Dear all, I'm glad to tell everyone that we finally succeeded to build Devstack and run full tempest tests on it [1]. As the test build result shows [2], the job is stable enough to run. For earlier 13+ job results. (will do more recheck later) One Timeout, and two failure cases (Which are targeted by increase `BUILD_TIMEOUT` to 900 secs). The job `devstack-platform-arm64` runs around 2.22 hrs to 3.04 hrs, which is near two times slower than on x86 environment. It's not a solid number as the performance might change a lot with different cloud environments and different hardware. But I think this is a great chance for us to make more improvements. At least now we have a test job ready (Not merged yet) for you to do experiments with. And we should also add suggestions to Multi-arch SIG documentation so once we make improvements, other architecture can share the efforts too. *So please join us if you are also interested in help tuning the performance :)* *Also, we need to discuss what kind of way we should run this job, should we separate it into small jobs? Should we run it as a periodic job? voting?* *On the other hand, I would hope to collect more ideas on how we should move forward.* *Please provide your idea for this on our Xena PTG etherpad* *https://etherpad.opendev.org/p/xena-ptg-multi-arch-sig <https://etherpad.opendev.org/p/xena-ptg-multi-arch-sig>* Our PTG is scheduled around 4/20 Tuesday from 07:00-08:00 and 15:00-16:00 (UTC time) If you plan to join our PTG, feel free to update our PTG etherpad to suggest other topics.
