High Performance Computing in Luxembourg

This website is deprecated, the old pages are kept online but you should refer in priority to the new web site hpc.uni.lu and the new technical documentation site hpc-docs.uni.lu

The University of Luxembourg operates since 2007 a High Performance Computing platform which currently features a total of nodes (in practice, computing cores) for a cumulative computing power estimated at TFlops.

The total raw storage capacity shared within the clusters is currently estimated at TB (NFS + Lustre).

The effective usage of this complex platform is not an easy task and requires both talent and system skills to understand the impact of our personal workflow on the global performance of the system.

The UL HPC management team, together with leading computational scientists of the UL and HPC technologists will offer instructions and practical sessions on a variety of topics, including:

  • Access to and interaction with the UL HPC infrastructures
  • HPC challenges, especially as regards data and storage management
  • HPC workflow management (for sequential and parallel tasks)
  • HPC Programming and Usage of the main software available on the platform (Matlab, R, MPI, physics, chemistry, bioinformatics tools) and services (Galaxy) using the platform
  • Scientific visualization
  • Software environment management
  • Virtualization on the clusters linked to the Grid’5000 platform

The aim is to cover basic as well as advanced usage of the platform. Whether you have no HPC experience or are an advanced user, don’t miss this unique opportunity to learn more about the efficient usage of the system.

This third edition of the UL HPC School took place on:
June 25th and 26th, 2015, on the Limpertsberg campus, the “BS 3.03 Auditorium (Sciences Building)”

Program

All sessions will take place at the Limpertsberg Campus, with the main track in the BS 3.03 Auditorium.

Important You are expected to bring your laptop for all sessions since there will be no workstation available on site.

All tutorials proposed as practical sessions will be available on GitHub. The detailed program is available here.
