The GNU Scientific Library (GSL) is a free numerical software package for C and C++ covering a range of subject areas including:

  • BLAS (level 1, 2, and 3) and linear algebra routines
  • Fast Fourier transform (FFT) functions
  • Numerical integration
  • Random number generation function

Usage on Vilje

Load one of the gsl and the corresponding intel compiler modules to use the GSL library on Vilje, e.g.:

$ module load intelcomp/13.0.1 gsl/1.16

The library header files are installed in a subdirectory gsl of the main installation directory that must prefix preprocessing include statements, see e.g. the example program blas_test.c below. The header files define functions to have extern "C" linkage when included in C++ programs allowing functions to be called directly from C++. The GSL library is available in both shared and static versions.

Example program

blas_test.c Expand source

Compile and link the program using the Intel compiler, adding:

$ icc blas_test.c -lgsl -lgslcblas
