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 2.3
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.aif 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.
This section is primarily for administrators of the system.
The GSL was installed as a user wanted to build EIGENSOFT.
