Content levels

Beginners: 10 hours
Intermediate: 10 hours

Prerequisites

Linux Course participants possess advanced basic knowledge of the free operating system Linux and knowledge of Linux applications. The background of Linux as well as the most important concepts and tools of Linux such as

Shell and shell commands (→confident use of the command line),
Secure Shell,
Working with files and scripts,
System structure,
User and permissions management, and
Creating simple batch scripts with an editor like nano, vi, or emacs should be familiar. Instructions for working on the training cluster will be provided. If you identify deficiencies in this area, we refer you to https://www.tuxcademy.org/product/lxes/

Programming Skills

You have solid programming skills in a programming language (C / C++ or Fortran).
You can understand additional programming languages and their constructs.
You are able to work with compilers and linkers.
You have knowledge of makefiles and can create them.

Basic Hardware Understanding Participants understand how the hardware of a classic computer is structured. This includes primarily a basic understanding of

Processors (CPU),
Random access memory (RAM),
Connection between these two components,
Networking technology,
Hard drives, and
Hardware accelerators.

Technical requirement

Computer with a SSH protocol.
- Software may need to be installed. You must have the necessary permissions to do so.
- Network connections to external clusters must be possible.
Alternatively to SSH, you can also use your own PC and a modern compiler that supports OpenMP 5.0, see the OpenMP website for a comprehensive list openmp-compilers-tools.
A stable internet connection is recommended for working through the learning materials and exercises.
Access to the video conferencing tool Webex with camera and microphone (a headset is recommended for audio quality).

Learning duration

Total time requirement is approximately 20 hours over a 2-week period (about 10 hours per week). Participants can schedule their time flexibly each week, except for mandatory virtual seminars (held in the evenings) and the exam (held during the day).

HLRS concept for flexible learning

Flexible learning

This course offers flexible learning, allowing you to learn at your own pace and access online course materials and cluster resources. Web-seminars are held weekly to discuss the learning modules and to answer your questions. We also provide forum channels that enable you to communicate with the lecturer and peers, as well as to share your experiences.

Learning duration

The course is divided into multiple learning units of 10 hours each. Participants can learn the individual learning content on their own schedule. In addition, this course has fixed dates for virtual seminars and the exam.

Course certificate & confirmation of participation

The High-Performance Computing Center (HLRS) issues participants a confirmation of participation if they have joined all seminars and hand in at least 50% of the assignments, as well as a course certificate if they have passed the exam at the end of the course.

Technical requirement

Stable Internet connection so you can access and download the learning materials.
Access to video conferencing tool with camera and microphone for participation in regular seminars.
