The quadrillionth bit of Pi is '0'
pi的小数点后第一千万亿个比特位是0

Between September 5, 1998 and September 11, 2000, one thousand seven hundred and thirty-four computers from fifty-six different countries set a new record for calculating specific bits of Pi. The previous record of this type was the calculation of the forty trillionth bit between April 1998 and February 1999, also by PiHex. This will be the final computation performed by PiHex.
在1998年9月5日到2000年9月11日期间,来自五十六个国家的1734台计算机创造了计算pi的特定比特位的最新纪录。前一个类似的纪录是从1998年4月到1999年二月对于pi的小数点后第四十万亿个比特位的计算,这也是 PiHex 创造的纪录。这将会是 PiHex 的最后一次计算。

The calculation took a total of about 1.2 million cpu hours, and was done using 'idle' time slices (cpu time which no other program is using) on systems running windows 95, 98, NT, 2000, and Linux.
这个计算用了大约一百二十万小时的在 Windows 95、98、NT、2000 和 Linux 上的 CPU 空闲时间。

The 'average' computer participating was a 450MHz Pentium II.
参加计算的计算机平均水平是一台450MHz的奔腾二。

The answer, starting at the 999,999,999,999,997th bit of Pi:
从pi小数点后第999,999,999,999,997个比特位开始的结果是:

1110 0110 0010 0001 0110 1011 0000 0110 1001 1100 1011 0110 1100 0001 1101 0011

   ^ Pi小数点后第一千万亿个比特位

or in hexadecimal, starting at the same point:
用十六进制表示为:

E6216B069CB6C1D3


Steve Finch has written an article about the BBP formula, (upon which Bellard's formula, is based) and the algorithm of Bailey, Borwein, and Plouffe, which we use.
Steve Finch 已经写了一篇关于 BBP 公式(基于 Bellard 公式)和我们用到的各种公式的文章。

A good mathematical reference for this topic is the paper which introduced the world for the first time to this type of calculation, written by Bailey, Borwein, and Plouffe. Available in PDF (193K) and Postscript (182K).
一个很好的参考文献就是首次介绍这种计算方法的文献,由 Bailey ,  Borwein , 和 Plouffe 撰写。有PDF版本(193K)和PS版本(182K)。

Due to the size of the output (many megabytes) produced by PiHex, it is not available for download. (It also makes rather dull reading, consisting of what are, for all practical purposes, random numbers). It is however available upon request, by contacting Colin Percival.

I've updated the Top producers page again. My lonely single Pentium 225 seems to be working rather hard; it is up at the top of the list, while other people who have far more CPU power are further down.
I will update the status page soon (really!), unfortunately I've been busy throwing up for the past few days.
我已经再次更新了Top计算者页面。我寂寞单独的奔腾225处理器似乎计算地相当勤奋;它正处于页面的顶端,而其他拥有更快CPU能力的人却远远排在后面。
不久我将更新该统计页面(真的!),不幸的是我在过去几天中已忙于此事。

1998年5月6日
I've just updated the Top producers page. A few new names are on here, and a couple people moved up a bit.
I will be updating the status page soon, but right now I'm concentrating on optimizing the code for K6 and P6 processors. I'm running into a bit of trouble with a lack of support from Intel and AMD, unfortunately, so it may take me a while.
我刚更新了Top计算者页面。一些新名字出现在这里,一些往上移了一点。
不久我将更新改统计页面,但是现在我正关注于为K6和P6处理器优化源代码。不幸的是由于缺少Intel和AMD的支持帮助,我遇到了一些小麻烦,所以这样会花费我一点时间。

1998年4月29日
I've added the 'Top producers' page. The names listed are as in my database. When I don't see any real name in the first e-mail I get from someone, I just enter the portion of their e-mail address before the '@' sign; consequently, the names in the 'top producers' list are not always the real names of people.
PiHex's website is now officially http://www.cecm.sfu.ca/projects/pihex/pihex.html. Please update your bookmarks.
我已增加了Top计算者页面。列在上面的名字与我的数据库中的一致。当我在从某人处得到的第一封电子邮件中找不到任何真实姓名时,我会输入他们邮件地址@标记前的部分作为他们可能的名字。一般地,在Top计算者页面的名字并不都是人们的真实姓名。
PiHex的网站现在变正式化了。

1998年4月21日
I've just finished expanding the PiHex website: I've added this page, as well as a status page. I will have a 'Top producers' page, but I can't put it up yet; I've only gotten results back from six people so far, so I can't really make that page yet.
I'll soon be moving the PiHex webpages over to an account provided for them at the Center for Experimental and Constructive Mathematics here at SFU.

