Installation

Fern is now supported by the Gern repository. Gern adds support for GPUs and contains Fern-style CPU support. Gern is under 🚧 active development 🚧.

Fern is an open-source project available at https://github.com/manya-bansal/gern.

It is written in C++20 and requires CMake version 3.30 or higher to build.

Getting the Repository

First, clone the repository from github.

$ git clone [email protected]:manya-bansal/gern.git

Fern uses vcpkg to manage its dependencies. Follow the official guide to download and install vcpkg: Get Started with vcpkg

Once installed, set the VCPKG_ROOT environment variable to point to your vcpkg directory.

Fern uses cmake as its build system. Before building Fern, ensure that cmake is installed on your system. Fern requires cmake 3.30 and above.

You can download the latest version of CMake from the official website: CMake Downloads

Now that VCPKG_ROOT is set and you have downloaded the repository, build the repository from the gern directory:

$ cmake -DGern_CUDA_ARCH=<89,90..,etc> --preset dev 
$ cmake --build build/dev

If -DGern_CUDA_ARCH is not set, none of the GPU kernels will be run during tests.

To run tests, execute:

$ ctest --test-dir build/dev
