总不会比我差的

中英文不用翻得完全一致，意译就行
实在不好翻的地方，甚至可以略过

老冬腌菜

只能翻到这个程度了。后面的就不知道该怎么翻了。
看来高二的的确比高三的差不少~

而且估计错误一堆

项目介绍 http://chinapi.vicp.net/project/projectintro.aspx

虽然Pi Segment使用普通的计算机进行计算，但他并不会影响到计算机的正常工作，因为它利用的是计算机的剩余资源
Although the project uses ordinary computers to calculate, it doesn't affect the normal work, as it makes use of the unused computing resource.

所谓剩余资源就是指没有被有效利用的CPU资源。剩余资源是由于计算机当前的运算没有达到CPU的处理能力所产生的。现代的CPU速度越来越快，能够处理的信息也越来越多，但是这也使得它们在大多数时间并没有在全力工作，而是处于闲置状态，CPU的计算能力被白白浪费掉了
The so-called unused resource is the CPU resource not efficient used. It exists when the current calculation of the computer doesn't reach the ability of CPU. Now, the CPU is able to computes more and more quickly, and can deal with more and more information, but the development of CPU means that they don't use all the resource when working and leave unused, so the computing ability of CPU is wasted.

或许您会认为我每时每刻都在使用计算机，它真的会有空闲的时刻吗？答案是肯定的。耳听为虚，眼见为实，您不妨来验证一下：首先打开“Windows任务管理器”，切换到“进程”选项卡，拖动垂直滚动条，您会发现一个“映像名称”为“System Idle Process”的进程（系统空闲进程），请注意它所对应的“CPU时间”，如图所示（点击放大）：
Maybe you consider that you are using the computer all the time, and it will not have free time. It is wrong. You can confirm this in this way: press "Cltr", "Shift" and "Delete" to open the window of "windows task manager", then switch to the Processes tab, you will find a process named "System Idle Process", please notice its "CPU time", as the graph shows. (left click here to watch the original sized picture)



“Windows任务管理器”显示的是当前系统中的进程信息。而“System Idle Process”是系统中一个特殊的进程，每当系统空闲时，它就会被运行。在Windows中，每个进程根据需要轮流使用CPU，而“CPU时间”指的就是对应进程从创建到现在所使用的CPU时间。因此，“System Idle Process”的“CPU时间”就是从开机到现在CPU的空闲时间。您会发现，这个“CPU时间”很大，甚至接近于您本次的开机时间。换句话说，大部分的CPU时间被浪费了，而Pi Segment所利用的正是这部分CPU时间
Windows task manager shows the current process information. "System Idle Process" is a special process of the system, it runs when the system is idle. Every prosess uses CPU according to its need in turn in the OS of windows, "CPU time" means the CPU time the corresponding process has used from it is established. So the "CPU time" of "System Idle Process" shows how long the CPU is idle since logging on. You'll find the "CPU time" of "System Idle Process" is quite long, even close to the time since you have logged on the computer. In other words, most of the CPU time is wasted, and Pi Segment makes use of this part of CPU time.

或许您认为，当CPU空闲时，计算机不会消耗资源。可实际并非如此，尽管现代的计算机都符合一定的节能规范，现代的CPU也支持节能模式，但是实际情况要比预想复杂的多。以下仅就使用者短时间离开或者只进行轻量级任务的情况进行分析；对于长时间不使用计算机的情况，我们建议您直接关闭电源。以一个主流的计算机为例，当CPU空闲时它会转入节能模式，此时它的功耗会减少几十瓦，但其他的部件所消耗的资源并未明显减少，资源的消耗依然很大。更普遍的情况是，您一直在计算机旁使用它，例如写文章、听音乐、看电影、浏览网页等，这些任务对现代的CPU来说九牛一毛，将会有大量的剩余资源被浪费；而此时，显示器（用电大户）肯定不能关闭
Maybe you consider that when CPU is idle, the computer doesn't consume resources. But this is not correct. Although computers now conform to a particular standard of energy saving , and the CPUs now support energy saving mode, the practical situation is much more complex than expected. Here shows the analysis of situation where user leaves for a short time or runs tasks not taking much computing resource; and to the situation where not using computer for long, we suggest you shut down the computer. Take an ordinary computer for example, when CPU is free, it will switch to energy saving mode, then its power will reduce by tens of watts, however, the power of other hardwares won't reduce obviously, and the computer will still consume a lot of resource. More general situation is that you are using the computer all the time, such as writing articles, listening to music, watch movies, browse websites and so on. These tasks is a piece of cake for the CPU, so a lot of unused resourse is wasted; meanwhile, the display, which consumes a lot of power, cannot be shut down obviously.

What is Pi Segment?

Pi Segment is a distributed computing project held by individuals. It aims to propagandize distributed computing, encourage people to make full use of their computational power and challenge the world record of calculating Pi. Distributed computing projects are popular in other countries, but there's none in China. We hope that Pi Segment can change this situation. For more information, please visit the Introduction page of the project.

What is distributed computing?

Distributed computing is a way of computing. In general, any type of computation which includes several computers communicating and cooperating via a network to accomplish one task can be called distributed computing. In a more simple way, distributed computing means to use a lot of computers, in order to obtain faster speed and higher stability, to accomplish a task.

What's the purpose of this project?

The main purpose of Pi Segment is to propagandize distributed computing in China and to try to make full use of computational power. China has started researches in distributed computing long before and has obtained some achievement, for example the China Grid. But so far, there isn't any formal distributed projects for the public to join in. Obviously, that's really a waste of computational resources. We hope that the public would get to know about and join in distributed computing, through the propaganda of this project.

What can I get from this project?

