<div dir="ltr"><div>About 2 months ago, I tried using Darshan to trace a TensorFlow2 DL training. I could not trace the input. What I _think_ happens is the TF2 uses mmap() for reading the input files and I don't think Darshan can capture that file IO. But I'm not a Darshan expert so perhaps someone has tried this before and can help</div><div><br></div><div>(BTW - it's possible to build TensorFlow so it doesn't use mmap() for reading files.)<br></div><div><br></div><div>Jeff</div><div><br></div><div><br></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Mon, Jul 6, 2020 at 1:08 PM Devarajan, Hariharan <<a href="mailto:hdevarajan@anl.gov">hdevarajan@anl.gov</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">
