HEaaN GPU Component Overview

Component Structure

Component Roles

Component	Layer	Responsibility	Key Features
Devices.hpp	High-level	Device abstraction and management	Device type management Device state control Scope-based device switching
CudaTools.hpp	Low-level	CUDA runtime interface	CUDA device operations Memory Management Profiling support

Example flow

// High-level usage (Device.hpp)
Device gpuDevice(DeviceType::GPU);
{
    scopedCudaDeviceSelector selector(gpuDevice);
    // Device.hpp internally uses CudaTools.hpp
    // to manage CUDA device
}

// Low-level usage (CudaTools.hpp)
if(HEaaN::CudaTools::isAvailable()) {
    HEaaN::CudaTools::cudaSetDevice(0);
    // ...
    HEaaN::CudaTools::cudaDeviceSynchronize();
}
