Conference from - @ Grundlsee (username: ashpc22-user, password: conferenceuser) -  Abstracts - PDF


Update from VSC

  • Next generation Vienna Scientific Cluster (VSC5) will be fully available in Summer 2022. 20 GPU-Nodes are still missing.
  • 710 CPU-Nodes
    • 570 Nodes (512 GB)
    • 120 Nodes (1 TB)
    • 20 Nodes (2 TB)
  • 60 GPU-Nodes
    • 512 GB
    • 2x NVIDIA A100
  • AMD Epyc 7713 (4 NUMA, Cores: 64, Threads: 128, BaseClock 2.0 GHz, L3 Cache: 256 MB)
    • INTEL compilers are still a good option for FORTRAN.
  • Actually #301 in the Top500-List (95,232 Cores, 3.05 PFlops/s, 516 kW, e.g. VSC4-#82 (2019))
  • we requested more storage for IMGW:  100TB in DATA.
    • more storage will cause fees
  • New JupyterHub + NoMachine (GUI, 4 Workstations)
  • provide support for application rewriting/optimizing 
  • upcoming Future-Plan: connect Storage-System of JET to VSC


talk by Vangelis Floros from EuroHPC JU

Euro-HPC: a legal and funding entity created in 2018 with headquarters in Luxembourg. Bundle HPC in Europe. follows PRACE.

NCC - Austria 

talk by Sarah Stryeck

A National Competence Center for High-Performance Computing, High-Performance Data Analytics and Artificial Intelligence.

(question) What to use EuroHPC Resources? They advise and help with proposals!

Contact: /

Note: Support for Software-Development can be provided directly from the EuroHPC-Centers (some showcases).

Tips and tricks from the user perspective with PRACE/EuroHPC applications

talk by Philipp Gschwandtner from University of Innsbruck

Motivation for proposals:

  • PRACE/EuroHPC proposals are considerable effort, but high pay-off
  • not as difficult as might think → PRACE acceptance rates are quite high
  • Ingredients for a successful PRACE/EuroHPC access proposal
    1. Scientific Problem + Solution
    2. Fast and scale-able implementation
    3. A pinch of luck
    4. Let it simmer for a few weeks
    5. Enjoy!
  • WE can ask him for SUPPORT / ADVISE too


One awarded project was kmMountains: a structured grid simulation of climate change in mountainous landscapes (Alps, Himalaya)
