</div>NEVER truncate an error message. (We have to remind people of this<br>
every day. Always send the whole thing.)<br>

MPI-IO works for me and in our tests, so we should figure out what<br>

</div>Time it so we can compare output performance using the different methods. </blockquote></div><br></div></div>
