Thanos PR merged (https://github.com/vacp2p/10ksim/pull/15) - Create class to manage data (https://github.com/vacp2p/10ksim/pull/16). - hardware offloaded for Waku testing - Built 24 new Kubernetes workers, configured them with static IPs and all tuning - Got new CX6 cards updated, configured, installed and working - Achieved hardware offloading; but: - Running a Waku workload, two interesting things happened - When we started the publisher, the load increased until the physical nodes become so unusably slow that they needed IPMI intervention to come back to life - Checking the offloadeded flows during the test (prior to publishing) showed no offloaded routes or flows. - We need to figure out how to get our workload offloaded correctly. ### vac:qa: - `waku:test-automation-sharding` -
