<p class="MsoNormal">I downloaded recently Darshan version
2.3.0. As part of a team within Intel Corporation, I am
conducting a broad survey of high performance tools. I have
reviewed the documentation posted on the Darshan website, the
source code, and the mail list archives, but I have a few
remaining inquiries on which I hope you can assist me. All of
the following questions are from the perspective of my team
bringing up Darshan on our newest and forthcoming high end
server class machines and possibly becoming contributors to
the source base:<o:p></o:p></p>

Hi Reshawn,<br>
<br>
Thank you for your interest, and let us know what we can do to
help! I'll try to answer your specific questions inline below:<br>

1. In version 2.3.0, what is the most recent Intel architecture
supported?<o:p></o:p><br>

<br>
Any Intel compiler should work fine, but we do not often test with
the Intel MPI libraries. As of 2012 there was a problem
intercepting I/O calls from Fortran program using the Intel MPI
library (see <a class="moz-txt-link-freetext" href="https://software.intel.com/en-us/forums/topic/279445">https://software.intel.com/en-us/forums/topic/279445</a>).
I don't know if this problem still persists or not, though.<br>
<br>
Someone else on the mailing list might have experience with Darshan
and Intel MPI 5.x?<br>

<div class="WordSection1">2. If my team would like to add support
for new and upcoming platforms, what are your policies for
submitting patches and updates?<o:p></o:p><br>

<br>
Things are pretty simple: we are happy to accept patches under
Darshan's current license, and there is no contributor agreement.
I'm not a lawyer though, so if you have more specific follow-up
questions it might be best for me to look into it more formally
off-list.<br>
<br>
I should also note that we have a development branch to modularize
Darshan further (this will one day be a 3.x release). That branch
isn't anywhere near mature yet, but it might be of interest for
development at some point in the future.<br>

centralized or distributed?<o:p></o:p><br>

<br>
ANL and NERSC are the primary organizations involved in the project,
but the day-to-day software development is mostly centralized at
ANL.<br>

<br>
Yes. It has some configure-time checks to adjust the wrapper
prototypes depending on which API version is present.<br>
