Ok, I need a little Fortran help. :)

Don't we all? :-)

Example 4.1.14, page 112, the calls to MPI_Type_vector passes a blocklength of 1. How do I change the example to specify that the '1' is of type MPI_COUNT_KIND?

Do you mean example 4.1.13? I don't see the use of MPI_Type_vector in 4.1.14... The easiest way to pass a "1" of MPI_COUNT_KIND through as a parameter is to declare a new variable of that type and then pass that. I know there's a way to cast an integer to that type in the call to MPI_TYPE_VECTOR itself (i.e., without making a new variable), but I don't remember the exact syntax. INTEGER (kind = MPI_COUNT_KIND) :: count count = 1 ... call MPI_TYPE_VECTOR(9, count, 2, MPI_REAL, oneslice, ierr) Make sense? -- Jeff Squyres jsquyres_at_[hidden] For corporate legal information go to: http://www.cisco.com/web/about/doing_business/legal/cri/
