machine specific 系统设置
Antipattern: Some may use a different deployment script for each target environment or even for a specific machine.
反模式:一些团队为每个目标环境(甚至特定的计算机)使用不同的部署脚本。
For this article, I'll focus on three specific machine-learning tasks that Mahout currently implements. They also happen to be three areas that are quite commonly used in real applications.
在本文中,我将重点讨论Mahout当前已实现的三个具体的机器学习任务。
Code selection is an important task in code generation, where the goal is to find an efficient mapping of machine-independent intermediate code to processor-specific machine instructions.
代码选择在编译器的代码产生阶段是一个十分重要的任务,它的目标就是在与机器无关的中间表示代码和与处理器相关的机器指令之间寻找一种高效的映射方法。
But because we're now programming a computer at a lower level and because as we said last week, you really have to be precise and then careful to instruct this machine, this fairly dumb machine that will only do what you tell it to do very specific instructions, do we have to use a more precise syntax than just a puzzle piece might have previously allowed.
但是我们是要在电脑的低平台上编程不是吗?,那我们就要像我上周提到过的那样,一定要小心,小心,再小心地,操纵这台又聋又哑的机器,它只会根据你敲进去的,特定指令来做事,所以我们必须使用非常精细的语法,而不是模模糊糊,让人费解的概念。
