Newsgroups: comp.parallel.mpi From: Yon Han CHONG Subject: MPI-2: MPI_TYPE_CREATE_SUBARRAY (Fortran binding issue) Organization: Cranfield University Date: Tue, 10 Mar 1998 15:47:15 +0000 Mime-Version: 1.0 Content-Type: text/plain; charset=EUC-KR Content-Transfer-Encoding: 7bit Message-ID: <35056083.B5F717B2@cranfield.ac.uk> In MPI-2 it is defined that the begining of subarrary index should be a positive numbers. In C, this does make sense. You do not want to go over the boundary. In Fortran, this is restrictive because sometimes it is more convient to define an array as following: integer, parameter :: N=5 real, dimension(-1:N+2) :: a_local "a_local" cannot be a subarray since the index start from a negative number. -- ---------------------------------------------------------------------- Yon Han Chong | Flow Control and Prediction Group | Tel: + 44 1234 750 111 ext. 5420 Cranfield College of Aeronautics | E-mail: Y.H.Chong@cranfield.ac.uk Cranfield University | Fax: + 44 1234 752 149 United Kingdom | Mobile: + 44 958 381 395 ----------------------------------------------------------------------
