This is more of a general numerical ODE or Sundials usage question rather than a cygwin specific one, but I would try openmp or mpi on your function evaluations first, if that's taking most of the time. Do you know whether sundials is thread-safe? -Tony -- Problem reports: http://cygwin.com/problems.html FAQ: http://cygwin.com/faq/ Documentation: http://cygwin.com/docs.html Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple
