Software

The typcial installation of a intel-server has the INTEL Compiler suite (intel-parallel-studio, intel-oneapi) 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
  • 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.

Currently installed modules
