vac:dst: §

• wakurtosis:vac:retrospective-rlog
  • Reviewed comments; soon to publish
• wakurtosis:vac:rlog
  • Analysis of new Wakurtosis simulations regarding the 600 nodes anomaly
  • Analysis of K8 simulations regarding the 600 nodes anomaly

  • Run 600 nodes NWaku Shadow simulations with and without load
• analysis:nomos:simulation-analysis
  • The network delay/bandwidth tuning, readjusting the probabilities, none of them helped. The bug(s) cannot be side-steped in any meaningful way.
  • New issue: for > 10 views, the disk usage blows up. 1.7 TERABYTES; and the output is just text files! This was quite unexpected; we now have yet another scalability issue with the nomos sim.
  • spent couple of days on the Rust code and worked on adjustments. None of them helped with the bug.
• analysis-gsub-model:vac:refactoring
  • Tuned/cleanedup to the control messages code

    • It’s actually expected behaviour.
    • Issue
  • bug: Filter doesn’t receive messages after subscribing and restarting
    • Issue
