 ## Software
 
+The typcial installation of a intel-server has the INTEL Compiler suite (`intel-parallel-studio`) and the open source GNU Compilers installed. Based on these two different compilers (`intel`, `gnu`), there are usually two version of each scientific software.
+Major Libraries:
+ - OpenMPI (3.1.6, 4.0.5)
+ - HDF5 
+ - NetCDF (C, Fortran)
+ - ECCODES from [ECMWF](https://confluence.ecmwf.int/display/ECC)
+ - Math libraries e.g. intel-mkl, lapack,scalapack
+ - Interpreters: Python, Julia
+ - Tools: cdo, ncl, nco, ncview
+
+These software libraries are usually handled by environment modules.

+Using [environment modules](https://modules.readthedocs.io/en/latest/) it is possible to have different software libraries (versions, compilers) side-by-side and ready to be loaded. Be aware that some libraries are dependent on others. It is recommended to load the highest rank library first to check what dependencies are loaded as well. e.g.:
+```
+$ module load eccodes/2.18.0-gcc-5.3.0 
+Loading eccodes/2.18.0-gcc-5.3.0
+  Loading requirement: zlib/1.2.11-gcc-5.3.0 openmpi/3.1.6-gcc-5.3.0 hdf5/1.10.7-gcc-5.3.0 netcdf-c/4.7.4-gcc-5.3.0

+loads the `ECCODES` library and all dependencies. e.g. intel or gnu compilers, as indicated by the naming.
+```
