Building

Building Nocta

Prerequisites

• CMake (3.10 or higher)
• C Compiler (GCC, Clang, or MSVC)
• (Optional) CUDA Toolkit (for GPU support)

Building with CMake

1. Create a build directory:

   mkdir build && cd build

2. Configure the project:

   cmake ..

3. Build the project (Release mode recommended):

   cmake --build . --config Release

Build Options

You can configure the build by passing -D<OPTION>=<VALUE> to CMake.

Option	Default	Description
NOCTA_BUILD_EXAMPLES	ON	Build example programs
NOCTA_ENABLE_SIMD	ON	Enable AVX2 SIMD optimizations
NOCTA_ENABLE_OPENMP	ON	Enable OpenMP multi-threading
NOCTA_ENABLE_CUDA	OFF	Enable CUDA/cuBLAS GPU acceleration

Building with CUDA

To enable GPU acceleration, ensure you have the CUDA Toolkit installed.

mkdir build && cd build
cmake .. -DNOCTA_ENABLE_CUDA=ON \
         -DCUDAToolkit_ROOT=/usr/local/cuda-12.x/ \
         -DCMAKE_CUDA_COMPILER=/usr/local/cuda-12.x/bin/nvcc
cmake --build . --config Release
