<p class="MsoNormal">It’s not clear to me how to interpret darshan_analyzer’s use of the rank field.<o:p></o:p></p>
<p class="MsoNormal">Intuitively I’m thinking it would be the opposite (-1 == shared == multi), so I think<o:p></o:p></p>
<p class="MsoNormal">I’m missing something fundamental here, and I hope someone can clarify for me.<o:p></o:p></p>
