From 146b4c7158c9ec1be4a759089035908fde1515b3 Mon Sep 17 00:00:00 2001 From: Gerard Gorman Date: Wed, 1 Oct 2025 14:10:01 +0100 Subject: [PATCH 1/2] ci: add ARM64 support with native builds and refactored workflows Add comprehensive ARM64 (linux/arm64) support for Devito's Docker images and CI/CD pipeline, enabling deployment on AWS Graviton, Apple Silicon, and other ARM64 platforms. Architecture & Build Strategy: - Native ARM64 builds on GitHub's free ubuntu-24.04-arm runners - Separate runners for each architecture (no cross-compilation) - x86_64 builds on ubuntu-22.04 (pinned to avoid ubuntu-latest migration) - Multi-platform Docker image support with proper manifest lists Workflow Improvements: - Refactor docker-bases.yml to use matrix strategy for GCC builds - Consolidate x86_64 and ARM64 base image builds into single job - Remove QEMU setup (not needed for native builds) - Add arm64 workflow dispatch input parameter - Conditional execution based on input flags to run only requested builds - ARM64 GCC limited to default version (building from source too slow) CI Test Coverage: - Add ARM64 test configurations to pytest-core-nompi.yml: - pytest-ubuntu-py312-gcc14-omp-arm64 - pytest-ubuntu-py311-gcc13-omp-arm64 - Add ARM64 MPI tests to pytest-core-mpi.yml (gcc-arm64) - Add ARM64 smoke test to docker-devito.yml - Pin x86_64 tests to ubuntu-22.04 for stability Bug Fixes: - Fix OpenMPI parallel build: change ${nproc} to $(nproc) in Dockerfile.cpu (reduces build time from ~15-20 mins to ~5-8 mins) - Add actionlint.yaml config for self-hosted runner label validation Documentation: - Add ARM64 section to docker/README.md - Document supported ARM64 platforms (AWS Graviton, Apple Silicon, etc.) - Add usage examples for ARM64 images --- .github/actionlint.yaml | 8 ++++ .github/workflows/docker-bases.yml | 58 ++++++++++++++++++++----- .github/workflows/docker-devito.yml | 6 +++ .github/workflows/pytest-core-mpi.yml | 15 +++++-- .github/workflows/pytest-core-nompi.yml | 18 +++++++- docker/Dockerfile.cpu | 2 +- docker/README.md | 41 +++++++++++++++-- 7 files changed, 127 insertions(+), 21 deletions(-) create mode 100644 .github/actionlint.yaml diff --git a/.github/actionlint.yaml b/.github/actionlint.yaml new file mode 100644 index 0000000000..cad0086b06 --- /dev/null +++ b/.github/actionlint.yaml @@ -0,0 +1,8 @@ +# actionlint configuration file +# https://github.com/rhysd/actionlint/blob/main/docs/config.md + +self-hosted-runner: + # Custom labels for self-hosted runners + labels: + -
