# Contributing to the CUDA Samples
|
||||||
|
|
||||||
|
Thank you for your interest in contributing to the CUDA Samples!
|
||||||
|
|
||||||
|
|
||||||
|
## Getting Started
|
||||||
|
|
||||||
|
1. **Fork & Clone the Repository**:
|
||||||
|
|
||||||
|
Fork the reporistory and clone the fork. For more information, check [GitHub's documentation on forking](https://docs.github.com/en/github/getting-started-with-github/fork-a-repo) and [cloning a repository](https://docs.github.com/en/github/creating-cloning-and-archiving-repositories/cloning-a-repository).
|
||||||
|
|
||||||
|
## Making Changes
|
||||||
|
|
||||||
|
1. **Create a New Branch**:
|
||||||
|
|
||||||
|
```bash
|
||||||
|
git checkout -b your-feature-branch
|
||||||
|
```
|
||||||
|
|
||||||
|
2. **Make Changes**.
|
||||||
|
|
||||||
|
3. **Build and Test**:
|
||||||
|
|
||||||
|
Ensure changes don't break existing functionality by building and running tests.
|
||||||
|
|
||||||
|
For more details on building and testing, refer to the [Building and Testing](#building-and-testing) section below.
|
||||||
|
|
||||||
|
4. **Commit Changes**:
|
||||||
|
|
||||||
|
```bash
|
||||||
|
git commit -m "Brief description of the change"
|
||||||
|
```
|
||||||
|
|
||||||
|
## Building and Testing
|
||||||
|
|
||||||
|
For information on building a running tests on the samples, please refer to the main [README](README.md)
|
||||||
|
|
||||||
|
## Creating a Pull Request
|
||||||
|
|
||||||
|
1. Push changes to your fork
|
||||||
|
2. Create a pull request targeting the `master` branch of the original CUDA Samples repository. Refer to [GitHub's documentation](https://docs.github.com/en/github/collaborating-with-pull-requests/proposing-changes-to-your-work-with-pull-requests/about-pull-requests) for more information on creating a pull request.
|
||||||
|
3. Describe the purpose and context of the changes in the pull request description.
|
||||||
|
|
||||||
|
## Code Formatting (pre-commit hooks)
|
||||||
|
|
||||||
|
The CUDA Samples repository uses [pre-commit](https://pre-commit.com/) to execute all code linters and formatters. These
|
||||||
|
tools ensure a consistent coding style throughout the project. Using pre-commit ensures that linter
|
||||||
|
versions and options are aligned for all developers. Additionally, there is a CI check in place to
|
||||||
|
enforce that committed code follows our standards.
|
||||||
|
|
||||||
|
The linters used by the CUDA Samples are listed in `.pre-commit-config.yaml`.
|
||||||
|
For example, C++ and CUDA code is formatted with [`clang-format`](https://clang.llvm.org/docs/ClangFormat.html).
|
||||||
|
|
||||||
|
To use `pre-commit`, install via `conda` or `pip`:
|
||||||
|
|
||||||
|
```bash
|
||||||
|
conda config --add channels conda-forge
|
||||||
|
conda install pre-commit
|
||||||
|
```
|
||||||
|
|
||||||
|
```bash
|
||||||
|
pip install pre-commit
|
||||||
|
```
|
||||||
|
|
||||||
|
Then run pre-commit hooks before committing code:
|
||||||
|
|
||||||
|
```bash
|
||||||
|
pre-commit run
|
||||||
|
```
|
||||||
|
|
||||||
|
By default, pre-commit runs on staged files (only changes and additions that will be committed).
|
||||||
|
To run pre-commit checks on all files, execute:
|
||||||
|
|
||||||
|
```bash
|
||||||
|
pre-commit run --all-files
|
||||||
|
```
|
||||||
|
|
||||||
|
Optionally, you may set up the pre-commit hooks to run automatically when you make a git commit. This can be done by running:
|
||||||
|
|
||||||
|
```bash
|
||||||
|
pre-commit install
|
||||||
|
```
|
||||||
|
|
||||||
|
Now code linters and formatters will be run each time you commit changes.
|
||||||
|
|
||||||
|
You can skip these checks with `git commit --no-verify` or with the short version `git commit -n`, althoguh please note
|
||||||
|
that this may result in pull requests being rejected if subsequent checks fail.
|
||||||
|
|
||||||
|
## Review Process
|
||||||
|
|
||||||
|
Once submitted, maintainers will be automatically assigned to review the pull request. They might suggest changes or improvements. Constructive feedback is a part of the collaborative process, aimed at ensuring the highest quality code.
|
||||||
|
|
||||||
|
For constructive feedback and effective communication during reviews, we recommend following [Conventional Comments](https://conventionalcomments.org/).
|
||||||
|
|
||||||
|

