<div dir="ltr"><div><div>CPU frequency is an import performance parameter, currently nova drivers just report cpu_info without frequency. we stored the compute node cpu_info in database with colum compute_nodes.cpu_info, we can add the frequency easily.<br><br></div>The usage of cpu frequency I can think is used to schedule to meet applications which need high frequency. add a frequency based filter ?<br>if we need this , I would like to propose a spec for this .<br><br><br></div><div>There are two steps to leverage cpu frequency:<br>1. report cpu frequency and record the value, nova hypervisor-show will include the value .<br><br>2. filter compute nodes based cpu frequency.<br> add a new scheduler filter to do that<br><br>before I start to do these stuff. I would like to your input .<br><br></div><div>Do we need leverage CPU frequency in Nova ? <br>if yes, do we need a new filter or leverage existing filter to use frequency ?<br></div><div><div><div><br>-- <br><div class="gmail_signature"><div dir="ltr"><div>ChangBo Guo(gcb)</div></div></div>
