Main Page

NOTE: This site is under constant development and is still in the very early days of it's existence!

Welcome to the general SNIC knowledge base and documentation site.

The aim of this site is that you should be able to get information, help, tips-and-tricks, etc. regarding the most widely used computational tools and scientific applications. The site also aims to provide general documentation related to the SNIC HPC-centers and various SNIC initiatives.

Discussion pages:
All pages on this site have parallel discussion pages (follow the link Discussion in the top of each page) where anyone interested can discuss the original page; add comments, suggestions, their own tips, new links etc. All you need to do to be able to edit a discussion page is to create an account for this wiki (Log in / create account). Creating an account only requires that you register a working e-mail address. Once you have an account, you can log in by following the link in the top right-hand corner of any page.

We strongly encourage all users to add comments etc. to the discussion pages, so we can improve the knowledge base and keep the provided information as fresh as possible.
