Hello Fedor @ Cirrus CI, CC: Ruby Core mailing list. Thank you for helping the Ruby project for adding Cirrus CI. I am sending an email to ask you for help to improve the Cirrus CI. We are running 4 parallel jobs (2 gcc cases ARM, 2 clang cases ARM) in the Cirrus CI. However, I am seeing some challenges such as the queue is stopping, and the clang cases are 2 or 3 times slower than gcc cases. So, today we stopped the 2 clang cases in a compromised way. Could you check our .cirrus.yml file on the reverted commit, and give advice to us and ideally just send a pull-request to the master branch for that? https://github.com/ruby/ruby/blob/master/.cirrus.yml ``` $ git clone https://github.com/ruby/ruby.git $ cd ruby $ git revert 72f07f0a5f882e87e305d668587152fa209a0568. ``` I suspect the current `cpu:` value might not be correct. And we may need the following change. ``` diff --git a/.cirrus.yml b/.cirrus.yml index be76e4ab4a..8b820be1a2 100644 --- a/.cirrus.yml +++ b/.cirrus.yml @@ -16,10 +16,10 @@ task: image: ghcr.io/ruby/ruby-ci-image:$CC # Define the used cpu core in each matrix task.
