HoW exciting! 2022

Duration of the project

01.06.2022. - 24.06.2022.

Countries and institutions involved in the project

University of Latvia
Humboldt University of Berlin

Project manager

Prof. Dr. Andris Guļāns

Aims of the project

The event will take place on June 15-21 at LU. It will bring together young scientists and established experts from 6 universities (LU, HU, Université catholique de Louvain, TU Wien, Aalto University, and TU Dresden) and three supercomputing centres (Forschungszentrum Jülich, CSCS Switzerland, Barcelona Supercomputing Centre). The event will consist of a hackathon (including presentations and brainstorming sessions) and one-day hands-on tutorial. The goals of the event:

  • to enhance the collaboration between the participants,
  • to make progress in the development of high-performance computing (exascale) algorithms in electronic structure codes (exciting, Abinit and FHI-aims),
  • to transfer expertise in high-performance computing to local researchers.


The hackathon part will contain introductory talks and reports by Claudia Draxl (HU), Xavier Gonze (Université catholique de Louvain, Belgium), Alex Buccheri (HU), Maryam Azizi (Université catholique de Louvain, Belgium), and Andreas Grüneis (TU Wien).

The one-day tutorial will be given by Brian Wylie from the Forschungszentrum Jülich, Germany.


Hosting this event at LU will

  • provide an opportunity for young researchers (local and visiting) to interact with foreign peers and world-leading experts of this field,
  • make LU more recognizable as a research university,

strengthen collaboration between the participants of the event including the research groups lead by Prof. Draxl and Prof. Guļāns at HU and LU, respectively.

Main activities of the project

  1. Talks, work planning and coding assignments.

Venue: House of Science, LU, Riga.

Dates (including preparations): 10.05.2022-10.07.2022

Dates of the event itself: 15.06.2022-21.06.2022

  1. Hands-on tutorial: Performance analysis tools for applications in high-performance computing. Lectures and hands-on sessions.

Venue: House of Science, LU, Riga.

Dates (including preparations): 10.05.2022-10.07.2022

Dates of the event itself: 21.06.2022

Target group of the project


  • 20 hackathon participants – junior and senior researchers alike,
  • 5-10 participants at the hands-on tutorial.


The software solutions based on the outcome of this event will be implemented in the community codes developed by the participants and thus will serve their groups and later on also the international community consisting of hundreds of researchers worldwide. We estimate the number of people benefiting from the project as 200 researchers.
