-# MFEM Pull Request Review Agent Guide
-
-## Purpose and scope
-Review MFEM PRs for correctness, maintainability, performance, portability, test coverage, and MFEM consistency. Use the diff and PR context; reference source files, tests, and CI results when available. Follow `CONTRIBUTING.md`, especially Developer Guidelines, PR rules, checklist, and testing.
-
-## Critical review pillars
-- Correctness and numerical behavior
-- API and user-facing impact
-- Performance implications
-- Maintainability and portability
-
-## Review workflow
-1. Read the PR description, linked issues, and intended behavior.
-2. Inspect the diff before commenting.
-3. Identify affected MFEM components, examples, tests, build or docs changes, and downstream APIs.
-4. Analyze the code against the critical review pillars.
-5. Compare the change against nearby code and MFEM patterns; flag unmotivated deviations.
-6. Check whether tests and documentation were updated appropriately.
-7. Review CI results and suggest actions.
-8. Produce a structured review with prioritized findings.
-9. Always limit conclusions to available evidence.
-
-## MFEM-specific review checklist
-- Component-aware scope: identify the touched subsystem (FEM, solvers, preconditioners, linear algebra, mesh, examples, miniapps, build, or docs) and assess its impact against the review pillars.
-- Numerical and algorithmic behavior: assess issues in convergence, stability, tolerances, precision, iteration limits, and failure handling. If clear opportunities exist to improve the algorithmic approach, call them out with expected impact.
-- API and user-facing impact: assess backward compatibility, user-visible behavior and default changes, migration impact, deprecations, and whether documentation clearly explains user-facing API changes.
-- Data structure and memory semantics: assess ownership, lifetime, aliasing, container behavior, and device-host synchronization.
-- Parallel and serial behavior: assess whether the change preserves equivalent semantics in serial and parallel modes where applicable; if logic is currently mode-specific, check whether extension to the other mode is straightforward (clear abstractions, no hard-wired assumptions), document constraints, and call out expected behavior differences explicitly.
-- Backend and portability impact: assess likely cross-backend risks in CPU, CUDA, HIP, OCCA, RAJA, partial assembly, fallback paths, compiler compatibility, and platform assumptions.
-- Build, dependency, and configuration impact: assess CMake or make changes, optional dependency behavior, and feature-flag interactions.
-- Tests and docs alignment: check available regression or unit coverage evidence for changed behavior, and ensure docs are updated for new flags, APIs, options, or behavior changes.
-- MFEM developer-guideline fit: keep code lean, simple, general, logically separated, and portable; suggest C++17 improvements when they clearly improve safety, clarity, or maintainability.
-- New source files, examples, or miniapps: if a PR adds source/header files, verify they are properly wired into the relevant `makefile` and `CMakeLists.txt`, referenced in docs where applicable (including `doc/CodeDocumentation.dox`), and added to top-level `.gitignore` only when generated artifacts require it.
-- Changelog: verify `CHANGELOG` is updated if the PR introduces significant new features or user-facing changes.
-- MFEM conventions: use `real_t`; use `mfem::out`/`mfem::err` instead of `std::cout`/`std::cerr` in library code; flag large/binary files; if AI assistance is apparent but undisclosed, suggest following `CONTRIBUTING.md`.
-- Edge cases: if the PR touches complex or error-prone areas, suggest additional tests for edge cases, failure modes, and parallel behavior.
-
-## Commenting guidelines
-- Keep comments concise, actionable, and grounded in the diff.
-- Focus on correctness, behavior changes, and user impact over style nits.
-- Be professional, concise, collaborative, technically precise, and avoid unsupported assumptions.

-
-This directory contains the GitHub CI scripts for MFEM.
-
-Note that some of these scripts use the shared MFEM GitHub Actions from the external mfem/github-actions repository:
-
-  <https://github.com/mfem/github-actions>
-
-For a particular action, e.g. `mfem/github-actions/build-mfem@v2.5`, the `v2.5` suffix denotes the branch (or tag) in the above from which the action is taken.
-
-The current CI workflows are:
-
-## `repo-check.yml`
-
-Runs a number of static repository-level sanity checks.
-
-- `file-headers-check` checks copyright date, license, etc. using the `--copyright`, `--license` and `--release` options of the `config/githooks/pre-push` script.
-
-- `code-style` checks the code style using the `--style` option of the `config/githooks/pre-push` script.
-
-- `documentation` checks the documentation build using the `tests/scripts/documentation` script.
-
-- `branch-history` guards against accidental commits of large files using the `--history` option of the `config/githooks/pre-push` script.
-
-## `builds-and-tests.yml`
-
-Runs a matrix of builds and tests runs with different compilers, OS, mfem/hypre settings, etc. Also processes and upload Codecov reports.
-
-One matrix job runs `tests/scripts/gitignore` after `make test-noclean` to check generated artifacts against `.gitignore`.
-
-Uses the following GitHub Actions from <https://github.com/mfem/github-actions>:
-
-- `mfem/github-actions/build-hypre`
-- `mfem/github-actions/build-metis`
-- `mfem/github-actions/build-mfem`
-- `mfem/github-actions/upload-coverage`
-
-## Sanitizer Workflow for MFEM Verification
-
-This workflow validates MFEM unit tests, examples, and miniapps using sanitizer tools.
-
-- `sanitizers.yml` orchestrates:
-  - Building and caching dependencies: HYPRE, METIS, LSAN suppression file, and LLVM libcxx.
-  - Launching fine-grained jobs for serial (ASAN, MSAN, UBSAN) and parallel (ASAN, UBSAN) sanitizers.
-- `sanitize-tests.yml` is a reusable workflow accepting `par` mode (`true` for parallel) and `sanitizer` (ASAN, MSAN, or UBSAN) as inputs. It executes the following jobs:
-  - **Build**: Compiles the MFEM library with specified parallel and sanitizer settings.
-  - **Check**: Runs verification checks.
-  - Parallel jobs to test the following: **Examples**, **Miniapps** and **Unit tests**
-
-The workflow leverages composite actions in `.github/actions/sanitize/`:
-
-- `config`: Centralizes settings for the sanitizer workflow.
-- `mfem`: Manages the MFEM library build process.
-- `mpi`: Installs MPI and applies additional compilation flags.
-- `restore`: Restores the testing environment state.
-- `setup`: Builds or restores cached dependencies.

