= Create a Virtual Campus Supercomputing Center (VCSC) =

Universities can use BOINC to create a 'Virtual Campus Supercomputing Center' (VCSC).
A VCSC can provide researchers with the computational power of a large cluster or supercomputer,
for a small fraction of the cost.
A VCSC is a BOINC project whose applications are supplied by campus researchers.
The computing power is supplied by campus PCs - computing lab machines,
desktop and laptops belonging to faculty, staff, and students,
and home PCs belonging to university alumni and the public.

As an example, suppose that a VSCS recruits the participation of 10,000 PCs, running an average of 50% of the time.
In terms of computing power, this is roughly equivalent to a 5,000-node cluster,
for which the initial hardware cost is roughly $5 million,
with ongoing yearly energy and maintenance costs of at least $1 million.
The VSCS, in contrast, has hardware costs of about $10K.

== Creating a VCSC ==

A VCSC is typically created by a campus unit involved in computing and information technology,
by a research unit, or as a collaboration between such units.
It involves the following functions,
which typically would be carried out by different personnel:

* '''Application identification and porting''': This involves canvassing campus researchers, identifying those with computationally-intensive problems that map well to volunteer computing. The applications used by those researchers are then ported to BOINC, and mechanisms set up for the researchers to submit jobs and get results.
* '''Server setup and maintenance'''. This involves setting up BOINC software, and other required open-source software, on a Linux computer. A low-end server (~$10K) is typically sufficient even for large numbers (tens of thousands) of participating nodes.
* '''Resource recruitment and client deployment'''. This involves several activities: working with the campus IT department, and with other units that manage campus desktops and PC labs, to install BOINC on as many PCs as possible; working with dormitory IT management to encourage its deployment on student PCs; creating PR events, such as competitions between student groups to contribute the most computing power; and working with alumni organizations to publicize the project and encourage the participation of alumni home PCs. This function also includes publicity, via mass media, campus media, and Internet channels such as periodic emails to volunteer participants.

== Benefits of a VCSC ==

The benefits of creating a VCSC include:

* It creates a new pool of computing power, available at little or no cost to campus researchers.
  This resource enables previously infeasible research, and may attract prospective faculty.
* It creates a path by which computational scientists can use distributed computing; many of these scientists lack the expertise and resources to do it themselves.
* It creates a new outlet for 'school spirit' which directly contributes to the primary mission of the university.
* It generates publicity for the university and its research.

== Example ==

The University of Westminster in London has created a campus desktop grid using BOINC,
which is estimated to save it £125,000 per year.
Details are
[http://www.westminster.ac.uk/abo ... thousands-of-pounds here].

== Getting started ==

Technical information about porting applications and setting up a BOINC server is [ProjectMain here].
Budget at least a few person-months for getting a working system running.

If you have questions about setting up a VCSC, please [ProjectPeople contact us].

= Create a Virtual Campus Supercomputing Center (VCSC) =
创建虚拟校园超级计算中心(Virtual Campus Supercomputing Center)

Universities can use BOINC to create a 'Virtual Campus Supercomputing Center' (VCSC). A VCSC can provide researchers with the computational power of a large cluster or supercomputer, for a small fraction of the cost. A VCSC is a BOINC project whose applications are supplied by campus researchers. The computing power is supplied by campus PCs - computing lab machines, desktop and laptops belonging to faculty, staff, and students, and home PCs belonging to university alumni and the public.
高校可以使用BOINC创建虚拟校园超级计算中心(VCSC)。一个虚拟校园超级计算中心可以只花费一小部分成本就为研究人员提供一个大的集群或超级计算机的计算能力。 一个虚拟校园超级计算中心是一个由校园里的研究者提供应用程序的BOINC项目。计算能力是由校园电脑——计算实验室的机器,教师、职员、学生的台式机和笔记本电脑,以及大学校友和公众的家用电脑提供的。

