The Lichtenberg 2 Cluster at TU Darmstadt is a high-performance computer of the medium performance class (Tier-2). It has a heterogeneous architecture including large-memory nodes, accelerator systems with dedicated NVIDIA GP-GPUs, and several DGX A100 systems to support modern AI research.
The cluster is open to scientists from all universities and public research institutions in Germany. Computing resources are granted through a science-led allocation process.
Once a month, we offer an introduction to the use of the cluster. Now this introduction is also available as an online tutorial that can be accessed at any time.
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 on the Totalview debugger.
This tutorial is targeted for software developers as an initial introduction to debugging with Totalview.
The tutorial is currently made of 5 segments, each detailing on basic debugging techniques. 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.
Each video builds on the previous videos. It is recommended to watch all videos in sequence.
