Introduction
Totalview is a widely used debugger in the field of HPC. This video series provides an introduction to debugging techniques and methodology, and a practical hands-on tutorial to the Totalview debugger.
This tutorial is targeted for software developers as an initial introduction to debugging with Totalview.
How to proceed through this tutorial?
The tutorial is currently made of 5 segments, each detailing on basic debugging techniques. Additional segments, will be added as they are produced. Each video segment uses practical examples, provided as source files, that can be followed along. Access to the Totalview debugger is recommended to follow the tutorial along.
Who created this tutorial?
This tutorial has been developed by the Competence Center for High Performance Computing in Hessen (HKHLR).
The speaker is Dr. Christian Iwainsky from Technische Universiät Darmstadt. Christian works at the university's IT center. The slide are a collective effort of the HKHLR, and video editing was done by himself, with support by Laurin Eisenacher in editing the audio.
Videos
Each video builds on the previous videos. It is recommended to watch all videos in sequence.
Video 1: Introduction to debugging and Totalview
This video provides a brief overview of the debugging process and mindset and then introduces the debugger Totalview.
