-
-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 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.
-
-## `mfem-analysis.yml` (`build-analysis`)
-
-Checks if the code builds and satisfies minimal requirements.
-
-- `gitignore` builds hypre, METIS, and MFEM using `mfem/github-actions/build-hypre`, `mfem/github-actions/build-metis`, and `mfem/github-actions/build-mfem` and checks for correct `.gitignore` settings by running the `tests/scripts/gitignore` 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.
-
-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).

-  CUSTOM_CI_BUILDS_DIR: "/usr/workspace/mfem/gitlab-runner"
-
-##### PROJECT VARIABLES
-  USER_CI_TOP_DIR: "${CUSTOM_CI_BUILDS_DIR}/${GITLAB_USER_LOGIN}"
-  SHARED_REPOS_DIR: "${USER_CI_TOP_DIR}/repos"
-  AUTOTEST_ROOT: "${SHARED_REPOS_DIR}"
-  MFEM_DATA_DIR: "${SHARED_REPOS_DIR}/mfem-data"
-# AUTOTEST: enable (ON/YES) or disable (any other value) test reporting. See
-# also AUTOTEST_COMMIT.
-  AUTOTEST: "OFF"
-# AUTOTEST_COMMIT: used only when AUTOTEST is set to ON/YES.
-# * If AUTOTEST_COMMIT is set to ON/YES, reporting jobs will commit their
-#   files to the MFEM/autotest repo.
-# * If AUTOTEST_COMMIT is NOT set to ON/YES, reporting jobs will NOT commit

-
-
-This directory contains most of the GitLab CI configuration. MFEM runs both PR
-and nightly testing on GitLab.
-
-# Structure
-
-## Top level
-
-The root configuration file is `.gitlab-ci.yml` at the root of MFEM repo. This
-file only defines three stages, a prerequisites one, and two main stages in
-which we trigger several sub-pipelines.
-
-We use sub-pipelines to isolate the test for one combination of `machine`
-and `test type`.
-
-Machines typically include:
-
-* Dane: Intel Sapphire Rapids
-* Matrix: Intel Sapphire Rapids + Nvidia H100 GPU
-* Tioga: AMD MI250X GPU
-
-Test types include:
-
-* Build and test: Spack driven build of dependencies, mfem build, mfem
-  test
-* Baseline: Script driven build of dependencies, thorough testing
-
-⚠️ The sub-pipeline design allows to add a new machine or a new test type without
-altering the scheduling, execution and displaying of the others.
-
-## Sub-pipelines
-
-### build-and-test
-
-The build-and-test sub-pipelines leverage RADIUSS Shared CI to share most of
-the CI implementation. RADIUSS Shared CI provides a shared CI infrastructure
-vetted on most LC systems of interest and efficiently leveraging each machine
-scheduler to increase CI throughput. The maintenance of RADIUSS Shared CI is
-shared among several RADIUSS projects.
-
-Jobs for the build-and-test sub-pipelines are defined in the jobs directory.
-Because build-and-test jobs leverage Uberenv and Spack to build the
-dependencies automatically, the jobs essentially consists in a `spack spec`
-defined in the jobs files, and some scheduling parameters defined in the
-`.gitlab/custom-jobs-and-variables.yml` file.
-
-Build-and-test jobs all run the `tests/gitlab/build_and_test` script.
-
-The build-and-test pipelines are controlled by the
-`.gitlab/subscribed-pipelines.yml` which defines which machines to run on and
-implements additional features like machine availability check, and job list
-generation.
-
-### baseline
-
-Baseline sub-pipelines are described by files with names reflecting the
-machine it runs on, e.g. `dane-baseline`.
-
-Those files define the *stages* and the *jobs* for the sub-pipeline. They
-also contain any configuration that cannot be shared. For the most part
-though, the configuration is shared and is placed in `.gitlab/configs`.
-
-We try to keep scripts out of the CI config and share them among similar
-jobs. They are gathered in `.gitlab/scripts`.
-
-## Scripts
-
-Scripts specific to the CI only are in `.gitlab/scripts`. It is best practice
-to keep scripts outside the CI configuration (no bash scripts embedded in a
-yaml file) because it helps with readability, maintenance and also with
-transition to another CI system.
-
-⚠️ Most of the scripts there are driven by environment variables and do not have a
-usage function. This should be improved.
-
-
-# More testing
-
-## Adding a new target to a build-and-test pipeline
-
-`build-and-test` pipelines rely on Spack to install dependencies. Spack is
-driven by Uberenv which helps freezing Spack configuration: the goal being to
-point to a specific commit in Spack and isolate its configuration so that it is
-not influenced by the user environment. More documentation about this can be
-found in `tests/gitlab`.

