vac:dst:

• eng-10ktool:vac:bandwidth-test
  • Delayed simulations.
  • Finished plotter module tests ready to review (https://github.com/vacp2p/10ksim/pull/19)
  • Finished data class, related PR already merged (https://github.com/vacp2p/10ksim/pull/16)
  • Improvements for scrapping, related and merged PRs (https://github.com/vacp2p/10ksim/pull/17 and https://github.com/vacp2p/10ksim/pull/18)
  • Investigate attacknet (https://twitter.com/ethPandaOps/status/1769773689979974006)
• eng-10ktool:vac:bandwidth-test
  • Many many fixes to get Kubernetes with OpenvSwitch + offloading + VMs working
    • Reinstalled 3 nodes with new Debian + Proxmox flavour
    • Installed Mellanox OFED drivers
    • Experimented with VirtIO network, managed to eventually get SR-IOV and Virtual Functions working
  • Waku - Benchmarked 1-worker (one worker as one eighth of a 64 core node) cluster
    • Indications are we can scale to ~14k nodes if scaling is linear, vs CPU usage observed on 1-worker
    • Had 243 Waku nodes, including publishing, running on the worker or 1/8th node with headroom to spare
    • Network offloading appears to about 2x as efficient CPU wise when running Waku
  • Further fixes for offloading setup once SR-IOV was working
  • Waku - Reinstalled 24 workers, then wiped them all and reinstalled 8 of them :(
  • Diagnosed incredibly complicated packet loss issues (which turned out to be caused by cloned VMs - note to self - clean up /etc/machine-id next time!)
  • Waku - Benchmarked 8-worker cluster (1 physical 64-core), scaled to 1200 nodes, hit major issue with Calico
    • Documented here - https://github.com/projectcalico/calico/issues/8676
  • Added caching to Harbor, further investigated removing Harbor rate limits
  • Discovered that adding multiple jobservice workers to Harbor makes rate limits higher
    • Deployed 6 jobservice workers in Harbor
  • Removed Vaxis and Nia from Kubernetes to help with CPU accounting since they host worker VMs
