Olivier Sentieys

Short Biography

I am a Professor at the University of Rennes holding the Inria Research Chair on Energy-Efficient Computing Systems. I am leading the Taran team common to Inria (French National Institute for Research in Digital Science and Technology) and IRISA Laboratory. Until 2019, I was also the head of the “Computer Architecture” department of IRISA. From 2012 to 2017, I was on secondment at INRIA as a Senior Research Director. My research interests are in the area of computer architectures, computer arithmetic, embedded systems and signal processing, with a focus on system-level design, energy-efficient hardware accelerators (especially for machine learning and data mining), approximate computing (reduced-precision arithmetic, numerical accuracy analysis), and fault tolerance. I previously also worked on power management of energy harvesting sensor networks, signal processing for communications systems and low power wireless (body) sensor networks. I authored or co-authored more than 300 journal or conference papers, hold 6 patents, and served in the technical committees of several international IEEE/ACM/IFIP conferences, including DATE, ICCAD, FPL. I am currently serving in the DATE Executive Committee.

Acronyms

As we have many in the French Academic system... below a tentative explanation.

Irisa (Institut de Recherche en Informatique et Systèmes Aléatoires - Research Institute in Computer Science and Random Systems) is a joint research laboratory (UMR 6074) gathering more than 700 people (faculty members, PhD students, PostDoc, engineers, administrative and technical staff) from Inria, CNRS, University of Rennes (main partner), INSA Rennes and ENS Rennes.

Enssat (graduate engineering school in applied science and technologies) is a graduate engineering school of Univ. Rennes 1 located in Lannion.

Inria is the French science and technology research institute (3500 researchers) fully dedicated to computational sciences. Inria Rennes - Bretagne Atlantique is one of its eight research centers.

Cairn is the research group I lead (~50 people). The team is common to Irisa and Inria and includes (Nov. 2012): 13 faculty members from UR1, Inria, and CNRS; 28 PhD students; 5 Post-Docs; 8 research engineers; 3 associated members.

The scientific aim of Cairn is to study reconfigurable system-on-chip, i.e. hardware systems whose configuration may change before or even during execution, from three angles: the invention of new reconfigurable platforms, the development of associated compilation and synthesis tools, and the exploration of the interaction between algorithms and architectures.
