Hi Colm,<br>
<br>
The '--file' flag gives some details on the accesses to files of
different types:<br>
<br>
* total => files of all types (i.e., all other types below
combined)<br>
* read_only => the file was only read<br>
* write_only => the file was only written<br>
* read_write => the file was both read and written<br>
* unique => the file was accessed by a single rank<br>
* shared => the file was accessed by every application rank<br>
<br>
For each file type, the first column is the count of files for that
type, the second column is number of bytes moved to/from the file
for that type, and the third column is the maximum file offset
accessed.<br>
<br>
I'm making a note to better document what kind of data each of the
parser flags outputs for our next release so hopefully its more
clear. In the meantime, you can see more detailed documentation on
various Darshan tools here:

<div dir="ltr">Hi,
<div><br>
</div>
<div>When using the "--file" flag for the darshan-parser tool, I
was a little unsure about what certain figures meant. Under
"files" in the POSIX/MPIIO sections, what do the three figures
following "total", "read_only", "write_only" (etc.) mean?</div>
<div><br>
</div>
<div>Example:</div>

</div>
<div>
<div># *******************************************************</div>
<div># POSIX module data</div>
<div># *******************************************************</div>
<div><br>
</div>
<div># files</div>
<div># -----</div>
<div># total: 15 404420357 201111068</div>
<div># read_only: 4 203309289 201111068</div>
<div># write_only: 1 201111068 201111068</div>
<div># read_write: 0 0 0</div>
<div># unique: 13 203309289 201111068</div>
<div># shared: 2 201111068 201111068</div>
</div>
<div><br>
</div>
<div>For "total", what do the "15 404420357 201111068" mean?</div>
<div><br>
</div>
<div>Thanks,</div>
<div>Colm</div>
