Contributing to VTK-m
=====================
This page documents at a very high level how to contribute to VTK-m.
Please check our [developer instructions][] for a more detailed guide to
developing and contributing to the project.
This page documents how to develop VTK-m through [Git](http://git-scm.com).
1. Register [GitLab Access] to create an account and select a user name.
Git is an extremely powerful version control tool that supports many
different "workflows" for individual development and collaboration.
Here we document procedures used by the VTK-m development community.
In the interest of simplicity and brevity we do *not* provide an
explanation of why we use this approach.
Setup
-----
Before you begin, perform initial setup:
1. Register [GitLab Access][] to create an account and select a user name.
2. [Fork VTK-m][] into your user's namespace on GitLab.
3. Create a local clone of the main VTK-m repository:
3. Follow the [download instructions](download.md#clone) to create a
local clone of the main VTK repository:
$ git clone https://gitlab.kitware.com/vtk/vtk-m.git vtkm
$ cd vtkm
$ git clone https://gitlab.kitware.com/vtk/vtk-m.git VTK
$ cd vtk-m
The main repository will be configured as your `origin` remote.
4. Associate your GitLab fork of VTK-m VTK-m repository:
4. (Optional but highly recommended.)
[Register](https://open.cdash.org/register.php) with the VTK-m project
on Kitware's CDash instance to better know how your code performs in
regression tests. After registering and signing in, click on
"All Dashboards" link in the upper left corner, scroll down and click
"Subscribe to this project" on the right of VTK-m.
$ git remote add gitlab git@gitlab.com:username/vtk-m.git
[GitLab Access]: https://gitlab.kitware.com/users/sign_in
[Fork VTK-m]: https://gitlab.kitware.com/vtk/vtk-m/forks/new
Your fork will be configured as your `gitlab` remote.
Workflow
--------
5. Edit files and create commits (repeat as needed):
VTK-m development uses a [branchy workflow][] based on topic branches.
Our collaboration workflow consists of three main steps:
1. Local Development:
* [Update](#update)
* [Create a Topic](#create-a-topic)
2. Code Review (requires [GitLab Access][]):
* [Share a Topic](#share-a-topic)
* [Create a Merge Request](#create-a-merge-request)
* [Review a Merge Request](#review-a-merge-request)
* [Revise a Topic](#revise-a-topic)
3. Integrate Changes:
* [Merge a Topic](#merge-a-topic) (requires permission in GitLab)
[branchy workflow]: http://public.kitware.com/Wiki/Git/Workflow/Topic
Update
------
1. Update your local `master` branch:
$ git checkout master
$ git pull
2. Optionally push `master` to your fork in GitLab:
$ git push gitlab master
Create a Topic
--------------
All new work must be committed on topic branches.
Name topics like you might name functions: concise but precise.
A reader should have a general idea of the feature or fix to be developed given just the branch name.
1. To start a new topic branch:
$ git fetch origin
2. For new development, start the topic from `origin/master`:
$ git checkout -b my-topic origin/master
3. Edit files and create commits (repeat as needed):
$ edit file1 file2 file3
$ git add file1 file2 file3
$ git commit
6. Push commits in your topic branch to your fork in GitLab:
Caveats:
* Data files must be placed in either the root data directory, or a
folder explicitly named 'data'. This is required as VTK-m uses Git-LFS
to efficiently support data files.
Guidelines for Commit logs
--------------------------
Remember to *motivate & summarize*. When writing commit logs, make sure
that there is enough information there for any developer to read and glean
relevant information such as:
1. Is this change important and why?
2. If addressing an issue, which issue(s)?
3. If a new feature, why is it useful and/or necessary?
4. Are there background references or documentation?
A short description of what the issue being addressed and how will go a long way
towards making the log more readable and the software more maintainable.
Style guidelines for commit logs are as follows:
1. Separate subject from body with a blank line
2. Limit the subject line to 60 characters
3. Capitalize the subject line
4. Use the imperative mood in the subject line e.g. "Refactor foo" or "Fix Issue #12322",
instead of "Refactoring foo", or "Fixing issue #12322".
5. Wrap the body at 80 characters
6. Use the body to explain `what` and `why` and if applicable a brief `how`.
Share a Topic
-------------
When a topic is ready for review and possible inclusion, share it by pushing
to a fork of your repository in GitLab. Be sure you have registered and
signed in for [GitLab Access][] and created your fork by visiting the main
[VTK-m GitLab][] repository page and using the "Fork" button in the upper right.
[VTK-m GitLab]: https://gitlab.kitware.com/vtk/vtk-m
1. Checkout the topic if it is not your current branch:
$ git checkout my-topic
2. Push commits in your topic branch to your fork in GitLab:
$ git push gitlab HEAD
7. Visit your fork in GitLab, browse to the "**Merge Requests**" link on the
left, and use the "**New Merge Request**" button in the upper right to
create a Merge Request.