### Enabling On-GPU Debugging
|
||||||
|
|
||||||
|
NVIDIA GPUs support on-GPU debugging through cuda-gdb. Enabling this may significantly affect application performance as certain compiler optimizations are disabled
|
||||||
|
in this configuration, hence it's not on by default. Enablement of on-device debugging is controlled via the `-G` switch to nvcc.
|
||||||
|
|
||||||
|
To enable cuda-gdb for samples builds, define the `ENABLE_CUDA_DEBUG` flag on the CMake command line. For example:
|
||||||
|
|
||||||
|
```
|
||||||
|
cmake -DENABLE_CUDA_DEBUG=True ...

```

## Running All Samples as Tests
|
||||||
|
|
||||||
|
It's important to note that the CUDA samples are _not_ intended as a validation suite for CUDA. They do not cover corner cases, they do not completely cover the
|
||||||
|
runtime and driver APIs, are not intended for performance benchmarking, etc. That said, it can sometimes be useful to run all of the samples as a quick sanity check and
|
||||||
|
we provide a script to do so, `run_tests.py`.
|
||||||
|
|
||||||
|
This Python3 script finds all executables in a subdirectory you choose, matching application names with command line arguments specified in `test_args.json`. It accepts
|
||||||
|
the following command line arguments:
|
||||||
|
|
||||||
|
| Switch | Purpose | Example |
|
||||||
|
| ---------- | -------------------------------------------------------------------------------------------------------------- | ----------------------- |
|
||||||
|
| --dir | Specify the root directory to search for executables (recursively) | --dir ./build/Samples |
|
||||||
|
| --config | JSON configuration file for executable arguments | --config test_args.json |
|
||||||
|
| --output | Output directory for test results (stdout saved to .txt files - directory will be created if it doesn't exist) | --output ./test |
|
||||||
|
| --args | Global arguments to pass to all executables (not currently used) | --args arg_1 arg_2 ... |
|
||||||
|
| --parallel | Number of applications to execute in parallel. | --parallel 8 |
|
||||||
|
|
||||||
|
|
||||||
|
Application configurations are loaded from `test_args.json` and matched against executable names (discarding the `.exe` extension on Windows).
|
||||||
|
|
||||||
|
The script returns 0 on success, or the first non-zero error code encountered during testing on failure. It will also print a condensed list of samples that failed, if any.
|
||||||
|
|
||||||
|
There are three primary modes of configuration:
|
||||||
|
|
||||||
|
**Skip**
|
||||||
|
|
||||||
|
An executable configured with "skip" will not be executed. These generally rely on having attached graphical displays and are not suited to this kind of automation.
|
||||||
|
|
||||||
|
Configuration example:
|
||||||
|
```json
|
||||||
|
"fluidsGL": {
|
||||||
|
"skip": true
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
You will see:
|
||||||
|
```
|
||||||
|
Skipping fluidsGL (marked as skip in config)
|
||||||
|
```
|
||||||
|
|
||||||
|
**Single Run**
|
||||||
|
|
||||||
|
For executables to run one time only with arguments, specify each argument as a list entry. Each entry in the JSON file will be appended to the command line, separated
|
||||||
|
by a space.
|
||||||
|
|
||||||
|
All applications execute from their current directory, so all paths are relative to the application's location.
|
||||||
|
|
||||||
|
Note that if an application needs no arguments, this entry is optional. An executable found without a matching entry in the JSON will just run as `./application` from its
|
||||||
|
current directory.
|
||||||
|
|
||||||
|
Configuration example:
|
||||||
|
```json
|
||||||
|
"ptxgen": {
|
||||||
|
"args": [
|
||||||
|
"test.ll",
|
||||||
|
"-arch=compute_75"
|
||||||
|
]
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
You will see:
|
||||||
|
```
|
||||||
|
Running ptxgen
|
||||||
|
Command: ./ptxgen test.ll -arch=compute_75
|
||||||
|
Test completed with return code 0
|
||||||
|
```
|
||||||
|
|
||||||
|
**Multiple Runs**
|
||||||
|
|
||||||
|
For executables to run multiple times with different command line arguments, specify any number of sets of args within a "runs" list.
|
||||||
|
|
||||||
|
As with single runs, all applications execute from their current directory, so all paths are relative to the application's location.
|
||||||
|
|
||||||
|
Configuration example:
|
||||||
|
```json
|
||||||
|
"recursiveGaussian": {
|
||||||
|
"runs": [
|
||||||
|
{
|
||||||
|
"args": [
|
||||||
|
"-sigma=10",
|
||||||
|
"-file=data/ref_10.ppm"
|
||||||
|
]
|
||||||
|
},
|
||||||
|
{
|
||||||
|
"args": [
|
||||||
|
"-sigma=14",
|
||||||
|
"-file=data/ref_14.ppm"
|
||||||
|
]
|
||||||
|
},
|
||||||
|
{
|
||||||
|
"args": [
|
||||||
|
"-sigma=18",
|
||||||
|
"-file=data/ref_18.ppm"
|
||||||
|
]
|
||||||
|
},
|
||||||
|
{
|
||||||
|
"args": [
|
||||||
|
"-sigma=22",
|
||||||
|
"-file=data/ref_22.ppm"
|
||||||
|
]
|
||||||
|
}
|
||||||
|
]
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
You will see:
|
||||||
|
```
|
||||||
|

