DKRZ Tech Talk: Debugging parallel codes with DDT

Mar 16, 2021

Dear users,

It is our great pleasure to announce next week’s Tech Talk. On Tuesday, Mar 16 at 15:15, Suyash Sharma (ARM) and Florian Ziemen (DKRZ) will present the debugger DDT and its application to the ICON model on mistral.

Debugging parallel climate models can be a daunting task, but it becomes much easier once you can study the state of all model variables at the moment of the crash, or any other unexpected behavior. On Mistral, ARM DDT provides a user-friendly GUI for debugging simulations with up to 1000 MPI threads, and on Levante, we will keep providing DDT. In this Tech Talk, Suyash Sharma of ARM will introduce the basic concepts of using a debugger and demonstrate how DDT can provide insights into a real-world ICON crash.

Please register by taking the poll at https://terminplaner2.dfn.de/dkrz-tech-talk-debugging using your institutional e-mail address.
