<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>
Thanks,<br>

as you suggested me few weeks ago, I created

target="_blank">https://blueprints.launchpad.net/blazar/+spec/fair-share-lease</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>

<blockquote type="cite">Hi all, <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>