First of all, you won't get any financial reward through participating in this project. This may discourage you as there are projects that actually pay participants for their contribution to the project. But as a non-profit project, we hope that participants would join us only for making full use of their computational power. But that doesn't mean you will get nothing at all. At least you will share the glory of this project and be proud of your spirit of dedication. We are also planning to provide souvenirs for some participants, but it depends on the financial condition of cooperators and sponsors.

Why Pi Segment keeps my CPU at 100% ? Will my computer become slower as I run Pi Segment? Does it do harm to my machine?

Don't worry, it's OK. It's the very signal that your computational resources are made full used.
When designing Pi Segment, we fully considered its compatibility with other applications. First of all, its priority is set to the lowest in order to guarantee that it would slow down and give way to other applications when they need CPU time. Also, it has a low demand to the memory, only 10MB or so. So you don't have to worry about your computer when running Pi Segment. But it's worthy noting that Pi Segment will read and write on the hard disk every several minutes in order to save checkpoints. Of course it isn't a heavy burden on the disk, but it may slow down some of your operations, such as defragging, manual virus scanning and CD-burning. So we suggest that when doing this kind of operations, you can pause Pi Segment to obtain that best performance.
As a matter of fact, all operation, even stop using it for a long time, can do harm to a computer. The point is, if you use your machine correctly, it would produce the greatest possible value. In fact, it won't cause any problem running any ordinary PC in full-loading condition, as long as that PC has passed fine quality check. When testing Pi Segment, one of my PC had run on full load for 20 days or so for some test, and now it is all OK. Of course, it is not recommended to lengthen the running time of your machine only for Pi Segment. You should use your computer as usual, so that the computational resources would be used in the most proper way.

Can I get the source code?

I'm very sorry but the answer is "no". You can't get any source code until this project ends, so the project won't be spoilt by invalid data. But if you are just interested in the theory about how to develop a distributed computing project, you can pay attention to the Research page as we will release some documents on this subject now and then. As a matter of fact, these documents really helps better than the source code.

Pi Segment is a distributed computing project which is held by individuals. It aims to propagandize distributed computing, encourage people to make full use of their computing power and challenge the world record of calculating Pi.

As it calculate Pi by dividing the task into small segments for participants all over the world to crunch, it is given the name Pi Segment.

Though Pi Segment uses ordinary computers to do the calculation, it won't affect the smooth running of your computer as it uses only the spare resources of your computer.

Spare resources here mean CPU resources which haven't been put into use. It is produced by the current computing of your machine not reaching the computational power of your CPU. As nowadays CPUs compute faster and faster and can process more and more things, it also leaves them unused in most of the time. So the computational resources are wasted.

Maybe you would think: will it ever be idle as I'm using it all the time? The answer is "of course". As seeing is believing, you can check this by yourself. Run the Task Manager and click the Process tab. You would find an image named "System Idle Process". Please pay attention to its CPU time, as in this graph (click to zoom out).

The Task Manager shows informations about current processes. "System Idle Process" is a special process which runs whenever the system is idle. In Windows, every process use the CPU in turn to meet its own need, and the "CPU time" of a process is the CPU time this process has used since its start. So the CPU time of "System Idle Process" represents the idle time of your PC since its start. You will find it very long, almost reach the time your PC has been on. In other words, most of your CPU time, which also means computational power, is wasted. What Pi Segment uses to calculate Pi is exactly this part of computational power.

Maybe you will think that when the CPU is idle, the computer won't consume much energy. But the fact is just not that, although PCs nowadays have a standard of energy saving and CPUs nowadays support energy-saving mode. If you will stop using your computer for a long time, we suggest that you can turn it off as in idle, your computer still consume energy but can do nothing. But when you are using your computer to do things such as writing, enjoying music or films and surfing online, a great deal of computational resources are wasted as the tasks above are just a piece of cake for modern CPUs. And at the same moment, you have to turn on the monitor, which consumes a rather large share of energy used by your computer.

Sure, you may doubt about whether it is proper to make your machine full-loaded only to calculate Pi. That's really a controversial question. As a matter of fact, we don't need such accurate with Pi even when calculating the perimeter of our solar system to the precision of atoms. But in a sight of science, every research is nonsense when it is raised and that's why it is called a research. Also, you can join in other distributed computing projects, for example some project purposing to find drugs for cancer, if you think that is more meaningful.

The reasons why we chose to calculate Pi are:

1. Our ability is limited and we can't do computation which needs high costs. In fact, almost 100% of this project is developed by a university student. We have almost no financial support and this project is a non-profit one.

2. Calculating Pi is used widely for benchmark. There's a custom that people love to benchmark a computer by calculating Pi because the computation can be repeated as Pi is a certain irrational number.

3. It won't be controversial. Maybe it can attract more eyeballs to do a simulation of the explosion of atom bombs, but the result may harm the peace. But calculating Pi won't meet such a problem as it is a pure mathematical problem and its result would be published.

4. It is suitable for distributed computing. Though distributed computing is for the whole world, there is still no distributed computing projects in China for the public. We hope to change this situation by Pi Segment. So this project have to be reliable. As the formula for Pi Segment is very clear, it's very suitable for distributed computing.

5.We want to break the world record of the calculation of Pi. The BBP formula allows us to calculate only a certain bit of Pi. But record-breaking is just a hope. If few participants join us, we won't be fast enough to achieve our goal.

You may also doubt about whether running your PC with full load will do harm to it and shorten its life. The answer is: the life time of your computer depends mostly on its quality. The participation of distributed computing has no bad affect on your PC. If your PC can run 3D-games smoothly, then undoubtably Pi Segment would be all OK on your PC, as 3D-games needs all parts of your PC to run in their full speed, but Pi Segment needs only a little memory and disk space, and the frequency of accessing is low. Pi Segment uses mainly your CPU.

You may have other questions, but it is worth a shot. Give it a try!
