+
+------------
+
+1) Confirm quorum
+
+No quorum.
+
+2) Secretary
+
+Secretary is Dan Bailey.
+
+3) PR1971
+
+A bug was discovered with vdb_tool that wasn't caught with CI. This has now been
+addressed and the CI extended to test this case.
+
+4) Binary Distribution
+
+Brief discussion about binary distribution. Still want to support package
+manager maintainers, but hesitant to take this on ourselves. A bigger ROI might
+be to focus our efforts on migrating towards CMake config files to make using
+OpenVDB as a dependency easier. The autogenerated version.h is a step in that
+direction, but could be improved with CMake configs. Other ASWF projects such
+as OpenEXR have successfully gone in this direction.
+
+Anaconda integration has been attempted, but is challenging as it only supports
+a single library per module by default.
+
+5) PR1977
+
+Dhruv has submitted this PR to address issues with compiling OpenVDB using Clang
+19. This new version is stricter and is catching a few valid issues.
+
+6) Fluid Example
+
+All would like this to go in. Andre says that it is blocked on an issue with the
+Poisson solver which needs to be resolved. Also, the OpenVDB Remove Divergence
+SOP has a bug in how the matrices are initialized that needs to be addressed.
+
+There is a new NanoVDB poisson solver which is of interest to the group. All
+agreed that it would potentially be a good fit for NanoVDB. Dan would also
+like an example of how to call it directly from OpenVDB.
+
+7) TBB Threading
+
+Question about our use of TBB (#1973). Previously discussed making TBB optional
+by wrapping all the data structures and function calls in
+openvdb/util/Threading.h. This could provide a route to running
+single-threading or providing another threading implementation like Apple's
+Grand Central Dispatch. A lot of work needed and not clear how general this
+approach would be.
+
+8) ASWF Code Build
+
+Jonathan to reach out to CI working group to try and move this forward to get
+GPU runtime testing. Ken can escalate to TSC if need be.
+
+9) Next meeting
+
+Next meeting is Tuesday December 17, 2024 at 11:00 PST. This will be the last
+meeting of the year.
