Supercomputing 2019

Numerical simulation, massive data processing and AI enabled and boosted by HPC have become an indispensable tool for technology and research progress.

As a European HPC leader, this was the opportunity for CEA to showcase its experience and involvement in HPC, Big Data and AI from technological research and development to applications, and to highlight the pivotal role of its supercomputing facilities.

HPCwire Editor’s Choice award in the area of Best Use of HPC in Life Sciences granted to a CEA team

A research team led by Dr. Luc Bergé (Research Director at CEA) got his award. CAPITOL project used compute hours allocated by PRACE (24.1 million hours on CURIE machine hosted and operated at CEA TGCC, made available by GENCi). The objective was to explore new physical mechanisms for the conversion of ultra-intense laser light into various photon and particle sources, from THz to X-rays, via laser-plasma interactions. Several massively parallel numerical codes were used for this purpose. The study could lead to a breakthrough in high-resolution medical imaging for breast and skin cancer tumors detection.

Seminar INHP@CT:

Driven Development philosophy and 9 years usage feedback for research in HPC

Sébastien VALAT, Engineer at ATOS/BULL.

"Nowadays HPC systems still continue growing and offer capabilities to handle more and more complex simulations. It goes with a large increase in complexity to be managed by the engineers and researchers who develop the software stack. Test Driven Development (TDD) is a well-known technic in many fields now, more on the Java, python and web world. On the HPC side, this is not so often used or known for many reasons: legacy codes/languages, research developments, not trained developers.... "

Inauguration of Joliot-Curie, the French supercomputer dedicated to French and European research

At 9.4 petaflops, Joliot-Curie is France’s third supercomputer and is set to become the most powerful French research supercomputer in 2020 when it reaches 22 petaflops. Designed by the European leader in supercomputing, Atos, for the French national high-performance computing organisation (GENCI), this new supercomputer located at the CEA’s Very Large Computing Centre (TGCC) was inaugurated on 3 June 2019 by François Jacq, CEA Chairman, Thierry Breton, Atos CEO, and Philippe Lavocat, GENCI CEO.

    Better understanding of the climate system through digital simulation
    News release

    French scientists offer strong contribution to coordinated international effort to better understand the climate system through computer simulations.

    Climate scientists at the Institut Pierre Simon Laplace (IPSL) and CNRM-CERFACS announce today the release of new datasets that promise to provide fresh insights into past and future climate change. IPSL and CNRM-CERFACS are engaged, with other climate research centres, in an international effort to provide a new generation of climate change experiments.

    Seminar INHP@CT:

    Programming for In-Memory Computing

    Maha Kooli, researcher at the Laboratory of Computer Science, Robotics and Microelectronics of Montpellier, will present his work on PProgramming In-Memory.


    In-Memory Computing (IMC) corresponds to a new data computation concept that brings the computing operations inside the memory units. It has been introduced to overcome the von Neumann bottleneck in terms of data transfer rate and power consumption.
    A new IMC system based on SRAM architecture is introduced. It permits performing logic operations (and, or, xor, etc), arithmetic operations (addition, subtraction, etc), and memory operations (set, reset, write, etc). IMC system permits highly parallel computation inside the memory.
    At the current research stage, the circuit-level design of the IMC system has not been completed yet. We therefore introduce a dedicated software platform based on LLVM that includes emulation tools to early experiment and evaluate how applications can take advantage of the IMC system. We evaluate the execution time and the energy consumption and we compare to conventional CPU-based systems. We target different application scenarios in various fields (image processing, cryptography, intensive computation).
