parallelbrot

GPU-accelerated Mandelbrot set renderer with OpenCL (cross-platform), CUDA (NVIDIA), and CPU backends.

Build & Run

Install dependencies first (Ubuntu/Debian):

make install-deps-ubuntu   # OpenCL deps
make install-cuda-ubuntu   # CUDA deps (NVIDIA only)

Then build and run:

make opencl && build/mandelbrot_opencl   # Any GPU (recommended)
make cuda   && build/mandelbrot_cuda     # NVIDIA only (fastest)
make cpu    && build/mandelbrot_cpu      # CPU fallback
make clean                               # Remove build artifacts

For other distros, replace ubuntu with fedora or arch.
