Iceberg was decommissioned on 30th November 2020. Users of Iceberg need to switch to using ShARC and/or Bessemer instead.

GNU Scientific Libary (GSL)

The GNU Scientific Library (GSL) is a numerical library for C and C++ programmers. It is free software under the GNU General Public License.

The library provides a wide range of mathematical routines such as random number generators, special functions and least-squares fitting. There are over 1000 functions in total with an extensive test suite.


You can make the GSL available by running:

$ module load libs/gcc/4.9.2/gsl/2.3

This makes the GSL’s library files, header files, utility programs and documentation all accessible.

YOu can check that you are running the requested version:

$ gsl-config --version

When building software that uses the GSL you will need to link to it. From the GSL documentation:

To link against the library you need to specify both the main library and a supporting CBLAS library, which provides standard basic linear algebra subroutines. A suitable CBLAS implementation is provided in the library libgslcblas.a if your system does not provide one. The following example shows how to link an application with the library:

$ $CC example.o -lgsl -lgslcblas -lm

Another CBLAS implementation that you may want to use with the GSL is the Intel Math Kernel Library (MKL).


For documentation either run:

$ module load libs/gcc/4.9.2/gsl/2.3
$ info gsl

or visit the project website.

Installation notes

This section is primarily for administrators of the system.

The GSL was installed as a user wanted to build EIGENSOFT.

Version 2.3

This was compiled using GCC on an Intel x5650 node.

  1. cd to a scratch directory.

  2. Run this install script (

  3. Install this module file as /usr/local/modulefiles/libs/gcc/4.9.2/gsl/2.3
