Founded in 1991, the University of Versailles Saint-Quentin-en-Yvelines (UVSQ) is located in Versailles and a major contributor to the creation of the University of Paris-Saclay, especially in the field of Computer Science. UVSQ is strongly involved in the field of High Performance Computing (HPC) through various research laboratories and industrial projects. The HPCNet team, first known as ARPA is part of the CNRS laboratory called PRiSM (Parallélisme Réseaux Systèmes et Modélisation); since the nineties, it is a specialist in the field of very High Performance Computing architectures, performance evaluation and optimisation tools, intensive numerical computation and advanced communication architectures.
In 2004, a joint research laboratory between UVSQ and CEA DAM was created, called LRC-ITACA and specialised in code optimisation and performance evaluation. This structure has been involved in many national, European and international research projects. In 2009, CEA, GENCI, Intel and UVSQ together founded the Exascale Computing Research (ECR) laboratory. The objective was to anticipate the challenges of future HPC architectures. ECR is operational since March 2010.
Specifically in the field of HPC, HPCNet team, LRC-ITACA and ECR have developed an ecosystem of tools allowing to analyse and provide fine level performance and energy optimisation of HPC applications. Different industrial and academic partnerships allowed to validate these tools on real code; our tool-chain allowed to speed up the Yales 2 solver at Coria or the strongly parallel application QMC= Chem at CNRS and University Paul Sabatier. Simultaneously, the performance analysis tool, MAQAO, has moved to the Vi-HPS initiative, a consortium that gathers the main European and international performance analysis tools.
