Or they don't have explicit interfaces for all MPI functions. If they don't have an explicit interface for MPI_ABORT, then it follows the same implicit rules that otherwise apply in Fortran (e.g., what all mpif.h interfaces I know do). Indeed, OMPI defaults to only having explicit interfaces for MPI functions that do not take "choice" buffers (e.g., MPI_INIT, but not MPI_SEND) because of various complicates due to that (that will be changing sometime in the not-distant future, though -- stay tuned!). -- Jeff Squyres jsquy...@cisco.com For corporate legal information go to: http://www.cisco.com/web/about/doing_business/legal/cri/
