Hi Nikolay,
yes I'm in Paris this week. That's good!! See you in irc the next week.
Thanks a lot.
Cheers,
Lisa

Oggetto: Re: [openstack-dev] [blazar]: proposal for a new lease type
Hi Lisa,
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.
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,
team from 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.

Hi Lisa, Sylvain,
I'll take a look at blueprint next week and will try to left some feedback
about it.
Stay tuned.

Hi Sylvain,
thanks for your answer.
Actually we haven't yet developed that because we'd like to be sure that our
proposal is fine with BLAZAR.
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.
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.
Thanks for your attention.
Cheers,
Lisa
Such component's name is FairShareScheduler and

Dear Sylvain and BLAZAR team,
I'd like to receive your feedback on our blueprint
(https://blueprints.launchpad.net/blazar/+spec/fair-share-lease) and start a
discussion in Paris the next week at the OpenStack Summit. Do you have a time
slot for a very short meeting on this?
Thanks in advance.
Cheers,
Lisa
Hi Lisa,
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.
Thanks,

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

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.
What do you think?
thanks in advance,
Cheers,
Lisa

Hi all,
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.
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.
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.
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.
I would then be happy to discuss these ideas with you.
Thanks in advance,
Lisa
Hi Lisa,
Glad to see you're interested in Blazar.
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 ?
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.
Thanks,
-Sylvain
