A joint event of the DKRZ user group and the natESM project will be held to share experiences in adapting to new conditions in HPC in general and using the new HLRE-4 system to address the research questions in particular.
This on-site meeting at DKRZ is filled with talks reflecting the diversity of climate models simulated at DKRZ and dealing with ML in climate research. However, there will also be explicit room for a lively exchange between users on the following topics:

- How to make use of GPUs?
- How can ML support ESM?
- How to organize data in the modeling workflow?
- Quo vadis climate modelling - capability vs capacity computing?

The first day will conclude with an evening poster session with the opportunity for the presentation of previous research results and further exchange on current and upcoming topics.

On the second day two parallel training courses with explicit hands-on are offered:
1. natESM:
The natESM Support Team offers trainings sessions for the natESM community. Three key points are: GPUS and how to port, profiling and tracing tools and an extensive hands-on session about profiling applications on Levante for natESM support requests in the on-going project.
2. Data Management:
The Data Management Training Session focuses on the services offered at DKRZ to make your life as climate scientists using DKRZ resources easier (in terms of data handling). Several topics will be addressed with a focus on hands-on experience: Introduction to Data Management Planning, Data Standardization, large-volume datasets hosted at DKRZ using catalogs, overview about WDCC and DOKU, DKRZ tape archive (StrongLink) and hands-on FREVA.

There will also be an opportunity for networking. Please let us know in advance if you would like to organize a side meeting for your community for room planning.

We ask for registration until 30 September - after that we cannot guarantee participation.

Parallel discussion sessions "World-Cafe"

In 4 different rooms the mentioned topics will be discussed together and changed after a certain time - so that every participant gets insights to all topics.

  • Quo vadis climate modelling - capability vs capacity computing?Moderator: Prof. Dr. Daniela Jacob, GERICS

  • How to make use of GPUs?Moderator: Dr. Panagiotis Adamidis, DKRZ and Dr. Claudia Frauen, DKRZ

  • How can ML support ESM? Where is the point of best usage?Moderator: Dr. Christopher Kadow, DKRZ

  • How to organize data in the modeling workflow?Current and upcoming challenges in all aspects of data management. Moderator: Dr. Andrea Lammert, DKRZ

18:00 – 21:00

Poster Session and Ice Breaker

13 October 2022

  9:00 – 11:00

Parallel sessions: Lectures

1) 09:00 – 10:00 CUDA, OpenACC, and more: Many ways lead to GPUs, Andreas Herten, JSC
2) 10:00 – 11:00 Performance analysis in a nutshell, Michael Knobloch, JSC

11:00 – 11:30

Coffee Break

11:30 – 13:00

Parallel sessions: Hands-on I: CUDA, OpenACC, and more:

Many ways lead to GPUsIn this session, we will focus on utilizing GPUs for scientific workloads. First, in form of a talk, the most important features of massively parallel GPU architectures are outlined and different programming models presented. Then, in a subsequent hands-on session, practical examples of porting to these programming models are given, focussing on the most commonly used models (CUDA, OpenACC, possibly Kokkos).

13:00 – 14:00

Lunch

14:00 - 16:00

Parallel sessions: Hands-on II natESM:Performance analysis in a nutshell

Performance analysis is an integral part in the HPC workflow to understand the execution behavior of an application on a specific system and to identify optimization opportunities.In this workshop the participants will learn about the Score-P measurement system and the associated analysis tools Cube, Vampir, and Scalasca. In a hands-on part the participants will get practical knowledge applying the tools on a small benchmark code, enabling them to use the tools with their application later on.
