Rational thingy:
Rationale. Potatoes. :-)
MPI_Count is used to communicate both the number of elements in a datatype and the bounds of a datatype. The number of elements in a datatype is specified at creation time using a C int or Fortran INTEGER. The bounds may be specified using an MPI_Aint.
This is good. I would change the wording slightly -- let's not use the verb "communicate" here: "MPI_Count explicitly specifies the number of elements in a datatype, and therefore implicitly specifies the bounds of that datatype. The number of elements in a datatype is specified at creation time using a C int or Fortran INTEGER. The extent of a datatype is expressed using an MPI_Aint. How's that? -- Jeff Squyres jsquyres_at_[hidden] For corporate legal information go to: http://www.cisco.com/web/about/doing_business/legal/cri/
