ARM’s Scalable Vector Extensions: A Critical Look at SVE2 For Integer Workloads

Scalable Vector Extensions (SVE) is ARM’s latest SIMD extension to their instruction set, which was announced back in 2016. A follow-up SVE2 extension was announced in 2019, designed to incorporate all functionality from ARM’s current primary SIMD extension, NEON (aka ASIMD).

Despite being announced 5 years ago, there is currently no generally available CPU which supports any form of SVE (which excludes the [Fugaku supercomputer](https://www.fujitsu.com/global/about/innovation/

I wanted to build an LDAP server that queries a MySQL server to fetch users and check their passwords. It is mainly used for old software that does not work with custom OAuth2 providers. Redmine is an example of this.

• ldapjs: library to start-off LDAP servers from scratch
• node.js driver for mysql: to connect to a mysql server

Instructions:

1. Create the database and table with insert.sql

相信很多人和我一样，拿到小米路由玩了几天，感觉官方的步伐不够快不够激进。既然如此，何不自己动手丰衣足食呢？

背景知识

首先你得知道Linux的一些基本理论，比如什么是bash啊，cd、ls这些命令怎么用等等。

其次你还得知道一些编程相关的东西，因为文章专注于Node.js的编译，所以Node.js和C++的一些基本知识是要有的。

热身准备
