Computing centers / TGCC

Très Grand Centre de calcul

du CEA


TGCC is an infrastructure for scientific high-performance computing and Big Data, able to host petascale supercomputers.

This supercomputing center has been planned to welcome the first French Petascale machine Curie, funded by GENCI for the PRACE Research Infrastructure, and the next generation of Computing Center for Research and Technology (CCRT).
New Joliot-Curie supercomputer will replace Curie in the summer of 2018.



This new infrastructure is designed to:

  • accommodate future high end computing systems,

  • provide a communication and exhibition space for scientific events (conferences, seminars...),

  • propose a flexible and modular facility for future evolutions of HPC systems.

  • The infrastructure has been designed to optimize operating costs and power consumption.

    Designed by the company BULL and operated by teams of the very large computing center of CEA (TGCC) at Bruyères-le-Chatel, this supercomputer is one of the ten most powerful machines in the world.

    With over 92,000 computer units, for a power of 2 petaflops (or 2 million billion operations per second), Curie offers an exceptional tool for French and European scientific community.
    Curie was designed for Genci, a civil society in charge of the national HPC policy for academic research.
