HPC @ Uni.lu

High Performance Computing in Luxembourg

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 will offer instructions and practical sessions with the aim to cover the basic usage of the platform for newcomers, on the following topics:

  • Accessing and interacting with the UL HPC infrastructure
  • HPC challenges, especially as regards data and storage management
  • HPC workflow management
  • Software environment deployment

New members of the UL or HPC beginners should not miss this opportunity to learn about the efficient usage of the HPC platform.

This edition of the UL HPC School for beginners will take place on:
March 13th, 2015, on the Kirchberg campus, in B13 (morning) and A02 (afternoon)


The sessions will take place at the Kirchberg Campus, in B13 and A02.

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

All tutorials proposed as practical sessions are available on GitHub.