-# DESCRIPTION:
-###############################################################################
 # General GitLab pipelines configurations for supercomputers and Linux clusters
-# at Lawrence Livermore National Laboratory (LLNL).
-# This entire pipeline is LLNL-specific
-#
-# Important note: This file is a template provided by llnl/radiuss-shared-ci.
-# Remains to set variable values, change the reference to the radiuss-shared-ci
-# repo, opt-in and out optional features. The project can then extend it with
-# additional stages.
-#
-# In addition, each project should copy over and complete:
-# - .gitlab/custom-jobs-and-variables.yml
-# - .gitlab/subscribed-pipelines.yml
-#
-# The jobs should be specified in a file local to the project,
-# - .gitlab/jobs/${CI_MACHINE}.yml
-# or generated (see LLNL/Umpire for an example).

+# at Lawrence Livermore National Laboratory (LLNL). This entire pipeline is
+# LLNL-specific!
+
+
+# The pipeline is divided into stages. Usually, jobs in a given stage wait for
+# the preceding stages to complete before to start. However, we sometimes use
+# the "needs" keyword and express the DAG of jobs for more efficiency.
+# - We use setup and setup_baseline phases to download content outside of mfem
+#   directory.
+# - Allocate/Release is where quartz resource are allocated/released once for all.
+# - Build and Test is where we build and MFEM for multiple toolchains.
+# - Baseline_checks gathers baseline-type test suites execution
+# - Baseline_publish, only available on master, allows to update baseline
+#   results
+stages:
+  - sub-pipelines

-# MFEM Code of Conduct
-
-## Our Pledge
-
-We as members, contributors, and leaders pledge to make participation in our
-community a harassment-free experience for everyone, regardless of age, body
-size, visible or invisible disability, ethnicity, sex characteristics, gender
-identity and expression, level of experience, education, socio-economic status,
-nationality, personal appearance, race, caste, color, religion, or sexual
-identity and orientation.
-
-We pledge to act and interact in ways that contribute to an open, welcoming,
-diverse, inclusive, and healthy community.
-
-## Our Standards
-
-Examples of behavior that contributes to a positive environment for our
-community include:
-
-* Demonstrating empathy and kindness toward other people
-* Being respectful of differing opinions, viewpoints, and experiences
-* Giving and gracefully accepting constructive feedback
-* Accepting responsibility and apologizing to those affected by our mistakes,
-  and learning from the experience
-* Focusing on what is best not just for us as individuals, but for the overall
-  community
-
-Examples of unacceptable behavior include:
-
-* The use of sexualized language or imagery, and sexual attention or advances of
-  any kind
-* Trolling, insulting or derogatory comments, and personal or political attacks
-* Public or private harassment
-* Publishing others' private information, such as a physical or email address,
-  without their explicit permission
-* Other conduct which could reasonably be considered inappropriate in a
-  professional setting
-
-## Enforcement Responsibilities
-
-Community leaders are responsible for clarifying and enforcing our standards of
-acceptable behavior and will take appropriate and fair corrective action in
-response to any behavior that they deem inappropriate, threatening, offensive,
-or harmful.
-
-Community leaders have the right and responsibility to remove, edit, or reject
-comments, commits, code, wiki edits, issues, and other contributions that are
-not aligned to this Code of Conduct, and will communicate reasons for moderation
-decisions when appropriate.
-
-## Scope
-
-This Code of Conduct applies within all community spaces, and also applies when
-an individual is officially representing the community in public spaces.
-Examples of representing our community include using an official e-mail address,
-posting via an official social media account, or acting as an appointed
-representative at an online or offline event.
-
-## Enforcement
-
-Instances of abusive, harassing, or otherwise unacceptable behavior may be
-reported to the community leaders responsible for enforcement at mfem@llnl.gov.
-All complaints will be reviewed and investigated promptly and fairly.
-
-All community leaders are obligated to respect the privacy and security of the
-reporter of any incident. Anyone involved in the reported behavior will recuse
-themselves from the investigation and decision making about the resolution of
-the complaint.
-
-## Enforcement Guidelines
-
-Community leaders will follow these Community Impact Guidelines in determining
-the consequences for any action they deem in violation of this Code of Conduct:
-
-### 1. Correction
-
-**Community Impact**: Use of inappropriate language or other behavior deemed
-unprofessional or unwelcome in the community.
-
-**Consequence**: A private, written warning from community leaders, providing
-clarity around the nature of the violation and an explanation of why the
-behavior was inappropriate. A public apology may be requested.
-
-### 2. Warning
-
-**Community Impact**: A violation through a single incident or series of
-actions.
-
-**Consequence**: A warning with consequences for continued behavior. No
-interaction with the people involved, including unsolicited interaction with
-those enforcing the Code of Conduct, for a specified period of time. This
-includes avoiding interactions in community spaces as well as external channels
-like social media. Violating these terms may lead to a temporary or permanent
-ban.
-
-### 3. Temporary Ban
-
-**Community Impact**: A serious violation of community standards, including
-sustained inappropriate behavior.
-
-**Consequence**: A temporary ban from any sort of interaction or public
-communication with the community for a specified period of time. No public or
-private interaction with the people involved, including unsolicited interaction
-with those enforcing the Code of Conduct, is allowed during this period.
-Violating these terms may lead to a permanent ban.
-
-### 4. Permanent Ban
-
-**Community Impact**: Demonstrating a pattern of violation of community
-standards, including sustained inappropriate behavior, harassment of an
-individual, or aggression toward or disparagement of classes of individuals.
-
-**Consequence**: A permanent ban from any sort of public interaction within the
-community.

