Hello all, <br><br>I am reading pgm images with MPI_file_read.<br><br>Until now I read a file only as shown below: <br><br>
------------------------------------------------------------------<br>
-                                                                -<br>
-            Pr 0                                              - <br>
------------------------------------------------------------------<br>


-                                                                -<br>

-            Pr 1                                              - <br>------------------------------------------------------------------<br>
