针对“普通级(以上)厨师”的高级计算机概念: 简介

之前在与一位非常聪明但不是专业工程师的同事交谈时,我发现有必要对线程化和英特尔® 至强融核™ ⅹ100 和 ⅹ200 架构的其他组件稍作解释。 首先关于超线程,(说的更具体一点)以及协处理器的超线程版本。 经过冥思苦想,我终于想到可以用公共厨房来进行恰当的比喻。

针对“普通级(以上)厨师”的高级计算机概念: 术语(第 1 部分)

开始之前,我想通过下面两篇博客解释一些术语。 如果对这些概念已经有所了解,可以直接跳至下一部分。  我建议所有软件读者参阅其他关于介绍线程的博客。 这个领域存在许多混淆,即使我们软件专业人员也无法避免。

我们首先来了解一下什么是处理器、CPU、内核以及封装。 电视等大众媒体在使用这些术语时通常比较随便。 然后我们介绍线程,尤其是硬件和软件线程之间的区别。 人们通常容易混淆这些不同线程之间的区别,即使计算机编程人员也不例外。

内核? CPU? 封装? 芯片? HUH?

请大家注意下图 CPU 的左侧。 在奔腾® 处理器时代,人们通常将计算机中执行程序指令的组件(即计算机的大脑)称为“CPU” 或‘处理器’。 这两者之间几乎没有区别。 ‘计算机芯片’指上面刻有集成电路的芯片,比如 CPU。 ‘封装’指由塑料和金属制成的外壳,用于包裹和保护芯片不被大量针脚/接口刺穿,同时也是出于美观的考虑。

Advanced Computer Concepts for The (Not So) Common Chef: First Some Terminology Part 2

OF COURSE, I KNOW WHAT A THREAD IS….DON’T I?

Now that we know what a core is, let’s dive into another source of confusion.

This section gets a little deeper into techno babble than I wanted for this series of blogs. If you are so inclined, my gourmet readers, you can either skip or read on. I believe the rest of the blogs can be understood with or without this little aside. But for those of you who are already familiar with threading, it may give you more insight than would be the case otherwise.

Advanced Computer Concepts For The (Not So) Common Chef: Terminology Pt 1

Before we start, I will use the next two blogs to clear up some terminology. If you are familiar with these concepts, I give you permission to jump to the next section.  I suggest any software readers still check out the other blog about threads. There is a lot of confusion, even among us software professionals.

Advanced Computer Concepts For The (Not So) Common Chef: Introduction

While talking to a very intelligent but non-engineer colleague, I found myself needing to explain the threading and other components of the current and next generation Intel® Xeon Phi™ architectures. The first topic that came up was hyper-threading, and more specifically, the coprocessor’s version of hyper-threading. Wracking my brain, I finally hit upon an analogy that seemed to suit: the common kitchen.

  • Submissions open: High Performance Parallelism Gems

    We have all had our little discoveries and triumphs in identifying new and innovative approaches that increased the performance of our applications. Occasionally we find something more, something that could also help others, an innovative gem. You now have an opportunity to broadcast your successes more widely to the benefit of our community. You are invited to submit a proposal to a contribution-based book, working title, “High Performance Parallelism Gems – Successful Approaches for Multicore and Many-core Programming” that will focus on practical techniques for Intel® Xeon® processor and Intel® Xeon Phi™ coprocessor parallel computing. Submissions are due by May 29, 2014.
