HPC Wiki

Welcome to the HPC Wiki the source for site-independent High Performance Computing Information.

<<-- On the left hand there are different target groups with their respective material.

Target Groups

- Basics: Covering the basics for users with not prior HPC experience.

- HPC-User: Covering topics for users of existing HPC software on HPC systems, including batch systems and third-party simulation software.

- HPC-Developer: Covering topics for users developing HPC software on HPC systems, including programming paradigms, compilers and runtime systems.

- HPC-Admin: Covering topics for administrators of HPC systems.

Categories

Getting_Started is a basic guide for first-time users. It covers a wide range of topics from access and login to system-independant concepts of Unix systems to data transfers. All articles in the Basics Section are written for inexperienced users and explain concepts in an easy-to-understand way.

Similar articles in the Users and Developer Section are planned, but not yet finished.

Look into the FAQs to see tips and instructions on How-to-Contribute to this wiki.
