Attention

Following the recent operating system upgrade, software listings and module load commands now reflect the upgraded system. Some examples and notices are still being updated and may contain outdated guidance.

GSL

Guidance last updated: 16 October 2026

The GNU Scientific Library (GSL) is a collection of routines for numerical computing. The routines have been written from scratch in C. See here for the types of routines that the GSL provides.

Documentation: https://www.gnu.org/software/gsl/doc/html/index.html

Usage

After connecting to Stanage (see Establishing a SSH connection), start an interactive session with the following command:

srun --pty bash -i

The GSL library can be loaded by running one of:

module load GSL/2.8-GCC-14.3.0
module load GSL/2.8-GCC-13.3.0

module load GSL/2.8-GCC-14.3.0

which also loads the matching GCC compiler.

Example

Save this example program as test.c (taken from the GSL documentation):

#include <stdio.h>
#include <stdlib.h>
#include <gsl/gsl_sf_bessel.h>

int main (void) {
  double x = 5.0;
  double y = gsl_sf_bessel_J0(x);

  printf("J0(%g) = %.18e\n", x, y);

  return EXIT_SUCCESS;
}

Build this using:

gcc -Wall -o test test.c $(gsl-config --cflags --libs)

Then run using:

./test

which should print the following (correct to double-precision accuracy):

J0(5) = -1.775967713143383198e-01

The gsl-config command supplies the include paths and libraries for the loaded GSL module.

Installation notes

GSL was installed using Easybuild, build details can be found in $EBROOTGSL/easybuild with a given module loaded.
