Keywords : scientific computing, numerical computing, highperformance computing, parallel computing, grid computing, accuracy, linear algebra, linear systems, leastsquares problems, eigenproblems, sparse matrices, environment, geosciences.
Main research areas
The team SAGE undertakes research on highperformance computing and deals with three subjects :

numerical algorithms, mostly large sparse linear algebra,

large scale high performance computing, involving parallel and grid computing,

environmental and geophysical applications, mostly in hydrogeology.
These three subjects are highly interconnected: the first topic aims at designing numerical algorithms, which will lead to high performances on parallel and grid architectures and which will be applied in geophysical models.
