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

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

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
• HPC Programming and Usage of the main softwares available on the platform (Mathlab, R, MPI etc.)
• Performance analysis, debugging & profiling
• Scientific visualization

The aim is to cover basic as well as advanced usage of the platform. Whether you are an HPC newbies or an advanced user, don’t miss this unique opportunity to learn more about the efficient usage of the system.

Program

All sessions will take place at the Kirchberg Campus, mainly in the Paul Feidert Room.

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.
The detailed program is available here.

Practical information

Location

The HPC school will be organized at the campus Kirchberg of the University of Luxembourg.

University of Luxembourg, campus Kirchberg
6, rue Richard Coudenhove - Kalergi,
L-1359, Luxembourg (Kirchberg)
49°37’34.3”N 6°09’30.9”E (49.626201, 6.158596)

• OpenStreetMap
• Google Maps

Transport

By bus, from the airport

Take the bus 16 (every 10/25 minutes), get off at stop Coudenhove-Kalergi

By bus, from the train station

Several choices:

• Bus 18 (every 8 minutes), get off at stop Université - Campus Kirchberg
• Bus 16, 192, 120, 1, get off at stop Coudenhove-Kalergi (after the Cocque, the sport center of the Kirchberg plateau).

More information: Mobilitait Zentral

By car

You can park your car on the campus, or more probably at the parking Adenauer

2014 Edition Feedback

Now that the HPC School 2014 took place, we are able to propose a first feedback.

• 66 participants registered (including 1 external and 1 SnT visitor) distributed as follows:

Institute	Number of persons	Percentage
FDEF (incl. 4 LSF)	7	10,61 %
FLSHASE	1	1,52 %
FSTC	29	43,94 %
LCSB	17	25,76 %
SnT (incl. 1 visitor)	8	12,12 %
Externals	1	1,52 %
Master Students	3	4,55 %
TOTAL:	66

A satisfactory form has been proposed to the participants for each day and the global feedback is very positive. We now seek a yearly event, and possibly a more frequent session targeting only new users.
