限时删除!!

这是我的一本CS教科书中的一个问题.我很茫然.我不明白为什么它一定会导致并行计算.有人想指出我正确的方向吗?

This was a question in one of my CS textbooks. I am at a loss. I don't see why it necessarily would lead to parallel computing. Anyone wanna point me in the right direction?

推荐答案

摩尔定律只是说,价格合理的集成电路上的晶体管数量往往每两年增加一倍.

Moore's law just says that the number of transistors on a reasonably priced integrated circuit tends to double every 2 years.

关于速度,晶体管密度或芯片尺寸的观察都与原始观察结果有些正交.

Observations about speed or transistor density or die size are all somewhat orthogonal to the original observation.

这就是为什么我认为摩尔定律不可避免地导致并行计算的原因:

Here's why I think Moore's law leads inevitably to parallel computing:

如果您将晶体管的数量增加一倍,您将如何处理它们?

If you keep doubling the number of transistors, what are you going to do with them all?

  • 更多说明!
  • 更广泛的数据类型!
  • 浮点数学!
  • 更多缓存(L1,L2,L3)!
  • 微型行动!
  • 更多的管道阶段!
  • 分支预测!
  • 投机执行!
  • 数据预取!
  • 单指令多数据!
  • More instructions!
  • Wider data types!
  • Floating Point Math!
  • More caches (L1, L2, L3)!
  • Micro Ops!
  • More pipeline stages!
  • Branch prediction!
  • Speculative execution!
  • Data Pre-Fetch!
  • Single Instruction Multiple Data!

最终,当您实现了所有可以想到的使用所有这些额外晶体管的技巧时,您最终都会对自己进行思考:为什么我们不对随附芯片上的所有这些很棒的技巧进行两次TWICE?

Eventually, when you've implemented all the tricks you can think of to use all those extra transistors, you eventually think to yourself: why don't we just do all those cool tricks TWICE on the came chip?

八大兵.八大繁荣.多核是不可避免的.

Bada bing. Bada boom. Multicore is inevitable.

顺便说一句,我认为具有多个相同CPU内核的CPU的当前趋势也将最终消退,未来的实际处理器将具有单个主内核,一组通用内核和一组专用内核.协处理器(如图形卡,但与CPU和缓存一起使用).

Incidentally, I think the current trend of CPUs with multiple identical CPU cores will eventually subside as well, and the real processors of the future will have a single master core, a collection of general purpose cores, and a collection of special purpose coprocessors (like a graphics card, but on-die with the CPU and caches).

IBM Cell处理器(在PS3中)已经有点像这样.它具有一个主核心和七个协同处理单元".

The IBM Cell processor (in the PS3) is already somewhat like this. It has one master core and seven "synergistic processing units".
