<h2>Highlights of the week</h2>
<h3><a
href="http://xlcloud.org/bin/view/Blog/Kwapi+an+energy+efficiency+architecture?language=en">Kwapi:
an energy efficiency architecture</a></h3>
<p>XLcloud HPC project focuses on providing high performance HPC
services, while improving energy efficiency. Kwapi makes a smart
use of data collected by Ceilometer interfaced with wattmeters
in order to introduce power consumption statistics in OpenStack
Nova scheduling strategies. Kwapi is stored on <a
href="https://github.com/stackforge/kwapi">StackForge</a> and
a blueprint is available <a
href="http://www.xlcloud.org/bin/view/XLcloudProjectManagement/EEA">here</a>.</p>
<h3><a
href="http://vmartinezdelacruz.com/logging-and-debugging-in-openstack/">Logging
and debugging in OpenStack</a></h3>
<p>The importance of debugging is much more noticeable on large
projects like OpenStack, which require both developers and
common users contribute and report when something is not going
well. In #openstack-101 <a href="http://vmartinezdelacruz.com/">Victoria
Martínez de la Cruz</a> met many people wanting to start
contributing to OpenStack, but a lot of them didn’t know how to
provide the right information to see where the problem was when
they were facing a blocker. A must read for anybody starting
(and a handy bookmark to provide to people stuck somewhere).</p>
<h3><a
href="http://julien.danjou.info/blog/2013/openstack-climate-capacity-leasing">Announcing
Climate, the OpenStack capacity leasing project</a></h3>
<p>A capacity leasing service is something really needed by
service providers, especially in the context of cloud platforms
dedicated to HPC style workload. Instead of building something
really specific, the decision has been made to build a new
standalone OpenStack components aiming to provide this kind of
functionnality to OpenStack. In the spirit of others OpenStack
components, it will be extensible to fullfil a large panel of
needs around this problematic.</p>
<h3><a
href="http://www.openstack.org/blog/2013/03/participate-in-the-first-openstack-user-survey/">Participate
in the first OpenStack User Survey!</a></h3>
<p>If you are an OpenStack user or have customers with OpenStack
deployments, please take 10 minutes to respond to our first User
Survey or pass it along to your network. Our community has grown
at an amazing rate in 2.5 years, and it’s time to better define
our user base and requirements, so we can respond and advocate
accordingly. <a href="http://awe.sm/r0NkC" target="_blank"><span

<h4><a
href="https://tropicaldevel.wordpress.com/2013/03/26/the-cost-of/"><b>The
Cost Of Client Side Image Downloads On the CPU</b></a></h4>
<p><a href="https://tropicaldevel.wordpress.com/">John Bresnahan</a>
discusses the importance of managing the resource consumption of
large file transfers. The NIC (and the network in general) is
always thought of as a consumable resource involved in a data
transfer. To a lesser extent the disk bandwidth is considered,
and on occasion the system bus is as well. However, the effects
on the CPU tend to be underestimated. John experimented a bit
and charted his results.</p>
