Scientific calculation - data mining

The IT dedicated to the intensive exploitation of large volumes of data is mainly related to the research activities of the Ondes team, activities related to methods based on ambient noise. This expertise is at the interface between geophysicists, HPC specialists and databases in the context of national and European projects.

The codes and associated documentation developed as part of the activity "Data Mining" are accessible in the OSUG Forge (restricted access).

– Beamforming tools :documentation and code
– Conversion / preprocessing / correlation tools : documentation and code

The business expertise of the technical staff involved are :

– Optimization of sequential codes (numerical methods, choice of languages,...)
– Parallelization of applications (MPI, OpenMP, make)
– Application deployment
– Calculation on grid (CiGri v3)
– iRODS : transfer techniques, metadata management,...
– IO parallel
– Signal processing : hole management, data decimation,...