Notes:
* If you are revising a previously pushed topic and have rewritten the
topic history, add `-f` or `--force` to overwrite the destination.
The output will include a link to the topic branch in your fork in GitLab
and a link to a page for creating a Merge Request.
Create a Merge Request
----------------------
Visit your fork in GitLab, browse to the "**Merge Requests**" link on the
left, and use the "**New Merge Request**" button in the upper right to
reach the URL printed at the end of the [previous step](#share-a-topic).
It should be of the form:
https://gitlab.kitware.com/<username>/vtk-m/merge_requests/new
Follow these steps:
1. In the "**Source branch**" box select the `<username>/vtk-m` repository
and the `my-topic` branch.
2. In the "**Target branch**" box select the `vtk/vtk-m` repository and
the `master` branch. It should be the default.
3. Use the "**Compare branches**" button to proceed to the next page
and fill out the merge request creation form.
4. In the "**Title**" field provide a one-line summary of the entire
topic. This will become the title of the Merge Request.
Example Merge Request Title:
Add OpenMP Device Adapter
5. In the "**Description**" field provide a high-level description
of the change the topic makes and any relevant information about
how to try it.
* Use `@username` syntax to draw attention of specific developers.
This syntax may be used anywhere outside literal text and code
blocks. Or, wait until the [next step](#review-a-merge-request)
and add comments to draw attention of developers.
* Optionally use a fenced code block with type `message` to specify
text to be included in the generated merge commit message when the
topic is [merged](#merge-a-topic).
Example Merge Request Description:
This branch adds a new device adapter that uses new OpenMP 4+ features
including Task groups to better handle unbalanced and irregular domains
```message
Add a OpenMP 4+ task-based device adapter.
```
Cc: @user1 @user2
6. The "**Assign to**", "**Milestone**", and "**Labels**" fields
may be left blank.
7. Use the "**Submit merge request**" button to create the merge request
and visit its page.
Guidelines for Merge Requests
-----------------------------
Remember to *motivate & summarize*. When creating a merge request, consider the
reviewers and future perusers of the software. Provide enough information to motivate
the merge request such as:
1. Is this merge request important and why?
2. If addressing an issue, which issue(s)?
3. If a new feature, why is it useful and/or necessary?
4. Are there background references or documentation?
Also provide a summary statement expressing what you did and if there is a choice
in implementation or design pattern, the rationale for choosing a certain path.
Notable software or data features should be mentioned as well.
A well written merge request will motivate your reviewers, and bring them up
to speed faster. Future software developers will be able to understand the
reasons why something was done, and possibly avoid chasing down dead ends,
Although it may take you a little more time to write a good merge request,
you’ll likely see payback in faster reviews and better understood and
maintainable software.
VTK-m uses GitLab for code review and Buildbot to test proposed
patches before they are merged.
Review a Merge Request
----------------------
Our [Issue Tracker][] is used to document feature requests and technical issues.
Add comments mentioning specific developers using `@username` syntax to
draw their attention and have the topic reviewed. After typing `@` and
some text, GitLab will offer completions for developers whose real names
or user names match.
Our [Wiki][] is out to propose new infrastructure designs and host other
documentation.
Comments use [GitLab Flavored Markdown][] for formatting. See GitLab
documentation on [Special GitLab References][] to add links to things
like merge requests and commits in other repositories.

### Reviews ###
Reviewers may add comments providing feedback or to acknowledge their
approval. All comments use the [GitLab Flavored Markdown][], any line of a
comment may be exactly one of the following votes followed by nothing but
whitespace before the end of the line:
* `-1` or :-1: (`:-1:`) means "The change is not ready for integration."
* `+1` or :+1: (`:+1:`) means "The change is ready for integration."
These are used to inform the author that a merge srequest has been approved
for [merging]((#merge-a-topic).
#### Fetching Changes ####s
One may fetch the changes associated with a merge request by using
the `git fetch` command line shown at the top of the Merge Request
page. It is of the form:
$ git fetch https://gitlab.kitware.com/$username/vtk-m.git $branch
This updates the local `FETCH_HEAD` to refer to the branch.
There are a few options for checking out the changes in a work tree:
* One may checkout the branch:
$ git checkout FETCH_HEAD -b $branch
or checkout the commit without creating a local branch:
$ git checkout FETCH_HEAD
* Or, one may cherry-pick the commits to minimize rebuild time:
$ git cherry-pick ..FETCH_HEAD
### Robot Reviews ###
The "Kitware Robot" automatically performs basic checks on the commits
and adds a comment acknowledging or rejecting the topic. This will be
repeated automatically whenever the topic is updated.
A re-check may be explicitly requested by adding a comment with a single
[*trailing* line](#trailing-lines):
Do: check
A topic cannot be [merged](#merge-a-topic) until the automatic review
succeeds.
