From b2e8b67e34467f4e631e20e7b183cd13d58fccac Mon Sep 17 00:00:00 2001 From: Jimmy Chen Date: Fri, 6 Jun 2025 13:51:51 +1000 Subject: [PATCH] Reduce number of basic sim test nodes from 7 to 4 (#7566) Our basic sim test has been [flaky](https://github.com/sigp/lighthouse/actions/runs/15458818777/job/43515966229) for some time, and seems like it has gotten worse since electra fork was added to it in #7199. It looks like the github runner is struggling with the load, currently it runs 7 nodes on a 4 CPU runner, which is definitely too much. We could consider moving this to run on our self hosted runner - but I think running 7 nodes is unnecessary and we can probably trim test this down. Reduce number of basic sim test nodes from 7 (3 BN + 3 Proposer BN + 1 extra) to 4 (2 BN + 1 Proposer BN + 1 extra). If we want to run more nodes, we'd have to consider running on self hosted runners. --- testing/simulator/src/cli.rs | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/testing/simulator/src/cli.rs b/testing/simulator/src/cli.rs index 707baf04a7..1fa59df4fe 100644 --- a/testing/simulator/src/cli.rs +++ b/testing/simulator/src/cli.rs @@ -20,7 +20,7 @@ pub fn cli_app() -> Command { .short('n') .long("nodes") .action(ArgAction::Set) - .default_value("3") + .default_value("2") .help("Number of beacon nodes"), ) .arg( @@ -28,7 +28,7 @@ pub fn cli_app() -> Command { .short('p') .long("proposer-nodes") .action(ArgAction::Set) - .default_value("3") + .default_value("1") .help("Number of proposer-only beacon nodes"), ) .arg(