I've updated my biographical information to reflect the fact that I have now officially graduated from high school, and also to mention the entrance scholarship I just won from SFU.
On a more relevant note, congratulations to Kimmo Herranen on being first to break the 0.5 P90 cpu year mark.
我刚更新了我的传记信息来反映我已正式从高中毕业,并且提到了我刚从SFU得到的入学奖学金。
在一个更加相关的通告中,祝贺 Kimmo Herranen 成为第一个打破 0.5 P90 cpu 年度记录的人。

1998年5月31日
Some people have noticed that the 'assigned' lines in the status plots sometimes move downwards between updates -- if you look at the 5 trillionth bit range now, you'll see that there was a range just recently assigned, even though a week ago, it showed that it was 100% assigned.
This is due to my re-assigning ranges after people drop out of PiHex for various reasons.
有些人已注意到,状态区域中的已分配线有时会在两次更新间下降-如果你关注第5百万比特范围,你将发现有部分范围刚被分配,即使一个星期前它显示已100%分配完。
这是部分人由于种种原因放弃PiHex计算后我对其进行的重新分配的结果。

1998年5月21日
I've updated the status and top producers pages.
我已更新状态页面和Top计算者页面。

1998年5月19日
I noticed that the source code for download was only version 4.10. I've replaced it by version 4.11.
I've updated the status and top producers pages.
I've finally managed to find someone at Intel developer support who is willing to help me. Given the continued lack of support from AMD, this means that I'll likely release a version with P6 optimized code first, then release a K6 version later.
我注意到供人下载的源代码版本为4.10。我用4.11版替换了它。
我刚更新了状态页面和Top计算者页面。
我终于找到了某个Intel开发者支持队伍的人来帮助我。依然缺少来自AMD的技术支持,因此我将首先发布一个对P6进行过优化的源代码,对K6优化的版本将延迟发布。

1998年5月16日
The status page is now up to date. I decided to scrap the idea of using Excel, so the plots are now less fancy, but more readable, and also much easier for me to update.
状态页面已更新。我决定放弃使用Excel的想法,因此该区域现在不那么花俏,而变得更适合于阅读,并且更适合我对其进行更新。

After a week of being constantly short on ranges, I started assigning ranges for calculating the quadrillionth bit of Pi on Sunday, September 6. I have also added a status plot for the quadrillionth bit, although so far it doesn't show very much.
Version 5.00 of PiHex is finished, and is being betatested right now. Unless any new problems are found in the next couple of days, I will make it available by the end of the week. Version 5.00 is about 40% faster on P6 architecture machines (PPro, PII, Celeron, Xeon), and about 60% faster on K6s. I expect it to also be faster on cyrixes, but I don't know by how much.
Rob Simmons has redesigned the PiHex web pages to be clearer, and generally better-looking. After releasing PiHex 5.00, I will be uploading the new pages he made.
在经过一个星期经常性的范围短缺,我在9月6日星期日开始分配计算Pi的第百万之四次方比特的范围。我也为第百万之四次方比特增加了一个状态区域,尽管到目前为止它显示的并不是很多。
PiHex的5.00版已完成,正在进行Beta测试。除非在接下去几天中有任何新的问题被发现,否则我将会在本星期末放出该版本。版本5.00在P6架构(PPro,PII,Celeron,Xeon)的机器上将会快40%,在K6系列的机器上将快60%。我期望它在Cyrix的机器上也能快一点,但是我现在不知道能快多少。
Rob Simmons已重新设计了PiHex的网页以使它变得更简洁,整体上看起来好多了。在放出5.0版本后,我将上传他设计的网页。

1998年9月2日
I've modified the formula I use for calculating the statistics for the top producers page to be slightly more accurate. The old formula ended up underrating work done on the forty trillionth bit, and overrating work done on the five trillionth bit.
我修改了用于计算统计数据和Top计算者页面的方程以使它更准确。旧的方程低估了对第40兆比特的运算,高估了对第5兆比特的运算。

1998年8月30日
We have finished calculating the five trillionth bit of Pi. Read about it here.
Meanwhile, we are starting to run out of ranges for calculating the forty trillionth bit of Pi (even after re-assigning ranges from dropouts). Sometime soon, I will start assigning ranges for calculating the quadrillionth (10^15th) bit of Pi.
我们已经完成了对Pi的第5兆比特位的计算。相关信息请点击这里
同时,我们快算完Pi的第40兆比特了(即使已将放弃运算者的部分重新分配)。很快我将开始分配对Pi的第10^15比特位的计算任务。

