Hi Jean,<br>
<br>
Are you actually performing any read or write operations to a file
in the application you are linking with Darshan? DXT only traces
reads and writes, so if you are just opening a file (for instance),
it shouldn't produce any DXT data. <br>
<br>
If your application is doing reads/writes, there should be DXT data
if you enabled it properly. Did you run 'export
DXT_ENABLE_IO_TRACE='? Note that you need to include the trailing
equal sign, even if you aren't setting a value for the amount of
memory to use. For example:<br>
<br>
'export DXT_ENABLE_IO_TRACE=' will give you the default 4MiB buffer
per process for tracing <br>
'export DXT_ENABLE_IO_TRACE=8' will instead allocate 8MiB buffers
per process<br>
<br>
Thanks,<br>