### Testing ###
VTK-m has a [buildbot](http://buildbot.net) instance watching for merge requests
to test. Each time a merge request is updated the buildbot user (@buildbot)
will automatically trigger a new build on all VTK-m buildbot workers. The
buildbot user (@buildbot) will respond with a comment linking to the CDash
results when it schedules builds.
The buildbot user (@buildbot) will also respond to any comment with the form:
Do: test
The `Do: test` command accepts the following arguments:
* `--oneshot`
only build the *current* hash of the branch; updates will not be built
using this command
* `--stop`
clear the list of commands for the merge request
* `--superbuild`
build the superbuilds related to the project
* `--clear`
clear previous commands before adding this command
* `--regex-include <arg>` or `-i <arg>`
only build on builders matching `<arg>` (a Python regular expression)
* `--regex-exclude <arg>` or `-e <arg>`
excludes builds on builders matching `<arg>` (a Python regular
expression)
Multiple `Do: test` commands may be given in separate comments. Buildbot may
skip tests for older branch updates that have not started before a test for
a new update is requested.
Builder names always follow this pattern:
project-host-os-libtype-buildtype+feature1+feature2
* project: always `vtk-m`
* host: the buildbot host
* os: one of `windows`, `osx`, or `linux`
* libtype: `shared` or `static`
* buildtype: `release` or `debug`
* feature: alphabetical list of features enabled for the build
Revise a Topic
--------------
If a topic is approved during GitLab review, skip to the
[next step](#merge-a-topic). Otherwise, revise the topic
and push it back to GitLab for another review as follows:
1. Checkout the topic if it is not your current branch:
$ git checkout my-topic
2. To revise the `3`rd commit back on the topic:
$ git rebase -i HEAD~3
(Substitute the correct number of commits back, as low as `1`.)
Follow Git's interactive instructions.
3. Return to the [above step](#share-a-topic) to share the revised topic.
Merge a Topic
-------------
After a topic has been reviewed and approved in a GitLab Merge Request,
authorized developers may add a comment with a single
[*trailing* line](#trailing-lines):
Do: merge
to ask that the change be merged into the upstream repository. By
convention, only merge if you have recieved `+1` . Do not request a merge if
any `-1` review comments have not been resolved.
### Merge Success ###
If the merge succeeds the topic will appear in the upstream repository
`master` branch and the Merge Request will be closed automatically.
### Merge Failure ###
If the merge fails (likely due to a conflict), a comment will be added
describing the failure. In the case of a conflict, fetch the latest
upstream history and rebase on it:
$ git fetch origin
$ git rebase origin/master
Return to the [above step](#share-a-topic) to share the revised topic.

## VTK-m ##
One of the biggest recent changes in high-performance computing is the increasing use of accelerators. Accelerators contain processing cores that independently are inferior to a core in a typical CPU, but these cores are replicated and grouped such that their aggregate execution provides a very high computation rate at a much lower power. Current and future CPU processors also require much more explicit parallelism. Each successive version of the hardware packs more cores into each processor, and technologies like hyperthreading and vector operations require even more parallel processing to leverage each core’s full potential.
VTK-m is a toolkit of scientific visualization algorithms for emerging processor architectures. VTK-msupports the fine-grained concurrency for data analysis and visualization algorithms required to drive extreme scale computing by providing abstract models for data and execution that can be applied to a variety of algorithms across many different processor architectures.

Building
========
VTK-m supports all majors platforms ( Windows, Linux, OSX ), and uses CMake
to generate all the build rules for the project.
```
git clone https://gitlab.kitware.com/vtk/vtk-m.git vtkm
mkdir vtkm-build
cd vtkm-build
cmake-gui ../vtkm
$ git clone https://gitlab.kitware.com/vtk/vtk-m.git
$ mkdir vtkm-build
$ cd vtkm-build
$ cmake-gui ../vtk-m
$ make -j<N>
$ make test
```
A detailed walk-through of installing and building VTK-m can be found on our [Contributing page](http://m.vtk.org/index.php/Contributing_to_VTK-m)
The VTK-m CMake configuration supports several options, including what specific
device adapters ( e.g. CUDA, TBB ) that you wish to enable. Here are some
relevant options
| Variable | Description |
|-----------------------------|-----------------------------|
| BUILD_SHARED_LIBS | Enabled by default. Build all VTK-m libraries as shared libraries. |
| CMAKE_BUILD_TYPE | This statically specifies what build type (configuration) will be built in this build tree. Possible values are empty, Debug, Release, RelWithDebInfo and MinSizeRel. This variable is only meaningful to single-configuration generators (such as make and Ninja). |
| CMAKE_INSTALL_PREFIX | Directory to install VTK-m into. |
| VTKm_ENABLE_EXAMPLES | Disabled by default. Turn on building of simple examples of using VTK-m. |
| VTKm_ENABLE_BENCHMARKS | Disabled by default. Turn on additional timing tests. |
| VTKm_ENABLE_CUDA | Disabled by default. Enable CUDA backend. |
| VTKm_CUDA_Architecture | Defaults to native. Specify what GPU architecture(s) to build CUDA code for, options include native, fermi, kepler, maxwell, and pascal. |
| VTKm_ENABLE_TBB | Disabled by default. Enable Intel Threading Building Blocks backend. |
| VTKm_ENABLE_TESTING | Enabled by default. Turn on header, unit, worklet, and filter tests. |
| VTKm_ENABLE_RENDERING | Enabled by default. Turn on the rendering module. |
| VTKm_USE_64BIT_IDS | Enabled by default. This is the size of integers used to index arrays, points, cells, etc. Use 64 bit precision when on, 32 bit precision when off. |
| VTKm_USE_DOUBLE_PRECISION | Disabled by default. Precision to use in floating point numbers when no other precision can be inferred. Use 64 bit precision when on, 32 bit precision when off. |
Learning
========
VTK-m offers numerous different ways to learn how to use the provided components.