1998年8月18日
I just realized that I haven't said anything here in two months. Well, here's what's going on:
All the ranges for the calculation of the 40 trillionth bit of Pi have been assigned, but quite a few people have dropped out, so I am reassigning their ranges. However, most people don't tell me when they drop out, and it is too difficult to send multiple e-mails to 50+ people asking them if they are still running PiHex, so when it looks like someone has quit, I'll reassign their ranges. Which means, if you're taking a long time, and you haven't communicated with me recently, send me an e-mail telling me that you still exist.
PiHex has almost finished calculating the five trillionth bit of Pi. Expect something within a week. Assuming I can find a good way to do it, I will send an e-mail out to everyone telling them what the answer is. (If anyone knows of a convinient program for sending out a single e-mail to about 200 addresses, please tell me).
The P6-optimized (Pentium Pro, Pentium II, Celeron) version of PiHex is almost ready. (I've managed to work around the problem I was having with the P6 -- it isn't actually a bug, it is simply a very strange feature). I expect to be betatesting it within a week. I do not need any more beta-testers, I already have enough.
Finally, congratualations to Kimmo Herranen on racing ahead, and passing the 2.5 CPU year mark (of course, having 6 computers helps a bit...).
我刚意识到我已经两个月没在这里说话过了。那么,这里是进展情况:
所有对第40兆比特位运算的范围已全部分配,但是一部分人放弃了运算,因此我正在重新分配他们的部分。然而,绝大多数人在他们放弃运算的时候都不会通知我,而且给50个以上的人群发邮件询问他们是否还在运行PiHex是一件很困难的事,因此当某人似乎已经退出时,我将重新分配他的部分。这意味着,当你运行了很长时间并且最近没有和我联系,请发一封电子邮件给我,告诉我你依然在运行PiHex。
PiHex已经快完成了对Pi的第5兆比特位的运算。期望在一周内完成。如果可以的话,我将把结果用电子邮件发送给所有参与者。(如果有人知道能方便地将一份邮件发送到大概200个邮箱地址的程序,请告诉我)。对P6系列CPU(Pentium Pro,Pentium II,Celeron)进行过优化的PiHex版本已接近完成。(我已试着解决一个与P6有关的问题--它事实上不是一个Bug,仅仅是一个非常奇怪的特性)。我期望能在一周内进行Beta测试。我不需要更多的Beta测试者,我已经有足够的了。最后,祝贺Kimmo Herranen的迎头赶上,超过了2.5CPU年的纪录(当然,拥有6台电脑给了他很多帮助……)

1998年6月14日
There have been some recent problems with the server on which the PiHex web pages reside, due to some new hardware. As far as I know, the problems have now been resolved.
Work on the P6-optimized version of PiHex has been delayed pending an answer from Intel regarding an issue relating to the P6 core, used in the Pentium Pro and Pentium II. It looks like a bug, it acts like a bug, I'm waiting to get an answer on whether it really is a bug.
Meanwhile. I'm doing some preliminary work on the protocols for an automated version, so my time isn't being completely wasted.
由于一些新硬件,PiHex网站所在的服务器最近出了一点问题。据我所知,问题已得到解决。一句未翻译它看起来像一个Bug,表现得也像一个Bug,我正在等待关于它是否真的是一个Bug的回复。
同时,我正在为一个自动版本的协议做一些先期的准备工作,所以我的时间并不是完全被浪费了。

1998年12月20日
Don't worry, I'm still alive ;-). Here's what's been going on in the last two months:
I had hoped to finish calculating the forty trillionth bit by the end of November. Obviously we didn't quite make it, due to several events piling up on top of each other, including three people going on vacation. It looks now like we will finish the forty trillionth bit sometime in the middle of January. After that, of course, all the computers will be working on the quadrillionth bit, so that should go a bit faster.
After a couple months of hacking together communications code for version 6.0 of PiHex, I've decided that actually getting it released is more important than all the features that I wanted to put into it (having one copy of PiHex 'proxy' communications for another, for example). So (assuming that I get my christmas shopping done before I go back to university in the new year) it should come out relatively soon.
别担心,我还活着;-)。这里是最近两个月的进展:
我曾经希望在11月底结束第40兆比特位的计算。显然我们
Many people have told me that they are running PiHex 'until the SETI project is ready'. Such people will not have to quit PiHex in April because the SETI project will be a screensaver and will therefore not use all the idle cycles during normal use. As long as PiHex's priority level (implemented in version 5.10) is set to something less than four, PiHex will not interfere with the SETI project screensaver, and will still get a large amount of work done.
People have been asking me where we will be going after the quadrillionth bit. Once we finish computing the quadrillionth bit, we will have accomplished everything that we set out to do, and so PiHex will stop there (at least until someone challenges our record!)
However, in my effort to prove to the world that idle-time computing (aka. distributed computing, but I prefer the name idle-time computing because distributed computing is also used to refer to java scripts and the like) is useful, I am planning on challenging Kanada's record for a 'classical' computation of Pi (ie, all the digits up to a point, rather than 'jumping in' as PiHex does). This will require two things, namely a lot of disk space, and fast communication. I think that this is practical, however, since many people now buy 6GB hard drives with the expectation that it will be enough for the next three years, and because cable modems, ADSL, and other high-bandwidth options are becoming increasingly common. The code would, of course, be written to only use network bandwidth in 'quiet' periods, and to make sure it left significant amounts of free disk space (so it shouldn't get in anyone's way).
To determine how much support there would be for something like this, I am conducting an informal survey. Please send me an e-mail and tell me what sort of internet connection you have (and if you expect that to change in the next year), how much disk space you could spare (knowing that you could get it back when you needed to), and any other comments you have.

