<p>Comment (by Roland Haas):</p>
<p>This turned out to be mostly an issue with how the <code>-c</code> option was used. <code>-c</code> is the number of logical cores per MPI rank and was set as <code>@PPN@ / @NODE_PROCS@</code>. Howerver PPN in simfactory’s mdb files is (incorrectly if one believes the documentation string, but correctly when one checks how it is used) set to the number of physical cores per node. Somewhat sanely (in case one was to use hyperthreading) requesting 6 logical cores uses 3 physical cores along with their 3 hyperthreading partners.</p>
<p>Corrected in git hash <a data-is-external-link="true" href="https://bitbucket.org/simfactory/simfactory2/commits/8278a78695cd42fcf55f9ec23ffe095204e596e9" rel="nofollow">8278a78</a> "cori: allocate thread to logical cores rather than cores used" of <a data-is-external-link="true" href="https://bitbucket.org/simfactory/simfactory2" rel="nofollow">simfactory2</a> along with binding OMP threads to physical cores.</p>
