[Help-gsl] What to do with my modifications to some GSL functions

[Maxime Boissonneault]

Hi,
I have written a high-performance computing code to compute the 
evolution of a system using differential equation solving. I'm running 
it on a multi-core architecture, so that in my code, I can make use of 
parallel programming techniques such as OpenMP.

In order to get even better performances, I made some modifications to 
rkf45.c (I use Runge-Kutta-Fehlberg algorithms for integration of ODEs). 
The modifications are simply to add calls to OpenMP before for loops 
(#pragma omp for shared(...) private(...) ).

I was wondering what to do with these modifications ? Is there a way to 
submit them for approval to GSL so that they are integrated to the 
library ? Should I simply copy the required files from GSL source code, 
modify them and link them instead of the library when compiling my code ?

The latter (copying the files and modify them) is what I did up to now. 
However, I plan to publish this code under GPL license, and I'm then 
wondering what I should do with the copyrights for these modifications.

Thank you,