-the older HIP C++ library build/linkage. To ensure proper build and linkage
-check that `CMAKE_CXX_COMPILER` and `CMAKE_HIP_COMPILER` are set to the same
-compiler. This is especially important when using an MPI compiler (for example
-crayCC) where some linker flags may get dropped if these two are not identical.
-
-Specific options for Enzyme
-===========================
-To work properly, MFEM and Enzyme need to use the same LLVM/Clang configuration.
-For example, on macOS this can be done by using Homebrew: first install Enzyme,
-which in turn installs LLVM as a dependency (as of May 2025, this is LLVM 19):
-
-   brew install enzyme
-
-In order to ensure the correct compiler choice for the MFEM makefile build, set
-
-   CXX = $(shell brew --prefix llvm@19)/bin/clang++
-
-in the user.mk file (adapted from config/defaults.mk, see the section "Building
-with GNU make" above). With MPI, it is convenient to set
-
-   MPICXX = OMPI_CXX=$(CXX) mpicxx
-
-for OpenMPI and
-
-   MPICXX = MPICH_CXX=$(CXX) mpicxx
-
-for MPICH.
-
-Additionally, the Enzyme directory needs to be set in user.mk as follows:
-
-   ENZYME_DIR = $(shell brew --prefix enzyme)
-
-Specifically, a full build on a Mac can be tested by adding the following
-user.mk file in the config/ directory
-
-   MFEM_USE_ENZYME = YES
-   ENZYME_DIR = $(shell brew --prefix enzyme)
-   LLVM_DIR = $(shell brew --prefix llvm@19)
-   CXX = $(LLVM_DIR)/bin/clang++
-   MFEM_USE_MPI = YES
-   MPICXX = OMPI_CXX=$(CXX) mpicxx
-
-and running
-
-   make config
-   make -j
-   cd miniapps/dfem
-   make
-   ./dfem-minimal-surface
-
-On Linux systems, for example Ubuntu 24.04, use the package manager to install
-the Enzyme dependencies
-
-   sudo apt install libclang-dev libzstd-dev llvm-dev clang
-
-and then clone and build Enzyme
-
-   cd $HOME
-   git clone https://github.com/EnzymeAD/Enzyme.git
-   cd Enzyme/enzyme && mkdir build && cd build
-   CC=clang CXX=clang++ cmake .. -DLLVM_DIR=/usr/lib/llvm-18/lib/cmake -DCMAKE_INSTALL_PREFIX=$HOME/Enzyme/enzyme/build
-   make -j
-   make install
-
-From here, one can proceed in the same way using the following user.mk settings
-
-   MFEM_USE_ENZYME = YES
-   ENZYME_DIR = $(HOME)/Enzyme/enzyme/build
-   CXX = clang++
-   MFEM_USE_MPI = YES
-   MPICXX = OMPI_CXX=$(CXX) mpicxx
-
-On other Linux systems the LLVM packages may have different names, for example
-on RHEL9, one needs to "sudo yum install llvm-devel libzstd clang-devel".
