About the FSTM

The University of Luxembourg is an international research university with a distinctly multilingual and interdisciplinary character.

The Faculty of Science, Technology and Medicine (FSTM) at the University of Luxembourg contributes multidisciplinary expertise in the fields of Mathematics, Physics, Engineering, Computer Science, Life Sciences and Medicine.
Through its dual mission of teaching and research, the FSTM seeks to generate and disseminate knowledge and train new generations of responsible citizens in order to better understand, explain and advance society and environment we live in.

Since 2006, the University of Luxembourg has invested in its own High-Performance Computing (HPC) facilities. Special focus was laid on developing large computing power combined with huge data storage capacity to accelerate the research performed in intensive computing and large-scale data analytics (Big Data).

To face the growing needs and new projects of the University of Luxembourg, the Digital Platforms team has been created to install, extend, operate and administrate the HPC platform, composed of 2 HPC clusters, Iris and Aion.
