Software and environment modules
The webpage Software gives you information about available software on the NHR systems.
NHR provides a number of compilers and software packages for parallel computing and (serial) pre- and postprocessing:
- Compilers: Intel, GNU
- Libraries: NetCDF, LAPACK, ScaLAPACK, BLAS, FFTW, ...
- Debuggers: Allinea DDT, Roguewave TotalView...
- Tools: octave, python, R ...
- Visualisation: mostly tools to investigate gridded data sets from earth-system modelling
- Application software: mostly for engineering and chemistry (molecular dynamics)
Environment Modules are used to manage the access to software/libraries. The module
command offers the following functionality.
- Show lists of available software
- Enables access to software in different versions
blogin1:~ $ module avail ... blogin1:~ $ module load intel Module for Intel Parallel Studio XE Composer Edition (version 2019 Update 5) loaded. blogin1:~ $ module list Currently Loaded Modulefiles: 1) sw.skl 2) slurm 3) HLRNenv 4) intel/19.0.5(default)
To avoid conflicts between different compilers and compiler versions, builds of most important libraries are provided for all compilers and major release numbers.