1998年10月29日
PiHex version 5.10 is now available for download. As mentioned below, I think that it fixes the 'overheating' bug, at least in some cases. To upgrade to version 5.10, just download it, and unzip it over the old files.
Because of the added features in version 5.10, most people will probably want to download it.

I have (I think) tracked down the problem with version 5.00. It does indeed cause some systems to overheat which don't overheat when running version 4.11, but there is also a bug which can cause PiHex to report that it is overheating when in fact it isn't.
I will be releasing version 5.10 soon, which fixes this bug, and also adds some long-awaited features, including the option of either setting the calculation thread priority, or having PiHex vary it to match any screen saver or other project client which is using a lot of cpu time.
I would also like to make use of this opportunity to congratulate the editors of Science News on publishing the first error-free article on our computation of the five trillionth bit of Pi.

Several people have had trouble with version 5.00 of PiHex on Pentium II systems. It appears that version 5.00 can cause the cpu to overheat, but it might just be a bug in version 5.00. As a result, I have put version 4.11 back up. If you experience problems with version 5.00, you should use version 4.11, but otherwise you should use version 5.00, since it is faster.

Help, I'm buried by e-mails! Well, not quite, but almost. The New York Times published an article about our calculation of the five trillionth bit on Thursday the 17th, which lead to over 50 new participants, and over 100 e-mail messages. As a result, I might take a bit longer than usual to respond to all of them.
I'm pretty much satisfied that PiHex 5.00 is (relatively) bugfree. As a result, it is now available for download. I have also uploaded the PiHex 5.00 source code.
People running PiHex on Pentiums don't need to download version 5.00, since it only faster non-Pentium cpus. Everyone else, however, should download it, since it is 40-60% faster than the Pentium version.

I'll soon be moving the PiHex webpages over to an account provided for them at the Center for Experimental and Constructive Mathematics here at SFU.
我不久会把PiHEX的网站迁移到SFU的Experimental and Constructive Mathematics中心

Work on the P6-optimized version of PiHex has been delayed pending an answer from Intel regarding an issue relating to the P6 core, used in the Pentium Pro and Pentium II.
意译的:

因为需要等待Intel对于“P6核心”问题的答复,Pentium Pro和Pentium II的优化版本将推迟

news页面

1998年5月6日
I've just updated the Top producers page. A few new names are on here, and a couple people moved up a bit.
I will be updating the status page soon, but right now I'm concentrating on optimizing the code for K6 and P6 processors. I'm running into a bit of trouble with a lack of support from Intel and AMD, unfortunately, so it may take me a while.
我刚更新了Top计算者页面。一些新名字出现在这里,一些往上移了一点。
不久我将更新改统计页面,但是现在我正关注于为K6和P6处理器优化代码。不幸的是由于缺少Intel和AMD的支持帮助,我遇到了一些小麻烦,所以这样会花费我一点时间。

去掉“源”字

http://www.equn.com/pihex/colin.html

concurrent studies是否应翻译成“协作研究”

另外,说一个背景,有利于翻译:

当时的Pentium有一些是有浮点错误的,所以各种地方都提到了P6 core issue,包括区别有BUG和没有BUG的CPU。看起来,一开始作者并不确定是Intel的BUG,这个BUG也耽误了他不少时间;后来在源代码中,作者实际上写了两个程序对不同的CPU分别处理

第 8 楼翻译中,1998年5月11日
I will update the status page soon (really!), unfortunately I've been busy throwing up for the past few days.
不久我将更新该统计页面(真的!),不幸的是我在过去几天中已忙于此事。

后半句读不通,我会尽快更新统计页面(真的!),我已经为这事忙了几天了,但是很不幸还没有完成。

12、13、14 楼 JUST 提出的已做相应修改。