If you are interested in a high level overview of VTK-m a good place to start
is with the IEEE Vis talk ["VTK-m: Accelerating the Visualization Toolkit for Massively Threaded Architectures"](http://m.vtk.org/images/2/29/VTKmVis2016.pptx) or the older and more technical
presentation
["VTK-m Overview for Intel Design Review"](http://m.vtk.org/images/a/a4/VTKmIntelMeet.pptx).
If you are interested in learning how to use the existing VTK-m codebase,
or how to integrate into your own project, we recommend reading "Part 1: Getting Started"
and "Part 2: Using VTK-m" of the [VTK-m Users Guide][].
If you want to contribute to VTK-m we recommend reading the following sections
of the [VTK-m Users Guide][].
+ "Part 2: Using VTK-m"
- Covers the core fundamental components of VTK-m including data model, worklets, and filters.
- "Part 3: Developing with VTK-m"
- Covers how to develop new worklets and filters.
- "Part 4: Advanced Development"
- Covers topics such as new worklet tags, opengl interop and custom device adapters .
Example
=======
The VTK-m source distribution includes a number of examples. The goal of the VTK-m examples is to illustrate specific VTK-m concepts in a consistent and simple format. However, these examples only cover a small part of the capabilities of VTK-m.
Below is a simple example of using VTK-m to load a VTK image file, run the
Marching Cubes algorithm on it, and render the results to an image:
```cpp
vtkm::io::reader::VTKDataSetReader reader("path/to/vtk_image_file");
inputData = reader.ReadDataSet();
vtkm::Float64 isovalue = 100.0f;
std::string fieldName = "pointvar";
// Create an isosurface filter
vtkm::filter::MarchingCubes filter;
filter.SetIsoValue(0, isovalue);
vtkm::filter::ResultDataSet result = filter.Execute( inputData,
inputData.GetField(fieldName) );
filter.MapFieldOntoOutput(result, inputData.GetField(fieldName));
// compute the bounds and extends of the input data
vtkm::Bounds coordsBounds =
inputData.GetCoordinateSystem().GetBounds();
vtkm::Vec<vtkm::Float64,3> totalExtent( coordsBounds.X.Length(),
coordsBounds.Y.Length(),
coordsBounds.Z.Length() );
vtkm::Float64 mag = vtkm::Magnitude(totalExtent);
vtkm::Normalize(totalExtent);
// setup a camera and point it to towards the center of the input data
vtkm::rendering::Camera camera;
camera.ResetToBounds(coordsBounds);
camera.SetLookAt(totalExtent * (mag * .5f));
camera.SetViewUp(vtkm::make_Vec(0.f, 1.f, 0.f));
camera.SetClippingRange(1.f, 100.f);
camera.SetFieldOfView(60.f);
camera.SetPosition(totalExtent * (mag * 2.f));
vtkm::rendering::ColorTable colorTable("thermal");
// Create a mapper, canvas and view that will be used to render the scene
vtkm::rendering::Scene scene;
vtkm::rendering::MapperRayTracer mapper;
vtkm::rendering::CanvasRayTracer canvas(512,512);
vtkm::rendering::Color bg(0.2f, 0.2f, 0.2f, 1.0f);
// Render an image of the output isosurface
vtkm::cont::DataSet& outputData = result.GetDataSet();
scene.AddActor(vtkm::rendering::Actor(outputData.GetCellSet(),
outputData.GetCoordinateSystem(),
outputData.GetField(fieldName),
colorTable));
vtkm::rendering::View3D view(scene, mapper, canvas, camera, bg);
view.Initialize();
view.Paint();
view.SaveAs("demo_output.pnm");
```
