 # 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 either the `Makefile` or the CMake `CMakeLists.txt` file in each folder. ## Makefiles The raw Makefiles require Makefile variables to be properly configured. In most examples, this is `KOKKOS_PATH` pointing to the Kokkos source directory and `KOKKOS_DEVICES` which contains the list of device backends to build. This will build a new Kokkos library for each exercise. If you are on a system compatible to our AWS instances, you can type ``` make make test ``` in the `Exercises` directory. Compatible means: * X86 with a NVIDIA V100 GPU * kokkos was cloned to ${HOME}/Kokkos/kokkos ## CMake + Spack The CMake files build against an installed Kokkos library. The easiest way to do this is using Spack. There is a `spack.sh` script that automates most of this. The Spack script can be run in any excercise folder with a `CMakeLists.txt`. ```` ../../BuildScripts/spack.sh +openmp %gcc@7.3.0 ```` This will make sure Kokkos is installed with the OpenMP backend for the GCC 7.3.0 compiler. It will then configure CMake and create a `spack-build` folder where `make` can be run. The `spack.sh` accepts the full list of variants and specs as the parent Kokkos package, which can be viewed by running: ```` spack info kokkos ```` The `spack.sh` script uses the special DIY mode of Spack to install dependencies and configure the current source folder to build. For Kokkos Kernels tutorials, there is similarly a `kk-spack.sh` script, e.g. ```` ../../BuildScripts/kk-spack.sh +openmp %gcc@7.3.0 ^kokkos+aggressive_vectorization ```` All the arguments to the script get passed as a spec for the tutorial. We are indirectly configuring Kokkos, hence the `^` notation for specifying the exact Kokkos dependency spec.
