappearing. The web site and the message boards will continue to operate. We hope that other UC Berkeley astronomers will find uses for the huge computing capabilities of SETI@home for SETI or related areas like cosmology and pulsar research. If this happens, SETI@home will start distributing work again. We'll keep you posted about this.

If you're currently running SETI@home on your computer, we encourage you to attach to other BOINC-based projects as well. Or use Science United and sign up to do astronomy. You can stay attached to SETI@home, of course, but you won't get any jobs until we find new applications.

We're extremely grateful to all of our volunteers for supporting us in many ways during the past 20 years. Without you there would be no SETI@home. We're excited to finish up our original science project, and we look forward to what comes next.

2020年3月2日
SETI@home休眠
3月31日,SETI@home的志愿者计算部分将停止分发工作,并进入休眠状态。
我们这样做有两个原因:
1)从科学上讲,我们正处在收益递减的阶段;基本上我们已经分析了我们现在需要的所有数据。
2)管理数据的分布式处理需要大量工作。我们需要集中精力完成对已有结果的后端分析,并将其写在科学期刊论文中。
但是,SETI@home并没有消失。该网站和留言板将继续运行。我们希望其他加州大学伯克利分校的天文学家能发现SETI@home的巨大计算能力可用于SETI或宇宙学和脉冲星研究等相关领域。如果发生这种情况,SETI@home将再次开始分发工作。我们会及时通知您。
如果您当前正在计算机上运行SETI@home,我们建议您附加到其他基于BOINC的项目。或使用Science United做天文学。您当然可以将SETI@home留在项目列表中,但是直到我们找到新的应用程序,您才能获得工作。
我们非常感谢所有志愿者在过去20年中以多种方式支持我们。没有你们,就不会有SETI@home。我们很高兴完成我们最初的科学项目,我们期待接下来的发展。
