Funky. I'm not a fortran expert, but I didn't know what you couldn't put a parameter in a common block. I guess that's a difference between OMPI and MPICH -- sorry! > If I try to pass MPI_WORLD_COMM to a subrotine as one of the subroutine > argument, it aborts at run time whe it comes to using it in an MPI_Bcast call > > *** An error occurred in MPI_Bcast > *** on communicator MPI_COMM_WORLD > *** MPI_ERR_TYPE: invalid datatype That shouldn't be. But it does seem to imply that your passing a bad datatype, not a bad communicator. Can you send a small code example that shows the problem? -- Jeff Squyres jsquy...@cisco.com For corporate legal information go to: http://www.cisco.com/web/about/doing_business/legal/cri/
