# Kokkos Tutorials
This repository contains tutorials for the Kokkos C++ programming
model (github.com/kokkos/kokkos).
## The Kokkos Lectures
We are currently running **The Kokkos Lectures** - an extended version
of our **Intro-Full** Tutorial, spanning 8 modules. For information on that,
Slides and Recordings visit: [The Kokkos Lectures Wiki](https://github.com/kokkos/kokkos-tutorials/wiki/Kokkos-Lecture-Series)
## Other Tutorial Compilations
Tutorials in the **Intro-Short** directory cover
* simple data parallel patterns and policies
* multidimensional array views
* execution and memory spaces
Tutorials in the **Intro-Full** directory cover
* simple data parallel patterns and policies
* multidimensional array views
* execution and memory spaces
* thread safety and atomic operations
* hierarchical data parallel patterns
# Building the Tutorials
All the tutorial folders can be built using CMake.
## CMake
CMake can build against an installed Kokkos library or download one automatically using `FetchContent`.
Without any Kokkos already installed, from an exercise directory, one can run the following:
```shell
cmake -B build_dir # -DKokkos_* options
cmake --build build_dir
```
Kokkos options are described in [CMake options](https://kokkos.org/kokkos-core-wiki/keywords.html).
For example, OpenMP CPU exercises can be built as:
```shell
cmake -B build_openmp -DKokkos_ENABLE_OPENMP=ON
cmake --build build_openmp
```
On Mac, if OpenMP is not available, one can use the Threads backend:
```shell
cmake -B build_threads -DKokkos_ENABLE_THREADS=ON
cmake --build build_threads
```
For a NVIDIA gpu, using gpu arch autodetection:
```shell
cmake -B build_cuda -DKokkos_ENABLE_CUDA=ON
cmake --build build_cuda
```
To pass an already installed Kokkos library, you can use classical CMake variables,
such as `Kokkos_ROOT`, or `CMAKE_PREFIX_PATH`.
