-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@v2.1`, the `v2.1` 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`

-
-
-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 one stage, 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:
-
-* Quartz: Intel bi-socket x86
-* Lassen: Power9 + Nvidia GPU
-* Corona: AMD 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
-
-Each file is this directory is the root configuration file for one
-sub-pipeline. The naming reflects the corresponding couple (`machine`,
-`test_type`).
-
-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 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 quartz for example resumes to:
-
-```yaml
-<job_name>:
-  variables:
-    SPEC: "<spack_spec>"
-  extends: .build_and_test_on_quartz
-```
-
-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.

-### 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 Docker
-
-We provide a [Dockerfile.base](Dockerfile.base) to build an ubuntu base image,
-and a [Dockerfile](Dockerfile) to build a smaller one with a multi-stage build.
-You can use this image for a demo of using mfem! 🎉️
-
-Updated containers are built and deployed on merges to the main branch and releases.
-If you want to request a build on demand, you can [manually run the workflow](https://docs.github.com/en/actions/managing-workflow-runs/manually-running-a-workflow) thanks to the workflow dispatch event.
-
-### Usage
-
-Here is how to build the container. Note that we build so it belongs to the same
-namespace as the repository here. "ghcr.io" means "GitHub Container Registry" and
-is the [GitHub packages](https://github.com/features/packages) registry that supports
- Docker images and other OCI artifacts. From the root of the repository:
-
-```bash
-$ docker build -f config/docker/Dockerfile -t ghcr.io/mfem/mfem-ubuntu .
-$ docker build -f config/docker/Dockerfile.base -t ghcr.io/mfem/mfem-ubuntu-base .
-```
-
-### Shell Ubuntu
-
-To shell into the container:
-
-```bash
-$ docker run -it ghcr.io/mfem/mfem-ubuntu
-```
-
-This smaller image has a view where everything is installed.
-
-```bash
-$ ls
-bin  etc  include  lib  libexec  sbin  share  var
-```
-
- - Examples are in share/mfem/examples
- - Examples are in share/mfem/miniapps
-
-You can read more about interaction with these examples and miniapps below.
-
-### Shell Ubuntu Base
-
-To shell into the container:
-
-```bash
-$ docker run -it ghcr.io/mfem/mfem-ubuntu-base bash
-```
-
-Off the bat, you can see mfem libraries are in your path so you can jump into development:
-
-```bash
-env | grep mfem
-```
-```bash
-PKG_CONFIG_PATH=/opt/mfem-env/.spack-env/view/lib/pkgconfig:/opt/mfem-env/.spack-env/view/share/pkgconfig:/opt/mfem-env/.spack-env/view/lib64/pkgconfig
-PWD=/opt/mfem-env
-MANPATH=/opt/mfem-env/.spack-env/view/share/man:/opt/mfem-env/.spack-env/view/man:
-CMAKE_PREFIX_PATH=/opt/mfem-env/.spack-env/view
-SPACK_ENV=/opt/mfem-env
-ACLOCAL_PATH=/opt/mfem-env/.spack-env/view/share/aclocal
-LD_LIBRARY_PATH=/opt/mfem-env/.spack-env/view/lib:/opt/mfem-env/.spack-env/view/lib64
-PATH=/opt/mfem-env/.spack-env/view/bin:/opt/view/bin:/opt/spack/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin
-```
-
-#### Examples and MiniApps
-
-If you want to develop a tool that _uses_ mfem, you can find the built libraries in:
-
-```
-$ ls /opt/mfem-env/.spack-env/view/
-bin  etc  include  lib  libexec  sbin  share  var
-```
-
-And yes, this is the working directory when you shell into the container!
-You can find the examples here:
-
-
-```bash
-cd share/mfem/examples
-```
-```bash
-$ ./ex0
-Options used:
-   --mesh ../data/star.mesh
-   --order 1
-Number of unknowns: 101
-   Iteration :   0  (B r, r) = 0.184259
-   Iteration :   1  (B r, r) = 0.102754
-   Iteration :   2  (B r, r) = 0.00558141
-   Iteration :   3  (B r, r) = 1.5247e-05
-   Iteration :   4  (B r, r) = 1.13807e-07
-   Iteration :   5  (B r, r) = 6.27231e-09
-   Iteration :   6  (B r, r) = 3.76268e-11
-   Iteration :   7  (B r, r) = 6.07423e-13
-   Iteration :   8  (B r, r) = 4.10615e-15
-Average reduction factor = 0.140201
-```
-
-Try running a few, and look at the associated .cpp file for the source code!
-You can also explore the "mini apps," also in share/mfem, but under miniapps.
-
-```bash
-# This is run from the examples directory
-$ cd ../miniapps
-```
-```bash
-$ ls
-CMakeLists.txt  common            meshing  nurbs        shifted  toys
-adjoint         electromagnetics  mtop     parelag      solvers
-autodiff        gslib             navier   performance  tools
-```
-
-And an example in "toys"
-
-```bash
-cd toys
-```
-```bash
-$ ./automata -no-vis
-Options used:
-   --num-steps 16
-   --rule 90
-   --no-visualization
-
-Rule:
- 111 110 101 100 011 010 001 000
-  0   1   0   1   1   0   1   0
-
-Applying rule...done.
-```
-
-Have fun!
-
-
-#### Your own App
-If you want to develop with your own code base
-(and mfem as is in the container) you can bind to somewhere else in the container (e.g., src)
-
-```bash
-$ docker run -it ghcr.io/mfem/mfem-ubuntu-base -v $PWD:/src bash
-```
-
-In the above, we can pretend your project is in the present working directory (PWD) and we are
-binding to source. You can then use the mfem in the container for development, and if you
-want to distribute your library or app in a container, you can use the mfem container as the base.

-This directory contains recommended git hooks, which are scripts that can be
-used to improve your development experience with MFEM:
-
-### The hooks
-
-* `pre-commit` is a hook that will be applied before each commit and run
-`astyle` on the code. This will ensure that your changes comply with the MFEM
-code styling guidelines.
-
-* `pre-push` is a hook that will be applied before each push to run a quick set
-of tests that verify that your files headers are in compliance, and that you did
-not add any large files to the repo.
-
-### Setup
-
-To setup the git hooks, run `make hooks`, which creates symlinks to the hooks in
-the `.git/hooks` directory. Individual hooks can be enabled by manually creating
-symlinks.
-
-(You may also copy the scripts directly and customize them further, but this way
-you may miss additional updates in the future.)
-
-### Failures
-
-The `branch-history` check can fail in some cases when the history is OK. For
-example, when a large number of files were modified for a legitimate reason, or
-when a picture was added for documentation.
-
-If that is the case, make sure the failure is indeed justified, and rerun the
-push command with the `--no-verify` option. This will skip the hooks, allowing
-you to push those changes.