-In the end, the MFEM target for which to build the dependencies is expressed
-with a spack spec of MFEM, within the limits permitted by the MFEM spack
-package.
-
-In any build-and-test sub-pipeline a job basically consists in defining the
-spack spec to use. Adding a job on Dane for example resumes to:
-
-```yaml
-<job_name>:
-  variables:
-    SPEC: "<spack_spec>"
-  extends: .job_on_dane
-```
-
-The remaining and non trivial work is to make sure this spec is working. To
-test a spec before adding it, or reproduce a CI configuration, please refer to
-`tests/gitlab/reproduce-ci-jobs-interactively.md`.
-
-⚠️ It is assumed that the spack spec applies to `mfem@develop`. That's why in the
-CI all the specs start with the compiler or the variants to apply to mfem. The
-mechanism still works with a full spec.

-# 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.
-
-## Attribution

-version 2.1, available at
-[https://www.contributor-covenant.org/version/2/1/code_of_conduct.html][v2.1].

-### MFEM PR Rules
-
-The Pull Request (PR) approval process in MFEM is similar to the approval of papers in a peer-reviewed journal. In particular:
-
-1. There is an MFEM board of "editors" that evaluates new PRs and assigns "reviewers" for each PR.
-
-2. The assigned reviewers are responsible to carefully review and test the proposed PR.
-
-3. A PR can be (manually) merged in the *next* branch only if 2 of the assigned reviewers have approved it and it has passed internal testing. This merge can be performed by any of the assigned reviewers or by any of the editors.
-
-4. A PR can be merged in the *master* branch only if it has been tested successfully for a week in *next* and an editor has (optionally) taken a final look. This merge can be performed only by one of the editors.
-
-#### Responsibilities of Editors
-
-The current list of MFEM editors is:
-
-- [@v-dobrev](https://github.com/v-dobrev) (Veselin Dobrev)
-- [@tzanio](https://github.com/tzanio) (Tzanio Kolev)
-- [@pazner](https://github.com/pazner) (Will Pazner)
-- [@mlstowell](https://github.com/mlstowell) (Mark Stowell)
-
-**The responsibilities of the editors are:**
-
-1. To assign appropriate milestone and labels for new PRs, e.g. *bugfix*, *minor*, *api-change*, *high-impact*, etc.
-
-2. To assign at least 2 reviewers for new PRs. An editor can also be a reviewer. The editor, reviewers, and author should be listed as "Assignees" on the GitHub PR page. After assignment, the `in-review` label should be added.
-
-3. To complete the initial PR evaluation and assignments in a timely manner: 1 week from submission.
-
-4. To assist reviewers when they need help with their reviews (but also to stay out of the way when they don't).
-
-5. To remind the reviewers about timely completion of their review.
-
-6. To take a final look and complete the PR merge in *master*. The final look step is optional and shouldn't take more than 3 days.
-
-7. The assignment of bugfixes should be expedited proportional to their importance, e.g. in some cases the editor can assign much shorter review window.
-
-#### Responsibilities of Reviewers
-
-Everyone on the MFEM team can be asked to serve as a reviewer on a PR in their area of expertise.
-
-**The responsibilities of the reviewers are:**
-
-1. To let the editors know if the proposed assignment is not a good match for them.
-
-2. To communicate with the PR author, provide feedback and work with them to resolve issues.
-
-3. To ensure the quality of the PR by making sure that the code adheres to the [Developer Guidelines](#developer-guidelines), e.g. all methods, data members, and functions have documentation, including data ownership and lifetime, new examples/miniapps have a corresponding PR in mfem/web, major features have `CHANGELOG` entries, etc.
-
-3. To seek help from the editors in case of difficulties.
-
-4. To complete the review in a timely manner: 3 weeks from assignment.
-
-5. To test the PR thoroughly before merging in *next*. The PR author is also encouraged to perform testing and inform the reviewers about the results.
-
-6. To monitor the PR impact on the testing in the *next* branch and alert the editors that the PR is ready for merging in *master*.
-
-7. The review of bugfixes should be expedited proportional to their importance. The review window can be much less than three weeks in such cases.
-
-#### Responsibilities of Authors
-
-Authors should clearly indicate when a PR is ready for review (before that the PR should be marked as `Draft` or `[WIP]`).
-
-**The responsibilities of the authors are:**
-
-1. To follow the instructions and PR checklist in the `CONTRIBUTING.md` document in the MFEM repository.
-
-2. To respond to reviewer feedback in a timely manner.
-
-3. Authors are encouraged to perform testing and inform the reviewers about the results.
-
-4. Authors can use the "Reviewers" section of the GitHub PR page to suggest reviewers, but the "Assignees" section will show who the editor has assigned to do the reviews.
-
-5. To indicate when the PR is ready for review by adding the `ready-for-review` label.

-MFEM expects the `ROCM_PATH` environment variable to be set to the path of the
-ROCM install, as well as having `$ROCM_PATH/bin` in `PATH`.
-
-Specific options for RAJA+HIP+MPI
-=================================
-RAJA uses CMake's built-in HIP support (added in CMake 3.21), while MFEM uses
-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".
