Your computer at the service of science, exclusive interview to the director of seti@home and BOINC: David P. Anderson
June 13, 2010
Exclusive interview for seti.cl

David P. Anderson is a research scientist at the Space Sciences Laboratory at the University of California Berkeley. It leads the SETI@home, BOINC, Bossa and Bolt projects.
Thanks to the development of seti@home, more than 5 million users worldwide were able to form the largest supercomputer, thereby creating the concept of volunteer computing. Accordingly, BOINC was created, which allows the participation of many other projects, which you can see in detail here.
Spanish version here.


David Anderson,Matt Lebofsky and Jeff Cobb in the SETI@home machine room, a converted wiring closet that contains about 50 computers in 3 full-size racks.

For how long have you been working for seti@home and BOINC? How the idea came up?
David Gedye – a friend of mine, and a former student – had the idea for SETI@home in 1994, and he organized the project.
David and I envisioned the use of volunteer computing not only in radio SETI but in all areas of science.
By 2002, there were a few big volunteer computing projects – SETI@home, Folding@Home, GIMPS.
We had succeeded in harnessing a huge amount of computing power, but it wasn’t being alloted to scientists in a good way.
So I decided to develop software that would let any scientist create a volunteer computing project, and would let volunteers donate computing power to any set of these projects, not just one. The goal of this software – BOINC – is to create a dynamic “scientific computing ecosystem” in which projects compete for volunteers, the projects doing the best science get the most computing power, and volunteers have an incentive to learn about and evaluate current scientific research.
The National Science Foundation (a U.S. funding agency) supported this vision, and has funded the development of BOINC from 2002 until the present day.

What’s your inspiration to keep working on distributed computing?
I think volunteer computing is the future of scientific computing. The amount of computing power in consumer products – especially GPUs – vastly exceeds that of cluster, grids, and supercomputers. In addition, I hope that volunteer computing will encourage people to think about science, the scientific method, the value of skepticism, time scales beyond the current moment, and spatial scales beyond the immediate surroundings. These types of thought are under constant attack.
For me personally, it’s fun and satisfying to work on BOINC. There are many challenging technical problems in converting a huge set of diverse, untrusted computers into a reliable computing resource. And of course, every computer programmer dreams of having their creations used by lots of people.

Is there any significant result on any BOINC projects?
Most BOINC projects produce a constant stream of scientific results and publications: Climateprediction.net has done the best predictions of century-scale climate change, IBM World Community Grid has discovered drug candidates, PrimeGrid has found new prime numbers, and so on. SETI@home hasn’t found ET, but SETI@home is not representative of volunteer computing in general.

What are people favourites areas of research?
What’s more important: to find new drugs to treat cancer?
To understand the molecular basis of cancer?
To mitigate the environmental factors that cause cancer?
Or something more universal, like finding the Higgs boson, gravitional waves, or ET?
There’s no right answer, of course. Everyone has their own values and their own opinions. The beauty of volunteer computing is that it gives people a reason to think about these questions, and the power to act on their conclusions.

What is human-based computation? Are people collaborating and understanding this concept?
Most science research projects involve a web of interdependent activities: forming theories, designing experiments, building instruments, analyzing data, and so on. Computers can help with some of these things, but science remains an essentially human activity.
Some research involve tasks that the public – perhaps with a little training – can do via the Internet. Pioneer projects like Stardust@home and Galaxy Zoo used this approach to analyze lots of images.
People – including me – are becoming interested in exploring other types of research in which the approach might be useful.
This is a bit like volunteer computing, but in some ways harder because people are far more diverse than computers.

What are your expectations on distributed computing and citizen science?
We’ve made only small progress toward the grand goal of a scientific computing ecosystem. There are more volunteer computing projects now – about 50 – but not many new ones. Volunteer computing hasn’t entered the mainstream of scientific computing, and it hasn’t achieved public awareness on a large scale.
The main difficulty I see is that, even with BOINC, few scientists have the computer resources or skills to operate a volunteer computing project. The solution, I think, is to locate projects at an institutional level: instead of SETI@home, for example, we should have UCBerkeley@home, which provides computing power to all UC Berkeley researchers, and is operated and promoted by the University.
A small group of people is working towards the grand goal, and progress is being made on several fronts.
I feel that we’re approaching a “tipping point” after which things will really take off.

Any greetings to the spanish speaker community?
I lived in Ecuador as a teenager and have tremendous love and respect for Latin American culture and people.
I hope to form collaborations with Latin American scientists, partly so that I can travel there often and practice my Spanish, which has eroded considerably.

您的计算机在为科学而服务
——独家采访seti@home及BOINC主管David P. Anderson

2010年6月13日
seti.cl专访

David P. Anderson是加州伯克利大学空间科学实验室的研究科学家。这个实验室引领了SETI@home, BOINC, Bossa和Bolt项目。

多亏了seti@home的发展,世界各地超过五百万的用户可以联合成最大的超级计算机,从而创立了志愿计算这一概念。随之而来的就是BOINC的诞生,这一平台接纳了其他项目的加入,你可以从这里了解更多细节。
西班牙语版本在这里。


David Anderson, Matt Lebofsky和Jeff Cobb在SETI@home的机房内,这个机房改造自布线房,有3个全尺寸挂架,放置了50台电脑。

你为seti@home和BOINC工作了多久?这个想法是怎么冒出来的?

