Software platform for geophysical data processing: 
- Hundreds of small calculation codes (C, Fortran9x, C++, perl, bash, scilab, maxima, sage)
 - A few major codes corresponding to the kernel of GIM-labs know-how (C, Fortran9x, C++)
 
HPC: 
Our softwares are parallelized using both shared (OpenMP) and distributed (MPI) parallelism and can be run on HPC clusters of thousands of machines. 
Software Engineering: 
We use a linux platform for software engineering (IDE, compiler, profiler, debuger, valgrind, SVN, mercurial). 
Hardware: 
- File and calculation servers
 - Small linux PC cluster for testing