||||||
|

|
||||||
|
```
|
||||||
|
|
||||||
|
### Example Usage
|
||||||
|
|
||||||
|
Here is an example set of commands to build and test all of the samples.
|
||||||
|
|
||||||
|
First, build:
|
||||||
|
```bash
|
||||||
|
mkdir build
|
||||||
|
cd build
|
||||||
|
cmake ..
|
||||||
|
make -j$(nproc)
|
||||||
|
```
|
||||||
|
|
||||||
|
Now, return to the samples root directory and run the test script:
|
||||||
|
```bash
|
||||||
|
cd ..
|
||||||
|
python3 run_tests.py --output ./test --dir ./build/Samples --config test_args.json
|
||||||
|
```
|
||||||
|
|
||||||
|
If all applications run successfully, you will see something similar to this (the specific number of samples will depend on your build type
|
||||||
|
and system configuration):
|
||||||
|
|
||||||
|
```
|
||||||
|
Test Summary:
|
||||||
|
Ran 199 test runs for 180 executables.
|
||||||
|
All test runs passed!
|
||||||
|
```
|
||||||
|
|
||||||
|
If some samples fail, you will see something like this:
|
||||||
|
|
||||||
|
```
|
||||||
|
Test Summary:
|
||||||
|
Ran 199 test runs for 180 executables.
|
||||||
|
Failed runs (2):
|
||||||
|
bicubicTexture (run 1/5): Failed (code 1)
|
||||||
|
Mandelbrot (run 1/2): Failed (code 1)
|
||||||
|
```
|
||||||
|
|
||||||
|
You can inspect the stdout logs in the output directory (generally `APM_<application_name>.txt` or `APM_<application_name>.run<n>.txt`) to help
|
||||||
|
determine what may have gone wrong from the output logs. Please file issues against the samples repository if you believe a sample is failing
|
||||||
|
incorrectly on your system.

This sample implements matrix multiplication and is exactly the same as Chapter 6 of the programming guide. It has been written for clarity of exposition to illustrate various CUDA programming principles, not with the goal of providing the most performant generic kernel for matrix multiplication. To illustrate GPU performance for matrix multiply, this sample also shows how to use the new CUDA 4.0 interface for CUBLAS to demonstrate high-performance performance for matrix multiplication.

This sample implements matrix multiplication and is exactly the same as the second example of the [Shared Memory](https://docs.nvidia.com/cuda/cuda-c-programming-guide/index.html#shared-memory) section of the programming guide. It has been written for clarity of exposition to illustrate various CUDA programming principles, not with the goal of providing the most performant generic kernel for matrix multiplication. To illustrate GPU performance for matrix multiply, this sample also shows how to use the CUDA 4.0+ interface for cuBLAS to demonstrate high-performance performance for matrix multiplication.

This sample implements matrix multiplication and is exactly the same as Chapter 6 of the programming guide. It has been written for clarity of exposition to illustrate various CUDA programming principles, not with the goal of providing the most performant generic kernel for matrix multiplication. To illustrate GPU performance for matrix multiply, this sample also shows how to use the new CUDA 4.0 interface for CUBLAS to demonstrate high-performance performance for matrix multiplication.

This sample implements matrix multiplication and is exactly the same as the second example of the [Shared Memory](https://docs.nvidia.com/cuda/cuda-c-programming-guide/index.html#shared-memory) section of the programming guide. It has been written for clarity of exposition to illustrate various CUDA programming principles, not with the goal of providing the most performant generic kernel for matrix multiplication. To illustrate GPU performance for matrix multiply, this sample also shows how to use the CUDA 4.0+ interface for cuBLAS to demonstrate high-performance performance for matrix multiplication.
