综上所述，superscalar、multithreading和multicore都是提高CPU性能的重要技术，但它们的作用方式和应用场景有所不同。superscalar侧重于指令层面的并行执行，multithreading和hyperthreading则侧重于任务层面的并行处理，而multicore则是从硬件层面提供多个独立的处理核心来同时处理不同的任务。
Hyper-Threading is an Intel® hardware innovation that allows multiple threads to run on each core, this means more work can be done in parallel.
让我们以高速公路收费站为比喻，深入理解superscalar、multithreading（顺便提及hyperthreading）和multi-core的区别。1. 一般情况设计者要为过往车辆收费，最简单的方法是让车辆按顺序过一个收费站。但若车流量大，效率会受限。为了提升速度，我们有几种策略：2. 多收费站就像高速公路增加多个收费点，多线程...
这里额外提一句hyperthreading,这个技术比较复杂而且实际表现也没有那么好(在intel顶级CPU上还在使用,追求极致效率),用比较模糊的话说就是把一个CPU核心掰成两半 (其实还是thread的优化),模拟出多个logical units,本质上是建立在multithreading中每个thread利用率不高的前提下进一步提高效率。 superscalar是risc的技术,需要...
Particularly we’ll introduce multithreading and hyperthreading techniques, talk about their different approach, highlight their advantages and disadvantages, and discuss their most frequent usage. 2. Multithreading In computer systems, processors execute lightweight sets of instructions that are called ...
·siblings—Displays the number of sibling CPUs on the same physical CPU for architectures which use hyper-threading. ·flags—Defines a number of different qualities about the processor, such as the presence of a floating point unit (FPU) and the ability to process MMX instructions. ...
The origin of hyperthreading How does hyperthreading technology work? How can hyperthreading be activated? What are the benefits of hyperthreading? Multi-core processors vs. virtual cores: which makes more sense? The difference between multithreading vs. hyperthreading Practical examples of the hyper...

Most CPU servers implement simultaneous multithreading (SMT) cores (e.g., Intel Hyper-Threading), which are seen as different logical CPUs by the OS. We study the impact of varying the number of threads or scalability, as well as the effect of Hyper-Threading (i.e., threads running on ...
