From d36197266a107d4d44fe1fdc65636782bc78776b Mon Sep 17 00:00:00 2001 From: Lup Yuen Lee Date: Thu, 12 Sep 2024 21:28:01 +0800 Subject: [PATCH] build.yml: Limit the GitHub Runners This PR modifies NuttX CI and GitHub Actions, to comply with ASF Policy. Right now, every NuttX Pull Request will trigger 24 Concurrent Jobs (GitHub Runners), executing them in parallel: https://lupyuen.github.io/articles/ci According to ASF Policy: We should run at most 15 Concurrent Jobs: https://infra.apache.org/github-actions-policy.html Thus we'll cut down the Concurrent Jobs from 24 down to 15. That's 12 Linux Jobs, 2 macOS, 1 Windows. (Each job takes 30 mins to 2 hours) (1) Right now our "Linux > Strategy" is a flat list of 20 Linux Jobs, all executed in parallel (2) We change "Linux > Strategy" to prioritise by Target Architecture, and limit to 12 concurrent jobs (3) So NuttX CI will initially execute 12 Build Jobs across Arm32, Arm64, RISC-V, Simulator and Xtensa. As they complete, NuttX CI will execute the remaining 8 Build Jobs (for Arm32). (4) This will extend the Overall Build Duration from [2 hours](https://github.com/apache/nuttx/actions/runs/10817443237) to [2.25 hours](https://github.com/lupyuen4/ci-nuttx/actions/runs/10828246630) (5) We'll also limit macOS Jobs to 2, Windows Jobs to 1 --- .github/workflows/build.yml | 9 ++++++++- 1 file changed, 8 insertions(+), 1 deletion(-) diff --git a/.github/workflows/build.yml b/.github/workflows/build.yml index e52e55efb2..1f88c4cc51 100644 --- a/.github/workflows/build.yml +++ b/.github/workflows/build.yml @@ -122,8 +122,13 @@ jobs: DOCKER_BUILDKIT: 1 strategy: + max-parallel: 12 matrix: - boards: [arm-01, arm-02, arm-03, arm-04, arm-05, arm-06, arm-07, arm-08, arm-09, arm-10, arm-11, arm-12, arm-13, other, risc-v-01, risc-v-02, sim-01, sim-02, xtensa-01, xtensa-02] + boards: [ + arm-01, other, risc-v-01, sim-01, xtensa-01, + arm-02, risc-v-02, sim-02, xtensa-02, + arm-03, arm-04, arm-05, arm-06, arm-07, arm-08, arm-09, arm-10, arm-11, arm-12, arm-13 + ] steps: - name: Download Source Artifact @@ -178,6 +183,7 @@ jobs: runs-on: macos-13 needs: Fetch-Source strategy: + max-parallel: 2 matrix: boards: [macos, sim-01, sim-02] steps: @@ -225,6 +231,7 @@ jobs: runs-on: windows-latest strategy: fail-fast: false + max-parallel: 1 matrix: boards: [msys2]
