Newsgroups: comp.parallel.mpi From: Yon Han CHONG Subject: Constructing a datatype for 3D array Organization: Cranfield University Date: Thu, 05 Mar 1998 14:30:21 +0000 Mime-Version: 1.0 Content-Type: text/plain; charset=EUC-KR Content-Transfer-Encoding: 7bit Message-ID: <34FEB6FD.2A58C7A0@cranfield.ac.uk> I want to divide 3D array into 3 directions and their boundaries are exchanged in all 3 directions. I would rather construct a datatype to define the potion of array to be sent and received than to pack and unpack 3D array into 1D buffer for communication. Did anybody try this? -- ---------------------------------------------------------------------- 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 ----------------------------------------------------------------------
