Past Meetings
=============

//Menu: sort children descending

Not all meetings gets summarized on this page. For example, there are no meeting
summaries at all available for 2010. This only means that there were not enough
things that needed deciding/documenting during these meetings to warrant someone
spending time on the task of writing a summary.

Anyone interested in Lumiera development is also encouraged to read mailing list
archives and other documentation.

8 May / 12 June 2024
--------------------
Discussion regarding the approach taken towards the next core topic, which
is how to structure the render nodes in the low-level model and how to perform
an invocation, leading to the calculation of media data. It is considered very
important for Lumiera to remain library / framework agnostic, even while we
use some frameworks and libraries for prototyping. The structure drafted over
the course of the last years and about to be integrated now must be flexible
enough to support adapt to the requirements of various libraries, _without
attempting to build a super structure_ to ``rule them all''.


13 Mar / 10 Apr 2024
--------------------
Status update and informal exchange regarding current development activities

 * after factoring out further external influences, a _breaking point_ for
   processing complex dependent schedules could be established, which closely
   matches theoretical expectations
 * a further measurement series (linear regression) was necessary to establish
   performance characteristics of the scheduler under constant high load
 * as expected, a serious weakness pertaining contention could be confirmed +
   (yet contention is not expected to be a problem in practice)
 * as mitigation, concurrency is scaled down on very short (100µs) jobs
 * overall we are confident that the new scheduler is capable to handle the
   expected load pattern and does not suffer from major (unknown) weaknesses.

Moreover, the problems related to integration and use of external frameworks
for video display were discussed further.

   Scheduler and discussion about methods of measurement.

************************
Most of our monthly developer meetings are informal discussions currently.
At times, there is only one developer working at the code, and thus there
is not much need for coordination. Sometimes, in-depth technical discussions
and decisions take place, and we'll publish at least an IRC transcript in
those cases; typically we also create a RfC to summarise the decisions.

.informal meetings, no summaries
********
In 2010, the monthly meetings where rather informal gatherings,
without any relevant decisions beyond the organisation of conference activities.
During that time, usually the two remaining Lumiera core developers where alternatively
either prevented by real-life obligations, or otherwise just in ``deep coding mode''