David Gedye是我的一个朋友,同时也曾经是我的学生。他在1994年产生了SETI@home这个想法,于是他就组织起了这个项目。

David和我预见了志愿计算在搜寻外星无线讯号以及所有其他科学领域的应用。

截止至2002年,已经有一些大型的志愿计算项目,如SETI@home, Folding@Home, GIMPS等。我们成功地利用了大量的计算能力,但却没能很好地将之分配给科学家使用。

所以我决定开发一个软件,能够让科学家自主开发志愿计算项目,同时能让志愿者们将计算能力贡献给其中任何项目,而不再仅仅局限于一个项目。这个软件BOINC的目标就是创建一个动态的“科学计算生态系统”,在这个系统里不同的项目各自吸引志愿者的加入,从而最好的科学项目将获得最多的计算能力,同时志愿者也被激励来了解并评估现今的科学研究。

国家科学基金会(一个美国基金会组织)支持这一愿景,并从2002年起至今都在拨款给BOINC的开发。

是什么激励着你持续不断地为分布式计算而工作?

我认为志愿计算是科学计算的未来。在消费产品——尤其是GPU——中存在的计算能力,大大超过了集群、网格和超级计算机。另外我希望志愿计算能鼓励人们思考科学、科学方法、怀疑主义之价值、超越当前时刻的时间标度,和超越当前环境的空间标度等问题。这一类的思想正经受不断的挑战。

就我个人而言,为BOINC工作是有趣且令人满意的。有许多具有挑战性的技术问题,比如将大量相异且不兼容的计算机转化并组成一个可靠的计算资源。当然,每个计算机编程员都梦想着他们的作品能被许多人使用。


Jeff Cobb, David Anderson和Matt Lebofsky正在看着Matt的故障电脑。在Matt身后就是David的办公桌,墙上有一幅Half Dome (Yosemite)的图片和一张他签署给自己的SETI@home计算证书。

有没有什么BOINC项目得到了令人瞩目的结果?

大部分BOINC项目产生了持续的科学结果和发表。比如,Climateprediction.net完成了最佳的世纪跨度气候变化预测,IBM的World Community Grid开发了备选药物,PrimeGrid发现了新的素数,等等。虽然SETI@home没有发现外星人,但是它并不能代表志愿计算这个整体。

人们最喜欢的研究领域有哪些?

究竟哪个更重要?是发现治疗癌症的新药物?了解癌症的分子基础?节制引发癌症的环境因素?还是更普遍的问题,如发现希格斯玻色子,引力波或者外星人?

这一问题当然没有正确的答案。每个人都有自己的价值观和意见。志愿计算之美就在于它促使人们思考这些问题,并为实现其结论提供实践之道。

什么是基于人的计算?人们能理解这一概念并协作吗?

大多数的科学研究项目涉及一系列相互依存的活动:形成理论,设计试验,设置仪器,分析数据等等。计算机能帮助其中的一些环节,但是科学从本质上而言依然是一项人类活动。

某些研究包含一些即使只受过少许培训的公众都能用互联网完成的任务。先锋项目如Stardust@home和Galaxy Zoo正运用这一方式来分析许多图像。

包括我在内,人们正变得有兴趣去探索可使用这一方式的其他类型的研究。

这有些像志愿计算,但是在某些方面而言更加困难,因为比起计算机来,人类的相异性更甚。

你对分布计算和公民科学有什么期望?

我们仅仅在实现科学计算生态系统这一宏伟目标的道路上前进了一小步。现在有更多的志愿计算项目,总数大概有50个,但新项目并不多。志愿计算还没有进入主流科学计算领域,在大范围上来看也没有获得公众影响。

我认为即使对BOINC而言,主要的困难在于只有少数科学家拥有计算机资源或者技术来运行志愿计算项目。我想,解决方案就是从研究所层面上落实项目。比如,作为SETI@home的替代,我们应当运行UCBerkeley@home,这个项目会面向所有UC Berkeley的研究员提供计算能力,并由大学来承担项目的运作和推广工作。

已经有一小组人在为实现这个宏伟目标而努力工作,他们在一些方面已经取得了进展。

我觉得我们正在接近一个转折点,在这之后项目将真正起步。

能不能对西班牙语分布计算社区说两句?

我的童年是在厄瓜多尔度过的,对于拉丁美洲文化和族群我抱有极大的热爱和尊敬。

我希望能和拉丁美洲的科学家们建立合作,这样我就能经常前往那里并练习我那退步的厉害的西班牙语。

回复 5# Nye

    Higgs bosen, gravitional waves -> 直接翻译出来吧,希格斯玻色子,引力波

总体不错,但有几个句子似乎不太通顺,建议再小修一下,比如:

在这个系统里各种不同项目争取志愿者的加入。。。
人们——包括我自己——逐渐变得有兴趣去探索其他类型并可使用这一方式的研究。。。
