-
-
-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.

 Version 4.3.1 (development)
 ===========================
- Added support for mesh preprocessing to resolve fine scale problem data
-  before simulation. This feature uses adaptive mesh refinement to control the
-  associated data oscillation error. See the new Example 30/30p.
-
- Switched from Artistic Style (astyle) version 2.05.1 to version 3.1 for code
-  formatting. See the "make style" target.
-
- Split the fem/fe.?pp files into separate files in the new fem/fe/ directory
-  to simplify and clarify the organization of FiniteElement classes.
-
 - Added support for hr-adaptivity using TMOP-based error estimator.

- Coefficient::SetTime now propagates the new time into internally stored
-  Coefficient objects.
-
- Added initial support for google-benchmarks in the tests/benchmarks directory.
-  It can be enabled with MFEM_USE_BENCHMARK=YES.
-
- Added Binder (mybinder.org) configuration files for C++ MFEM Jupyter Notebooks
-  with inline GLVis visualization as well as a new examples/jupyter/ directory
-  with a sample notebook based on Example 1. Implementation based on xeus-cling,
-  github.com/jupyter-xeus/xeus-cling + xeus-glvis, github.com/GLVis/xeus-glvis.
-
- Added 'double' atomicAdd implementation for previous versions of CUDA.
-
 - Adding lowest order Nedelec and Raviart-Thomas basis functions on wedge
  shaped elements.

- Gmsh meshes where all elements have zero physical tag (the default Gmsh
-  output format if no physical groups are defined) are now successfully loaded,
-  and elements are reassigned attribute number 1.
-
- Added new miniapps that use the ParELAG library, its hybrid smoothers, and the
-  hierarchy of spaces created by the element-based AMG (AMGe) methodology in
-  ParELAG to build multigrid solvers for H(curl) and H(div) forms. See the
-  miniapps/parelag directory for more details.
-
- Fixed several MinGW build issues on Windows.
-
- Remove the 'u' flag in the ar command, to update all files in the archive,
-  avoiding file name collisions from different subdirectories.
-
- Added initial TMOP-based capabilities for surface fitting and tangential
-  relaxation in the mesh-optimizer and pmesh-optimizer miniapps.

-### 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 (Veselin Dobrev)
- @tzanio (Tzanio Kolev)
- @pazner (Will Pazner)
- @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.

-[![Binder](https://mybinder.org/badge_logo.svg)](https://mybinder.org/v2/gh/mfem/mfem/master?filepath=examples%2Fjupyter%2Fex.ipynb)
-
-[xeus-cling](https://github.com/jupyter-xeus/xeus-cling) is a C++ Jupyter Kernel based on [cling](https://github.com/root-project/cling),
-which can be used to create interactive C++ MFEM and GLVis notebooks.
-
-Click on the `binder` button above for an interactive example.
-
-## Installing Locally
-
-In order to run notebooks locally you will need `xeus-cling` along with `mfem` and `xglvis`. We recommend you use
-[miniconda](https://docs.conda.io/en/latest/miniconda.html) or, if you already have it installed,
-[conda](https://docs.conda.io/projects/conda/en/latest/).
-
-1. Follow the install steps on https://github.com/jupyter-xeus/xeus-cling to install the C++ kernels
-2. Build and install a _shared_ version of mfem
-    * for example: `make serial SHARED=YES`
-3. Install [pyglvis](https://github.com/glvis/pyglvis)
-    * for the widget frontend
-4. Get [xeus-glvis](https://github.com/glvis/xeus-glvis) and `cp` the header to `{PREFIX}/glvis/xglvis.hpp`
-    * (this could be improved)

-Once you've installed Jupyter, the C++ Kernel, mfem, and glvis start the notebook server (`jupyter-notebook`)
-and open an existing example or a new `C++ 1x` kernel.
-
-You will _always_ need to `#pragma cling load("mfem")` and you may need to point the `cling` runtime at your
-mfem and/or glvis installs, do this with the
-`#pragma cling` [statements](https://xeus-cling.readthedocs.io/en/latest/build_options.html#using-third-party-libraries).

$AMCBRIDGE\ahudym$ AMCBRIDGE\ahudym	1f7f84d7a2	1. Remove "static" keyword from functions used as lambdas on "device" 2. Add _USE_MATH_DEFINES to CmakeLists.txt (without this change VS doesn't "see" this preprocessor in config.hpp) 3. Remove asm definition - asm is not allowed in VS anymore 4. Convert "const double Epsilon" to constexpr (fixes CUDA compilation error)	2021-09-03 11:59:51 +03:00
