Recruitment of a HPC engineer to improve AMR in ParFlow

Jose Fonseca has joined Masion de la Simulation in May 2019 as a HPC engineer. In the framework of the project EoCoE-II, he will work on the development of an AMR (Adaptive Mesh Refinment) version of the scientific code ParFlow dedicated to the hydrological simulation of surface, sub-surface and ground water flow. ParFlow is used in research fields related to water cycle. He can couple to meteorological and climatic simulation codes. To improve Parflow, Jose Fonseca will use the AMR library P4est. For this aim, Maison de la Simulation is strongly collaborating with the Jülich research center. In parallel, the code is being optimized for GPU. His contract at Maison de la Simulation is funded during 2 years with EoCoE-II.

Project description

The European project EoCoE-II is the second version for 3 years of the first project EoCoE (Energy oriented Centre of Excellence in computing applications). It aims at using the increasing computing power of super-computers to accelerate the European transition to energy source with low-carbon emission. It is one of the 8 centers of excellence in the simulation domain in the framework of the European program Horizon 2020. The project is built around 18 partners from 7 different countries forming a network of scientists and experts in numerical simulation and HPC including 3 computing centers. The project focuses on 5 application domains : wind, materials, meteorology, hydrology, fusion. Transversely, the project is structured around 5 technical pillars : numerical applications, programming models, linear algebra, input-output and ensemble simulations.

18 partners coming from 7 European countries

Each application domain will focus on few flagship codes to reach ambitious scientific objectives on future exascale super-computers. The total project budget is of the order of 8 millions euros shared between all partners depending on the allocated tasks.

Maison de la Simulation within EoCoE-II

Maison de la Simulation via CEA is an important partner of this project. It is a member of the board in partnership with the research center of Jülich and ENEA (Italian National Agency for New Technologies, Energy and Sustainable Economic Development). Maison de la Simulation is also involved in scientific and technical aspects of the project.

Maison de la Simulation supervises the project as a board member.

It is responsible for the technical pillar on programming models (Work Package 2) and is involved in the optimization of the hydrology code ParFlow for sub-surface water flow simulation. It is as well involved in the technical pillar on input-output (Work Package 4) to integrate the PDI library in many applications.
