Dear all,
Over the past few days, we’ve been running multiple SONiC builds as part
of the SCOMB effort, and I spent some time stress testing the build process.
A few quick observations:
* The best speedup so far was with *16 parallel jobs*
* Build time was approximately *3 hours*
* A completely fresh build (no cached/pre-sourced images) takes around
*~5 hours*
Even with these optimizations, a build time of ~3 hours is not practical
for day-to-day development, particularly when multiple users are
iterating on builds. To support a more collaborative and efficient
workflow, this needs to be reduced further.
From what I’ve seen so far:
* There are likely *redundant packages and images* in the build
* Not everything included seems necessary for a *basic or iterative
build*
So a first step could be:
* Reviewing dependencies more critically
* Stripping down the build to only what’s actually required
That said, this is just an initial direction. There are likely better
approaches (e.g., caching strategies, registry mirroring, incremental
builds), so it would be great to get more input.
If you have suggestions, please share them here:

Also, feel free to pick up any open tickets if something looks interesting.
Best regards,
Rankan Sen

Hey everyone,
I am very excited to announce our *second ALASCA community Hackathon*.
We are inviting you all to join us on *July 1st and 2nd in Stuttgart at
Urban Spaces* (https://urbanspaces.de/de) to get together again and
spend 2 days working on and further advancing the assisting projects as
well as related topics within ALASCA! We are planning on doing full day
hacking sessions for thpse 2 days. On top of that, all Hackathon
participants are invited to join our *member UhuruTec's summer party in
the evening on day 1*, so we are all set for a great evening event.
Since we are currently working on *SCOMB *and trying to set up the SONiC
Community Build, I was thinking that that would be a perfect chance for
us to get together in person and work towards that goal. If that is
something that you guys are interested in, we'd love it if you joined us
on July 1st and 2nd in Stuttgart.
If you'd like to participate, *please register for your free ticket* and
make sure to let us know if you'd like to stay for the evening event on
day 1. You can do so here: https://pretix.eu/focis/alasca-hackathon/ We
are really looking forward to get the chance to see everyone again!
Make sure to share the information regarding the Hackathon and extend
the invitation to your companies, communities and networks and everyone,
who'd like to contribute to SCOMB!
Greetings from Dresden
Helena

Hi Guys,
attached to this mail you'll find the meeting notes for our last call.
As a reminder: we have established action items to work on, which I have
now integrated into the ALASCA SCOMB Gitlab. Most of the issues don't
have people assigned to them yet, since not everyone has joint the
repository and not all task where taken by someone in our last call.
If you'd like to be included and want to start working on SCOMB with us,
please request access to join this repository
<https://gitlab.com/alasca.cloud/scomb>. You can also join our Matrix
channel
<https://matrix.to/#/!RbUuBLWOKNKYPHtFDF:matrix.org?via=matrix.org&via=matri…>
for the project.
Ideally, these issues will be our basis for progress tracking in our
montly calls. As of now, the issues I've created are not up to my
preferred standard yet and are missing some clear instructions and/or
expectations, which is due to the fact, that I don't fully understand
the material. Please bear with me, as I learn. ☺️
Feel free to join the repository, grab tasks and let's get started!
Please also feel free to add your own issues if you think of any or
specify the ones I have added with more detailed information.
Thanks for your support!
Greetings
Helena

Hello Rankan,
thanks for your quick reply. Currently we won't build SONiC because
installation date is too close now (next week), however please let us know
once community build with MLAG support is available - we will give it a try
with our next cluster installed.
Thanks,
Martin
