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 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)
  • Prototyping with Python and Matlab in an HPC environment
  • Parallel debugging, profiling and performance analysis

The aim is to cover basic and intermediate-level usage of the platform, Whether you have no HPC experience or are an advanced user looking to refresh and update your knowledge, don’t miss this unique opportunity to learn more about the efficient usage of the system.

Important Pre-registration is required. No on-site registration will be accepted. Pre-registration will be accepted until 10am Tuesday, November 10th, 2017. Registration Fees (100€) applies for UL externals and should be paid prior to the venue.

This sixth edition of the UL HPC School will take place on:
Thursday, November 9th, 2017, on the Belval campus, Location: MSA 3rd floor, rooms 3.070 and 3.100

Program

All sessions will take place at the Belval Campus.

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.
