CEA (Commissariat à l’énergie atomique et aux énergies alternatives) is a government-funded research organisation, focusing on low-carbon energies, defense and security, information technologies and health technologies, and fundamental research. CEA-DRT-LETI (Laboratory for Electronics & Information Technology) aims at helping companies to increase their competitiveness through technological innovation and transfer of its technical know-how to industry. With 8000 m² SOA clean rooms, some 160 M€ of equipments, 1600 people and a very important patents portfolio, CEA-DRT-LETI has 5 program-oriented departments: microelectronics, microsystems, optronics, system design, and technologies for bio and health. The Design Architectures & Embedded Software Division (DACLE division), common to CEA-DRT-LETI and CEA-DRT-LIST, gathers more than 200 people focusing, among others, on digital and SoC, design for high performance and embedded systems, and embedded software. It provides expertise in advanced computing architecture and highly integrated system design, highly integrated/massively parallel processors, computing architecture for future technologies, programming, compilation and execution environments for low-power applications, feedback-control for cost, variability and energy consumption reduction.

Contribution to OPRECOMP

CEA will contribute in WP5 with a software controller framework that adapts an algorithm’s accuracy at run-time, depending on execution conditions, and fabrication technology, i.e., FDSOI characteristics. CEA will also coordinate the demonstration activities in WP8.

Henri-Pierre Charles

Research Director at CEA-LIST

Henri-Pierre Charles is research director at CEA-LIST since September 2010. He was previously assistant professor in Versailles University during 17 years, authorised to supervise PhD students (HDR) since 2008. During this period he participated in many European and national projects, mainly in the high performance computing domain. He has supervised many PhD theses on code optimisations and High performance computing. Since his arrival in CEA he applied his knowledge on multi-processor system on chip (MPSoC) and embedded systems.
His research interests are in dynamic compilation, Low level code optimisation and new methods for code generation for high performances and multimedia applications. He has developed the concept of “compilettes” that can be defined as tiny code generators embedded into applications, able to generate optimal code depending on the data characteristics.
He’s involved in the OPRECOMP project as a work package leader and main CEA contact.

Yves Durand

Research Director at CEA-LIST

He received his engineering degree in 1983 and a PhD in computer science in 1988. He worked with ST Microelectronics as a research engineer, then moved to Hewlett Packard in 1993 and led R&D projects related to networking interfaces and « smart communicating objects ». He joined the Laboratoire d’Electronique et de Technologie de l’Information (CEA-LETI), Grenoble, in 2003. He has been coordinating the IST FP6 4More project. His current focus is numerical modeling of computing systems.
He is involved in OPRECOMP for the design and modeling of approximate computing units for embedded devices.

Anca Molnos

She received her M.Sc. degree in computer science from the “Politehnica” University of Bucharest, Romania and the Ph.D. degree in computer engineering from the Delft University of Technology, The Netherlands, in 2001 and 2009, respectively. Between 2006 and 2009 she was senior scientist at NXP Semiconductors, The Netherlands, working on low-power multi-processors and distributed real-time systems. From 2009 to 2012 she was a researcher with the Delft University of Technology, working on embedded multi-core resource management for low-power and quality of service. In 2013 she joined CEA LETI, where her research focuses on developing energy-aware software, energy and variability management, and frameworks for adaptable parallel systems. She is the scientific coordinator of French-Swiss joint national project Artefact (AppRoximaTivE Flexible Circuits and Computing for IoT).

David Coriat

He received his M.Sc. degree for the University of Science of Montpellier, France, in 2012, and subsequently joined the CEA-LETI Minatec. He has worked on dynamic management of power and variability in MP-SoC architectures as well as power estimation techniques in large MP-SoC architectures. His research interests now lie in low power architectures and transprecision computing at hardware level.

For the OPRECOMP project, he’s involved in hardware architecture and in transprecision units implementation.
