Action Items

Minutes

  • Project updates

    • System Ready Compliant Platform Collaboration (SRCPC)

    • Big Data and Data Science (BDDS)

      • BigTop 3.3 release is being defined.

        • Rocky Linux support being discussed.

    • Tensorflow (TENS)

      • Tensorflow 2.16-rc0 is imminent.

      • There is a plan to use XLA as JAX's back end in the future. This might be good for us as XLA uses OneDNN, which uses ACL.

      • We are currently investigating some issues that only happen with GCC (only Linaro and Arm test GCC in the community). These issues are not affecting 2.16 upcoming release.

        • Static asserts are generating issues with GCC, but not with LLVM.

        • There is a problem with using GCC and Python 3.12.

    • Deploy CCA on Arm Platforms (DCAP)

      • Demo time: QEMU emulating an Arm platform with RME support as a host; host launching a Realm using QEMU inside it.

      • Build and execution instructions for the demo: Building an RME stack for QEMU.

  • UXL

    • Members to bring their pain points around UXL and what are the possible areas of collaboration on the topic.

  • Schedulers

    • In the beginning of the year, Andrea Righi, a Linux kernel engineer at Canonical, wrote about their experiments with a user space scheduler for gaming here.

    • Even though gaming is definitely not an area of interest for this group of people and, as a matter of fact, the proposal for a user space scheduler was rejected by the kernel community, I wonder if there are any pressing issues with schedulers that worries people here.

    • Linaro does have expertise in scheduler, having worked with power and performance improvements in this area in the past. There are also new, ongoing discussions in the Linaro Consumer Group about power and performance improvements for mobile workloads. And, even though power consumption is usually not a concern for data centers in general, I wonder if there is anything in the scheduler area that might be interesting for us to experiment or explore.

    • For instance, I remember from my old-company days that some heavy workloads usually have their own schedulers (e.g. databases). And, sometimes, machines were sold with very minimal operating system support just to run a specific workload.

    • Any virtualization specific needs for schedulers?

  • Events

  • AOB
