So, you are using an interim master build, and you want to use it with RHEL 7.3 but there is something necessary for KNL that is missing from the default RH-supplied kernel? Could you please elaborate as to what that is?</p> <p>Thanks</p> <p>Peter</p> <p>The Lustre client I compiled from the interim master build contains an error exposed only on KNL. You already have that error (and the fix) in <a href="https://jira.whamcloud.com/browse/LU-8703" title="rework CPU partition code" class="issue-link" data-issue-key="LU-8703"><del>LU-8703</del></a>. I need an interim master build WITH the fix included</p> <p> </p> <p>Michael</p> <p>So by "that error" you mean the unnecessary error messages that are generated? Having discussed with engineering, there is no functional change for this patch. And do you specifically want just that change on that specific commit or would landing the fix to the current tip of master (or based on the 2.9 release) meet your needs?</p> <p>Peter</p> <p>Michael, there is a new build underway with all of the <a href="https://jira.whamcloud.com/browse/LU-8703" title="rework CPU partition code" class="issue-link" data-issue-key="LU-8703"><del>LU-8703</del></a> patches against master (essentially 2.9.0) that will be available at:</p> <p> <a href="https://build.hpdd.intel.com/job/lustre-reviews/43020/" class="external-link" target="_blank" rel="nofollow noopener">https://build.hpdd.intel.com/job/lustre-reviews/43020/</a></p> <p>in a couple of hours, as our build system is currently backlogged.</p> <p>could you please point me to the GIT entry?</p> <p>The last patch in the series is <a href="https://review.whamcloud.com/24304" class="external-link" target="_blank" rel="nofollow noopener">https://review.whamcloud.com/24304</a> or <a href="https://git.hpdd.intel.com/?p=fs%2Flustre-release.git;a=commit;h=5a928f213bfb24a6c7e5ae353bc7872528e32a1d" class="external-link" target="_blank" rel="nofollow noopener">https://git.hpdd.intel.com/?p=fs%2Flustre-release.git;a=commit;h=5a928f213bfb24a6c7e5ae353bc7872528e32a1d</a> though it should be noted that last patch in the series has not yet been reviewed.</p> <p>The issue is resolved by specific configuration in lustre.conf</p> <p>Dmitry, is Michael aware of the specific lustre.conf configuration?  Otherwise, please pass that information on in this ticket.</p> <p><b>From:</b> Hebenstreit, Michael <br/> <b>Sent:</b> Tuesday, December 13, 2016 1:52 AM<br/> <b>To:</b> Eremin, Dmitry &lt;dmitry.eremin@intel.com&gt;<br/> <b>Subject:</b> RE: problems with KNL and Lustre</p> <p>Thanks, that seems to solve my problem for now</p> <p>You can close 8909</p> <p><b>From:</b> Eremin, Dmitry <br/> <b>Sent:</b> Friday, December 9, 2016 1:52 AM<br/> <b>To:</b> Hebenstreit, Michael &lt;<span class="nobr"><a href="mailto:michael.hebenstreit@intel.com" class="external-link" target="_blank" rel="nofollow noopener">michael.hebenstreit@intel.com^{<img class="rendericon" src="https://jira.whamcloud.com/images/icons/mail_small.gif" height="12" width="13" align="absmiddle" alt="" border="0"/>}</a></span>&gt;<br/> <b>Subject:</b> RE: problems with KNL and Lustre</p> <p>Hi Michael,</p> <p>I’m reworking CPU partition code now. This work is not complete yet. It’s not implemented in optimal way for KNL so far. Therefore I would recommend you to use the following settings in lustre.conf for KNL.</p> <p><b>options libcfs cpu_pattern="" cpu_npartitions=34</b></p> <p><b>options ptlrpc ptlrpcd_partner_group_size=4</b></p> <p>Dmitry.</p> <p>yes, that works</p> <p>thanks for help</p> Development Rank 1|hzyxiv: Rank (Obsolete) 9223372036854775807
