    在看CPU相关的手册的时候,经常会看到Die的字样,刚开始不太理解是什么意思,感觉有点像是一颗CPU芯片,但是这样理解还是不够准确。

    后来各种查找,终于找到了Die的准确意思,原来Die是处理器在生产过程中引入的概念。
    总的来说,Die或者CPU Die指的是处理器在生产过程中,从晶圆(Silicon Wafer)上切割下来的一个个小方块(这也是为啥消费者看到的CPU芯片为什么都是方的的原因),在切割下来之前,每个小方块(Die)都需要经过各种加工,将电路逻辑刻到该Die上面。

    为什么晶圆是圆的,这主要是由于晶圆的制作工艺决定的,可以参考文章(https://zhuanlan.zhihu.com/p/30513730)。而为什么切割出来的Die是方的,主要是为了切割方便,并且最大利用Die的面积。理论上,只要晶圆做得足够大,Die的面积足够小,晶圆的利用率就可以无限接近100%。

    对于主流的CPU厂商Intel和AMD而言,他们会将1个或者N个CPU Die封装起来形成一个CPU Package,有时候也叫作CPU Socket,如下图所示:

    由于CPU Die的制作工艺及其复杂,导致CPU Die的大小会很大地影响到CPU Die的良品率,即CPU Die的大小越大,则CPU Die出错的概率越高,良品率也越低,相应的成本也越高。

    在服务器领域,Intel Xeon系列的高端处理器会尽量地将整个CPU Socket做到一个CPU Die上,导致其相应的CPU Die的大小都比较大,这也是其价格昂贵的一个原因。将整个CPU Socket上的东西都做到一个CPU Die上的好处是CPU内部之间各个组件的连接是通过片内总线互联,有更多的资源可以相互共享,这样整体的性能能够更高。

    而对于AMD的EYPC CPU而言,它的每个CPU Socket由4个CPU Die组成,每个CPU Die中包含有4个CPU内核,如下图所示:

    CPU Die之间通过片外总线(Infinity Fabric)互联,并且不同CPU Die上的CPU内核不能共享CPU缓存,而单个Die的Xeon处理器内和所有CPU内核其实是可以共享CPU的第三级缓存(L3 Cache)的。

    我想,这种CPU Die的分布应该也是导致EPYC处理器和Xeon处理器虽然在单核上的性能可能相差不多,但是总体性能赶不上Xeon处理器的一个原因。但是这样也有个好处,就是可以降低成本。

    先介绍几个基本概念:

    lot:工艺制造中按某种方式制成的硅柱

    wafer:中文名晶圆,lot切成的薄片,是集成电路的载体,晶圆越大,在同一圆片上生产的IC越多


    die:wafer根据需要划分不同的区域,每个区域用于生产特定功能的芯片,称之为die

    言归正传:

    我理解的die-to-die是芯片对芯片,这可以是不同lot上的芯片,也可以是不同wafer上的芯片,也可以是同一wafer上不同die的芯片,而within-die则是一个die。在研究IC的process variation(工艺参数变动)时,往往会将之划分为die-to-die(D2D)variations和within-die(WID)variations。在D2D variations中,同一die上的所有device拥有相同的parameters(参数),而在WID variations中,同一die上的device却表现不同。

    1099: Die Die Die!

    Description

    do not play Overwatch
    do not not play Overwatch
    do not play Overwatch
    do not not play Overwatch
    the game will consume your soul
    and drag you to the depth of hell
    I'm not f**king joking around bro
    I woke up at nine pm dawg
    this game is not f**king joke bro
    I stayed up till five pm dawg
    this is a f**king problem dawg
    what the f**k did Blizzard do to make it so addictive
    I never play no Diablo
    I never play no World of Warcraft
    I never f**k with no Hearthstone
    who give a f**k about the Heroes of the Storm
    and you god damn bitches sweet ass 
    that ya boy never put his dick anywhere near no Starcraft
    but Overwatch
    Overwatch
    What the f**k's in Overwatch!
    But you are still playing Overwatch ~2333333333,and now you control a character who‘s name is Reaper. The most powerful skill of him is called Death Blossom, when he use this skill, Reaper will shot around to kill his enemy. Here is the question, you want to know the area of the skill that Reaper can kill his enemy. We assume that each time when Reaper using this skill, he will never move, so we can suppose that he is a point, and the bullets which he shots will fly L meters, because he is so fast that he can shot 360 degrees around him. Now, please tell me the area of his skill. To make it more interesting, you must just print n bits after decimal point.

    Input

    The input file will contain several tests,it will end with EOF, each test contain two integers L and n .(0<=L<=25,0<=n<=6)

    Output

    Your answer .Please notice that when your answer is 0, as you can see 0 is the same to 0.0 or 0.00 or 0.000 ……, so you should just print 0. And when the n is 0, you should not print decimal point.

    Sample Input

    1 0
    1 1
    1 4
    

    Sample Output

    3
    3.1
    3.1415 


    题意:

    求圆的面积,并控制小数点后输出位数。

    因为.nf没办法实时控制那个n,所以只能分类讨论n的值。并且这题要注意.f格式的自动四舍五入问题,所以要对末位的更小的那一位进行是否<5的特判。

    注:以后坚决不会再用fixed<<setprecision(n)了...事实证明C++里面的控制格式输出符根本毫无卵用...还有那个hex之类的...都不要用了,没用的。
