[mpich-discuss] View of processors

Hello all,

I am reading pgm images with MPI_file_read.

Until now I read a file only as shown below:

------------------------------------------------------------------
-                                                                -
-            Pr 0                                              -
------------------------------------------------------------------
-                                                                -
-            Pr 1                                              -
------------------------------------------------------------------
-                                                                -
-            Pr 2                                              -
------------------------------------------------------------------
-                                                                -
-            Pr 3                                              -
------------------------------------------------------------------

This time I have to read it as shown below. Is it possible to say the
processes to read the file like this:

------------------------------------------------------------------
-                             -                                  -
-                             -                                  -
-            Pr 0           -            Pr 1                -
-                             -                                  -
------------------------------------------------------------------
-                             -                                  -
-            Pr 2           -            Pr 3                -
-                             -                                  -
-                             -                                  -
------------------------------------------------------------------

Can we give this structure with *MPI_Set_view or something else?

*Best Regards,
