Minutes

• Data Center Group project updates
  
  • Etcd
    • Arm is now a tier 1 supported platform. Etcd maintainers will take care of it.
  • SystemReady Compliant Platform Collaboratio (SRCPC)
    • Shashi will provide latest updates.
  • 
  •  
    • Due to our priority on CCA work, Shashi will focus on CCA work to help make progress quicker there. This project will continue, as Marcin Juszkiewicz (Deactivated), a Red Hat assignee into Linaro, will continue the work.
  • Confidential Computing on Realms (CCR)
    • Arm requested a change to the name of the project in order to avoid confusion and to make sure that the work we are doing is very well synchronized with the CCA work.
    • The project will be renamed to Deploy CCA on Arm Platforms (DCAP).
    • Work ongoing in the reproduction of Arm's environment with FVPs.
    • From a management perspective, we are digging deeper into Veraison and how the attestation verification service it provides integrates with other part of the software stack, specially with Confidential Containers (CoCo).
  • Tensorflow
    • Finishing latest bugs before 2.14 branch cut. Release will happen probably before end of August.
    • Close to 2.14 there will be a 2.15 with the goal to introduce clang 17 as the official tool chain for Tensorflow. AArch64 is still built with gcc because there are 5 unit tests failing when building with clang 16. Andrew is investigating these issues.
  • Big Data and Data Science (BDDS)
    • Investigating some performance issues in Hadoop and Spark. The Spark issues are pointing to potential performance issues on OpenBLAS. Investigating.
  • STOR
    • Ceph
      • OpenEuler support introduced. Ceph can be natively built in OpenEuler and there is a remote CI running.
    • Lustre
      • CI was set up and new errors related to file system check were found. Next step is to investigate these bugs.
      • OpenEuler latest LTS release includes Lustre packages.

• Arm Interstellar project
  • Leonardo Garcia wasn't able to find out the list of projects / libraries that Arm is working on. Still investigating.
