GSL

Module

GNU Scientific Library (GSL) is now available in the 2022r2 software stack:

module load 2022r2
module load gsl

Compile your own GNU Scientific Library

GNU Scientific Library (GSL) is now available in the 2022r2 software stack.

It is quite easy to compile it yourself. On DelftBlue, you will need to do the following:

1. Load necessary modules:

   module load 2022r1
   module load compute
   module load gcc/11.2.0-midhpa4
   module load openmpi/4.1.1-urzuzcv
   

2. Get the GSL and create an install folder:

   wget https://mirror.ibcp.fr/pub/gnu/gsl/gsl-latest.tar.gz
   tar -zxvf gsl-latest.tar.gz
   cd gsl-2.7.1
   mkdir install
   

3. Configure, compile and install GSL:

   ./configure --prefix=${HOME}/tools/gsl-2.7.1/install
   make
   make check
   make install 
   

4. Check to see if GSL works as intended: First, create the following program and name it example.c:

   #include <stdio.h>
   #include <gsl/gsl_sf_bessel.h>
   
   int
   main (void)
   {
       double x = 15.0;
       double y = gsl_sf_bessel_J0 (x);
       printf ("J0(%g) = %.18e/n", x, y);
       return 0;
   }
   

   Second, compile and link the program with the following commands:

   export LD_LIBRARY_PATH=${LD_LIBRARY_PATH}:${HOME}/tools/gsl-2.7.1/install/lib
   gcc -Wall -I${HOME}/tools/gsl-2.7.1/install/include -c example.c
   gcc -L${HOME}/tools/gsl-2.7.1/install/lib example.o -lgsl -lgslcblas -lm
   

   Finally, run your program!

   ./a.out
