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 The GNU Scientific Library (GSL)- a numerical library for C and C++ programmers
