<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1F497D">Thanks for getting back to me! Here at TACC, we are trying to do some Gromacs benchmarking on Stampede and the Stampede 1.5 (our latest KNL machine) and try to
publish the results on conferences/ tutorials. We could easily make some systems for that purpose. However, we feel it’s always better to get the “official” ones from the developer. As such, it will be great if you could share those files with us.<o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1F497D">Speaking of KNL, at TACC we have received first 500 nodes from intel a couple month ago. Those nodes will eventually become the Stampede 1.5 and hopefully be
in production later this year. So I was wondering, if you guys have any plan on testing/optimizing Gromacs code no KNLs in the near future? <o:p></o:p></span></p>

<p class="MsoNormal">Yes we've had a few requests for these. I can share e.g. the .tpr files easily enough but attempting to reproduce them requires driver scripts to scan parameters, etc. and I don't have time right now to make those usable in the hands of
others on arbitrary HPC platforms and job schedulers. What's the purpose of the benchmarking? Are you better served by getting examples of actual .tpr files used by your users, and using those?<o:p></o:p></p>
