Organization: SAIC Date: Wed, 03 Sep 1997 12:33:19 -0700 Mime-Version: 1.0 Content-Type: text/plain; charset=us-ascii Content-Transfer-Encoding: 7bit Message-ID: <340DBB7F.3EE7047A@iris023.saic.com> Hello, I'm deviding my data structure in unequal blocks because I don't want to be restricted to even numbers of points or processors. For example if my array when I use only one processor is a(81,51) then when I use four processors the local arrays are PE 0 alocal(81,13) PE 1 alocal(81,13) PE 2 alocal(81,13) PE 3 alocal(81,12) The problem is when I have to write everything in a file. I cannot use MPI_gather to put the alocal arrays back into a(81,51) because I'm using unequal blocks. Is there an elegant way of this? Thanks! If you answer by email my correct address is shown below. Regards, Roberto -- Roberto Lionello ****I don't speak for SAIC**** SAIC, 10260 Campus Point Drive MS-C2, San Diego, CA 92121-1578, USA.
