In addition, the libgslcbls and FORTRAN- interface FGSL (1.2.0) are provided. Both, the shared and the static version are available.

Modules and usage of GSL at HLRN
The library is included in several software packages. A module file gives access to a few binaries, gsl-config, gsl-histogram, gsl-randist.
module load gsl/version
sets environmental variables:
- LD_RUN_PATH
- PATH
- MANPATH
- INFOPATH
- PKG_CONFIG_PATH
module help gsl/version
delivers the path to the libraries. Sophisticated tools and programmers use gsl-config of pkg-config.
Installation at HLRN
GSL is build from source. The current version is build with several compilers. High end optimisation is used.All libraries passed through the basic checks. With high end optimoisation with intel compilers the linear algebra solvers do not converge. fp-model strict is used. read more