As an example, suppose that a VSCS recruits the participation of 10,000 PCs, running an average of 50% of the time. In terms of computing power, this is roughly equivalent to a 5,000-node cluster, for which the initial hardware cost is roughly $5 million, with ongoing yearly energy and maintenance costs of at least $1 million. The VSCS, in contrast, has hardware costs of about $10K.
举个例子,假如一个虚拟校园超级计算中心能募集到万台个人电脑参与其中,平均有50%的时间在运行。在计算能力方面,这是大致相当于一个初始硬件成本在500万美元左右的5000节点的集群。而要维持这样的集群,每年能源消耗和维护成本至少要花费100万美元。相比之下,虚拟校园超级计算中心只需花费约1万美元的硬件成本。

虚拟校园超级计算中心的创建

A VCSC is typically created by a campus unit involved in computing and information technology, by a research unit, or as a collaboration between such units. It involves the following functions, which typically would be carried out by different personnel:
通常虚拟校园超级计算中心是由学校里的计算和信息技术部门或是科研部门创建,亦或者是在这两个部门的协作下创建。它包括以下功能,这些功能通常会由不同的人员进行:

* '''Application identification and porting''': This involves canvassing campus researchers, identifying those with computationally-intensive problems that map well to volunteer computing. The applications used by those researchers are then ported to BOINC, and mechanisms set up for the researchers to submit jobs and get results.
*应用程序的认定与移植:这需要详细调查学校里的研究者,认定那些计算密集型问题能很好地与志愿相结合。那么,那些研究者所使用的应用程序就可以移植到BOINC平台上,然后为那些研究者提交任务和获取结果设立相关机制。

* '''Server setup and maintenance'''. This involves setting up BOINC software, and other required open-source software, on a Linux computer. A low-end server (~$10K) is typically sufficient even for large numbers (tens of thousands) of participating nodes.
*服务器的安装和维护:这包括在一台Linux主机上安装BOINC软件和其他必要的开源软件。即使是有大量(数万)节点参与的项目,一款低端(1万美元以内)的服务器通常就足够了。

* '''Resource recruitment and client deployment'''. This involves several activities: working with the campus IT department, and with other units that manage campus desktops and PC labs, to install BOINC on as many PCs as possible; working with dormitory IT management to encourage its deployment on student PCs; creating PR events, such as competitions between student groups to contribute the most computing power; and working with alumni organizations to publicize the project and encourage the participation of alumni home PCs. This function also includes publicity, via mass media, campus media, and Internet channels such as periodic emails to volunteer participants.
*募集资源与客户端部署:这涉及到几个活动:与校园IT部门以及其他管理校园台式机和PC实验室的部门合作,尽量多地在这些电脑上安装BOINC。与宿舍IT管理部门合作,以鼓励其在学生电脑上部署客户端,举行公关活动,比如在学生群体之间举行比赛,以使他们贡献最大的计算能力。与校友组织合作以宣传该项目,并鼓励校友的家用电脑参与进来。这个功能还包括宣传,通过大众媒体、校园媒体和互联网等渠道,比如定期给志愿者发送电子邮件。

在医院打点滴时所作,仅供参考。。

第一段:认为application并非指指应用程序,而是单纯的应用的意思,也就是说项目是用来干什么的,即项目的研究内容、方向。于是出现下边这条意见:
一个虚拟校园超级计算中心是一个由校园里的研究者提供应用程序的BOINC项目。
虚拟校园超级计算机是一个BOINC项目,它可以处理由校园中研究者所提供的数据。

同一段最后一句,提供前面加个 共同


第二段:
第一句,平均有50%  前面加  并且这些电脑


第三段:
最后一句,进行→实现


第四段:
这需要详细调查学校里的研究者,认定那些计算密集型问题能很好地与志愿相结合。那么,那些研究者所使用的应用程序就可以移植到BOINC平台上,然后为那些研...

第七段:
使校园研究人员的成本降低,甚至没有成本。
降低、甚至免去研究人员的成本。


第八段:
途径→捷径


第九段:
“校园精神”能够直接地贡献给该大学的主要任务。
“校园精神”能够直接地为该大学的主要任务出分力。
