[Help-gsl] Question about GSL performance under OpenMP

[Pedro Gardete]

Hi,

I need to go through many systems of equations, which I'm using
the gsl_multiroot_fsolver_hybrid method to solve for. The systems solve
fine, but when I put them inside an OpenMP loop (each thread solves one
system at a time and stores the result) the performance invariably comes
down for each thread as I add more. Should this be expected given that the
threads are independent (ie, don't wait for each other)?

Thanks,
Pedro
