    • However, network connection not yet working. Comments appreciated.
    • Baptiste Comment: To be honest, going through Windows is a big added complexity to the setup. I would recommend installing an Ubuntu/Debian dual-boot and running QEMU (+ libvirt) from there if network problems persist. CUDA/GPU support should be solid on Ubuntu.
  • Lab Updates - hardware changes at Colo Nov.11/12 2019. Currently no known facility to host water-cooled nodes.
  • Tensorflow script has been documented - comments appreciated - Building TensorFlow on AArch64
    • Problems with NumPy building. Bug appears in OpenHPC and RedHat. Perhaps consider fetching latest toolchain builds from Linaro Toolchain team.
  • Futurewei hosting - How does affect 'EAR' restrictions for technology transfer if we login to a Futurewei hosted system?
  • Compiler Updates - Open
    • LLVM updates continuing for A64FX by Fujitsu under NDA.
    • GCC updates for A64FX - there are currently no Fujitsu resources. Non-NDA resources cannot be used until the A64FX technical specification is made available.
    • A64FX specification 'may' be released 1Q2020.
