Workshop: Hyperconnectivity for European HPC Supercomputers – Feedback from HPC users and providers

Description

The workshop “Hyperconnectivity for European HPC Supercomputers – Feedback from HPC users and providers” took place on 22 November 2023  from 10:00 – 15:00 (CET).

You may find the Workshop presentations further below.

The workshop took place as part of the EuroHPC JU study called EuroHyPerCon which kicked off in October 2023 and is very relevant to HPC providers, users, and the EuroHPC ecosystem. The main scope of the EuroHyPerCon project is to identify and analyse the connectivity requirements of HPC systems in Europe and subsequently specify a future-proof connectivity service, along with its implementation roadmap. The study is a crucial cornerstone for the EuroHPC JU to develop further and improve the European HPC ecosystem, and thus, the engagement of the HPC user community to provide feedback and connectivity requirements is vital. For this reason, European and national/regional HPC and data centres (essentially Tier-0 and Tier-1 systems), as well as the user communities behind them, are essential stakeholders in delivering requirements.

The workshop mainly focused on the feedback from HPC users and providers through panel discussions and breakout sessions.

We kindly ask you to forward the information about the study to additional stakeholders that you deem relevant.

Panel Discussion: HPC connectivity needs: Current State and Future Vision
11:00 - 12:30

Panel discussion with large-scale HPC users and HPC providers:

Moderators: Alexander Hektor, HLRS and Vassilis Merekoulias, Enomix

  • Users
    • Castiel2 Centres of Excellence, HIDALGO2, Marcin Lawenda, PSNC, Poland
    • Destination Earth, Thomas Geenen, ECMWF
    • IT4Innovations National Supercomputing Centre, Tomas Karasek, Czechia
    • SLICES ESFRI Research Infrastructure, Nikos Makris, University of Thessaly, Greece
  • Providers
    • Cyfronet, Marta Maj, Poland
    • Jülich Supercomputing Centre, Benedikt von St. Vieth, Germany
    • Karolina EuroHPC supercomputer and future LUMI-Q quantum computer, Branislav Jansík

The Session includes:

  • Short opening statement from each panelist
  • Discussion: Addressing current challenges and potential future directions in HPC connectivity needs.
    • Two main parts: Present and Future
      • Are there currently any bottlenecks in accessing the HPC providers? E.g. last mile, inside the origin user LAN or destination HPC center LAN, I/O storage rate
      • What about the future? Do you foresee any changes in the HPC ecosystem architecture? E.g. running jobs across multiple HPC centres.
      • How do you foresee the evolution of the relevant network infrastructure?
Lunch Break
12:30 - 13:15
Presentation of Questionnaires
13:15 - 13:35
