<div class="moz-cite-prefix">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>
Thanks,<br>

as you suggested me few weeks ago, I created the blueprint (<a

I will be in Paris the next week at the OpenStack Summit, so
it would be nice to talk with you and the BLAZAR team about
my proposal in person.<br>
What do you think?<br>
<br>
thanks in advance,<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>
Thanks in advance, <br>
Lisa <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>
<br>
Thanks,<br>
-Sylvain<br>
