Hi all,<br><br>    I need to read a file, using MPI_set_view. The problem occurs when the file is so large that the offset that I need to provide to the MPI_set_view is larger than the maximum value for an integer.  For example I need to set the offset to 3826145886. In some documentation I&#39;ve read the offset is a long, but in other it indicates its an integer.<br>

<br> Is there any possible work around this? Could the offset be set to negative, and if so, will it start at the end of the file? <br><br> I have installed  mpich2-1.3.1.<br><br>Thank you,<br><br>            <br>
