High-Performance Matrix Multiplication

This is a short post that explains how to write a high-performance matrix multiplication program on modern processors. In this tutorial I will use a single core of the Skylake-client CPU with AVX2, but the principles in this post also apply to other processors with different instruction sets (such as AVX512).

Intro

Matrix multiplication is a mathematical operation that defines the product of

##Fixing npm permissions

You may receive an EACCES error when you try to install a package globally. This indicates that you do not have permission to write to the directories that npm uses to store global packages and commands.

You can fix this problem using one of three options:

Change the permission to npm's default directory. Change npm's default directory to another directory. Install Node with a package manager that takes care of this for you. You should back-up your computer before moving forward.

How to automatically deploy code to a server using Travis CI
View auto-deploying.md

Auto-Deploying via Travis CI

Because Travis CI can automatically execute scripts after successfully (or unsuccessfully!) executing tests, it is an obvious choice for a deployment tool. In order to deploy to a Git repository on a remote server, the process generally is as follows:

  • Set up SSH keys
  • Add the server's copy of the repository as a Git remote
  • Push to the remote
  • SSH into the server and execute any installation/compilation/miscellaneous commands

Before even touching .travis.yml...

Cheat Sheets are greate but they are not a substitute for learning the framework and reading the documentation as we most certainly have not covered every potential example here. Please refer to the Rails Command Line Docs for more information.

Command Line Generator Info

Reference

You can get all of this information on the command line.

rails generate with no generator name will output a list of all available generators and some information about global options. rails generate GENERATOR --help will list the options that can be passed to the specified generator.
