Members of the French OpenStack community were invited to gather at EDF Lab
Paris-Saclay on May 22, 2024 for OpenInfra Day France 2024, one of many OpenInfra events organised all around Europe during May
and June. StackHPC both participated and was a silver-level sponsor of the event.
The day started with a plenary session of keynotes. After an introduction from
the organisers, Thierry Carrez, General Manager for the OpenInfra Foundation,
explained how OpenStack has recently seen renewed interest thanks to three main
factors:
- Digital sovereignty
- Migration away from VMWare, following its acquisition by Broadcom
- Investment in Accelerated Compute for AI
The Dawn supercomputer, in which StackHPC is involved, was highlighted as a major
OpenStack-based compute infrastructure for AI.
Several of the next keynotes and following talks presented use cases of
OpenStack clouds in France from the public and private sectors. One point that
came back multiple times was the use of Kolla Ansible to deploy OpenStack. As a
major contributor to the Kolla project, StackHPC is proud to be helping so many
organisations to successfully operate their OpenStack clouds.
Kayobe was also covered, with Léo
Gillot-Lamure describing how he uses it to deploy OpenStack on his home lab.
Continuing on the theme of accelerated compute, several talks focused on GPUs.
Erwan Gallen from Red Hat presented a good overview of all the different ways
to share access to NVIDIA GPUs (MIG, vGPU, etc.).
Sylvain Bauza, Nova PTL, presented the newest improvements for GPU devices in
OpenStack, in particular vGPU live migration and quota support. You can read
his slides
for more details.
Pierre Riteau from StackHPC presented our current work on Blazar, the OpenStack
reservation service, to improve sharing of GPU devices in private clouds.
Slides are available online.
We will share more details about these functionalities once merged upstream.
Another theme was feedback from operators about solving reliability and scaling
issues. Société Générale shared how they increased their instance creation
success rate by tuning Nova and Neutron parameters. OVH presented improvements
they made to RabbitMQ configuration to help it scale in large cloud regions.
Lastly, it is worth mentioning that the environmental impact of OpenStack
platforms was also among the concerns at this OpenInfra Day, with an
interesting talk on power management and energy efficiency given by Christophe
Fontaine from Red Hat.
This is just a sample of the talks given on the day. With three tracks in
parallel,
there was a lot more covered. Thank you to the organisers for putting this
great event together.
