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 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, BigData tools) and services using the platform
  • Software environment management
  • Virtualization on the clusters

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.

Important Pre-registration is required. No on-site registration will be accepted. Pre-registration will be accepted until Friday, June 9th, 2017. Registration Fees (200€) applies for UL externals and should be paid prior to the venue.

This fifth edition of the UL HPC School will take place on:
June 12th and 13th, 2017, on the Belval campus, Location: MSA 4th Floor, rooms 4.510 and 4.520
