ETH Zurich / CSCS

Swiss Federal Institute of Technology Zurich / Swiss National Supercomputing Centre

CSCS is a non for profit organisational unit of ETH Zurich. Its mission is to operate and provide scientists in Swiss research institutions with the computing resources as well as expertise in computer science, Visualization and Data Analysis they require to achieve their scientific goals.

 

CSCS is an equal opportunity employer and provides a very international and inclusive working environment. With around 40 employees representing over 13 different nationalities our working language is English although the local language is Italian. Thanks to the small size of the operation there is strong team cohesion and employees are often granted opportunities and encouraged to delve into areas beyond their job description.
Contribution to EXA2GREEN
CSCS will investigate the energy efficiency of two different aerosol chemistry packages, then proceed with optimising these, first for commodity CPUs, then for one or several commodity multi-core processors. The resulting contribution will be at least one energy-efficient aerosol chemistry prototype returned to the community. Additionally, CSCS's contribution includes a recommendation for an energy-efficient dedicated hardware platform to perform aerosol chemistry, and involvement in cross-cutting efforts, such as energy-aware libraries for the solution of ordinary differential equations.

Exa2Green Activities / Role in the project:
ETH main technical contact; technical coordinator of WP5, „Showcase for energy-optimized aerosol chemistry packages”.

 

Background and research/work focus:
I have worked for the last 20 years in the field of parallel computing and computational mathematics with a central focus on algorithms for the solution of atmospheric dynamics problems.

 

Among my previous projects were (1) the distributed memory parallelization of the Lin-Rood dynamical core within the Community Atmosphere Model, (2) participation in the design and implementation of the Earth System Modeling Framework (ESMF), and (3) the port of the ICON non-hydrostatic dynamical core to GPUs within the PRACE 2IP work package 8.

 

Parallel numerical linear algebra is one of my hobbies. I am the author of the PLUMP and PILGRIM libraries for parallel grid manipulations, and in my spare time I am working on the port of the preconditioners for Krylov linear solvers to GPUs.

Joseph Charles
Exa2Green Activities / Role in the project:
  • Reduction of energy-to-solution for the COSMO-ART-M7 on existing CPUs
  • Extension of COSMO-ART-M7 for multi-core architectures
  • Investigations of COSMO-ART-M7 for future energy-efficient architectures
  • Depending on the possibilities available and the maturity of these experimental platforms, the prototype may be extended to allow the use of new architectures.

 

Background and research/work focus:
My previous research activities were performed in collaboration with Dimitri Komatitsch from CNRS (France) and Daniel PETER and Prof. Jeroen TROMP from the Theoretical & Computational Seismology research group in Princeton University (USA), focusing on imaging Earth's interior. My work focused on the development of two highly optimized spectral finite-element open source software, both running on CPU or GPU clusters, for the numerical study of seismic waves propagation in geological and oceanic structures (SPECFEM3D Cartesian/SPECFEM3D GLOBE).
The objective was to enhance the numerical solver on parallel computers and increase its computational speed, by developing a multi-GPU acceleration on a CUDA-MPI hybrid model.
