cuda-nbody

This is is a port of the CUDA NBody sample code: https://github.com/NVIDIA/cuda-samples/blob/master/Samples/5_Domain_Specific/nbody/README.md

Goals:

• Isolate the code from the other samples and utilities and build in a self-contained manner.
• Manage (non-CUDA) dependencies with vcpkg.
• Setup project in a manner that is largely inspired by: https://github.com/friendlyanon/cmake-init
• Remove legacy cruft and generally simplify the codebase.

Clone recursively to obtain vcpkg and the project dependencies. e.g.

$ git clone --recursive [email protected]:j-horner/cuda-nbody.git

Additional dependencies

• A recent version of CMake i.e 3.31.6 or later.
• A recent compiler supporting C++23 or later.
• ninja-build on Linux, if not change the "generator" from "Ninja" to "Unix Makefiles"
• Cppcheck on Windows if you want to use the "cppcheck" preset.

See the BUILDING document.

Building and installing

Tested building in following environments:

• Visual Studio 2022

If your IDE has good native support for CMake Presets it should work fine. Alternatively, on Linux, the provided build_script.sh can be used (mostly a wwrapper around standard cmake commands), e.g. for the dev-unix preset:

$ ./build_script.sh dev-unix --run-tests

See the BUILDING document for some more information.
