<div>Hi Mahzad,<br>
<br>
Everything you are doing looks fine to me. It's possible that we have a bug that is being triggered in darshan-convert (this is a command line utility called within darshan-summary-per-file.sh to help split up the data). <br>
<br>
Are you able to run darshan-job-summary.pl and/or darshan-parser on the log file?<br>
<br>
Can you share your log file for us to have a look at it and see if we can reproduce?<br>
<br>
thanks!<br>
-Phil<br>
