Attention
WARNING: From 9am on 19th August until 5pm on 2nd September there will be no access to the Stanage HPC cluster.
We will send an email to notify you when Stanage is back online and available for job submission.
Attention
The ShARC HPC cluster was decommissioned on the 30th of November 2023 at 17:00. It is no longer possible for users to access that cluster.
GSL
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.
Usage
The GSL library can be loaded using either:
module load libs/gsl/2.4/gcc-6.2
module load libs/gsl/2.4/gcc-8.2
Example
A example program that uses the GSL (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 -lgsl -lgslcblas -o test test.c
Then run using:
./test
which should print the following (correct to double-precision accuracy):
J0(5) = -1.775967713143382642e-01
NB generally, you may not need to compile using -lgslcblas
depending on which GSL routines you are using.
Installation notes
2.4 built with GCC 8.2/6.2 (same install script):
install script
;install log
;modulefile
. The installation was tested during the build process usingmake check
.
