I suspect, from glancing at the first example at http://www.gnu.org/software/gsl/manual/html_node/ODE-Example-programs.html, you could achieve parallelization atop stock GSL builds with fewer than 6 pragmas. I also suspect that by using OpenMP tasks over the coarser granularity concept (1 ODE) instead of the parallel-fors over the finer granularity method (1 step) you may see better overall performance. - Rhys
