<div dir="ltr">Hi Lisa,<br>As far as I get the main idea of your blueprint it's something that we've planned to do in the "future". So, yes this idea is something that Blazar should do. But the problem is that we have some real-time problems.<br>I mean we are in rename process (yeah, it takes real long time for us) and our devstack job is broken (I tried to fix it, but have some problems with time). If you want to discuss how we, I mean Blazar core-team, and you,<br>team from <span style="color:rgb(51,51,51);font-family:sans-serif;font-size:12px;line-height:18px">the Italian National Institute for Nuclear Physics, can collaborate we can discuss it in irc on blazar-channel, I think. We just need to appoint a time slot for that. May be week after summit? If I understand you'll be there this week.<br></span></div><div class="gmail_extra"><br clear="all"><div><div class="gmail_signature"><div dir="ltr"><font color="#888888"><div dir="ltr"><div style="color:rgb(34,34,34);font-size:13px;font-family:arial,sans-serif"><p style="font-size:small;margin:0px;font-family:Helvetica">

              <div>Hi Sylvain,<br>
                <br>
                thanks for your answer.<br>
                Actually we haven't yet developed that because we'd like
                to be sure that our proposal is fine with BLAZAR.<br>
                We already implemented a pluggable advanced scheduler
                for Nova which addresses the issues we are experiencing
                with OpenStack in the Italian National Institute for
                Nuclear Physics. This scheduler named FairShareScheduler
                is able to make OpenStack more efficient and flexible in
                terms of resource usage. Of course we wish to integrate
                our work in OpenStack and so we tried several times to
                start a discussion and a possible interaction with the
                OpenStack developers, but it seems to be so difficult to
                do it.<br>
                The GANTT people suggested us to refer to BLAZAR because
                it may have more affinity with our scope. Is it so?
                Therefore, I would appreciate to know if you may be
                interested in our proposal.<br>
                <br>
                Thanks for your attention.<br>
                Cheers,<br>
                Lisa<br>

                  Such component's name is FairShareScheduler and <br>

                    Hi Lisa,<br>
                    <br>
                    At the moment, I'm quite occupied on Nova to split
                    out the scheduler, so I can't hardly dedicate time
                    for Blazar. That said, I would appreciate if you
                    could propose some draft implementation attached to
                    the blueprint, so I could glance at it and see what
                    you aim to deliver.<br>

                            <br>
                            my name is Lisa Zangrando and I work at the
                            Italian National Institute for Nuclear
                            Physics (INFN). In particular I am leading a
                            team which is addressing the issue
                            concerning the efficiency in the resource
                            usage in OpenStack. <br>
                            Currently OpenStack allows just a static
                            partitioning model where the resource
                            allocation to the user teams (i.e. the
                            projects) can be done only by considering
                            fixed quotas which cannot be exceeded even
                            if there are unused resources (but) assigned
                            to different projects. <br>
                            We studied the available BLAZAR's
                            documentation and, in agreement with Tim
                            Bell (who is responsible the OpenStack cloud
                            project at CERN), we think this issue could
                            be addressed within your framework. <br>
                            Please find attached a document that
                            describes our use cases (actually we think
                            that many other environments have to deal
                            with the same problems) and how they could
                            be managed in BLAZAR, by defining a new
                            lease type (i.e. fairShare lease) to be
                            considered as extension of the list of the
                            already supported lease types. <br>
                            I would then be happy to discuss these ideas
                            with you. <br>
                            <br>

                          Hi Lisa,<br>
                          <br>
                          Glad to see you're interested in Blazar.<br>
                          <br>
                          I tried to go thru your proposal, but could
                          you please post the main concepts of what you
                          plan to add into an etherpad and create a
                          blueprint [1] mapped to it so we could discuss
                          on the implementation ?<br>
                          Of course, don't hesitate to ping me or the
                          blazar community in #openstack-blazar if you
                          need help with the process or the current
                          Blazar design.<br>
